4. Unraveling the gender diversity in Quantum Science and Tech
Mentor: Oxana Mishina (Italian National Institute of Optics – CNR, c/o SISSA)
Interns: Amol Aggarwal, Eyad Elsenany, George Johny, Isago Mangwane, Vaishnavi Markunde, Bruna Shinohara De Mendonça, Srijita Nandi, Nikhil Kumar Parida, Kritika Rag, Monica Ramchandani, Juweria Sayed, Amina Sellami, Ananya Shrivastava, Sammith Singamsetty

Such research was done for computer science and brought up a lot of surprises on gender diversity in the area, that was previously unspoken. This project aims to collect more diverse gender participation in the progress of Quantum Science and technology.

5. Continuous variable quantum random number generators
Mentor: Shashank Gupta (Qnu Labs, India)
Interns: Arnav Arora, Akash Chandra Behera, Aditya Dev, Akhil Gupta
Project description: There are two categories of random number generators, 1. Pseudo random number generators (PRNGs) use mathematical algorithms to generate random numbers. 2. True random number generators (TRNGs) that utilizes physical phenomenon to generate random numbers. The major disadvantage with PRNGs is the initial seed that if known, one can predict the sequence of the generated numbers. Quantum phenomena being intrinsically random are used to generate random numbers. Such random number generators are called Quantum random number generators (QRNGs). Single-photon source and detectors are the essential requirement for the traditional QRNGs based on discrete variables making them expensive as well as lesser rate. However, the other approach based on continuous variables uses a coherent light source along with homodyne or heterodyne detectors for this purpose offering higher rate and being cost-effective. In this project, the objective is to design a new QRNG protocol based on continuous variables to further improve the rate and strengthen security.

6. Pseudo Quantum random number generators using generalised permutation matrices
Mentor: Shashank Gupta (Qnu Labs)
Interns: Ieline Ahmed, Deepshikha Jangir, Shashwat Sharma, Yash Upadhyay
Project description: Random number generators are mainly of two types – algorithmic or based on physical phenomena. True random number generators based on quantum phenomena are quantum resilient but are costly and not agile for diverse applications. Here we will look forward to develops some algorithmic quantum resilient random number generators using generalised permutation matrices.

7. QuiZX: Quantum Computation with ZX Calculus using Rust Programming
Mentor: Srinjoy Ganguly, Prateek Jain (Fractal Analytics)
Interns: Luis Gerardo Ayala Bertel, Vaishnavi Chandilkar, Shalini D, Calum Holker
Project description: In quantum computing, the tasks which we want to accomplish are encoded in the form of quantum circuits and they are executed on real quantum hardware to achieve desired results. These quantum circuits are unitary in nature and therefore can be easily written in various forms by using different quantum gates or rewriting with different quantum gates to simplify them. The ZX calculus is a graphical mathematics technique which helps in the efficient optimization (by using rewrite rules of simplification) of quantum circuits by representing them in terms of diagrams which look like spiders. ZX calculus has its foundations laid in category theory and is now utilized by several quantum computing companies for QNLP, Quantum Compositional Intelligence, MBQC, quantum software design, quantum compilers, quantum OS, circuit optimization, etc. This project proposes the exploration of QuiZX, a ZX calculus package based on the Rust programming language translated from its Python counterpart PyZX because of the performance boost Rust can provide to various applications. It has been found that Rust provides 5000x speedup compared to PyZX! The primary purpose of this project is threefold: Learning the basics Rust programming language with proper technical reports in LaTeX, exploration of QuiZX to develop detailed documentation and coding tutorials for its various features using GitHub pages and benchmarking QuiZX and PyZX together. The final outcomes of the project involves having a website developed and a detailed technical report ready outlining the work carried out during the internship period.

8. N-Queens Solver Implementation for Optimization of Communication System by Qiskit
Mentor: Kuan-Cheng Chen (Imperial College London)
Interns: Martyna Czuba, Cristian Galvis, Mohamed Amine Garrach, Adrian Harkness, Milan John, Manul Riteshkumar Patel, Stefan Talpa
Project description: The N-queens problem is to find the position of N queens on an N by N chess board such that no queens attack each other. The excluded diagonals N-queens problem is a variation where queens cannot be placed on some predefined fields along diagonals. This variation is proven NP-complete and the parameter regime to generate hard instances that are intractable with current classical algorithms is known. We want to propose a special purpose quantum simulator that implements the excluded diagonals N-queens completion problem using atoms in an optical lattice and cavity-mediated long-range interactions. The implementation of this project has no overhead from the embedding allowing to directly probe for a possible quantum advantage in near term devices for optimization problems.

9. References to Quantum Technologies in Cultural Artefacts
Mentor: Zeki Seskir (KIT-ITAS)
Interns: Natsai Chidavaenzi, Celestine Ikoki, Alizah Memon, Debarshi Mukherjee, Ivan Rojas, Jerin Saji, Samarjit Singh, Vimbai Zisengwe
Project description: Being referenced in cultural artefacts such as books, movies, games, and TV shows is an important indicator of the interest in and relevance of a technology to the society. Furthermore, the content and the context of the reference gives us insight into how the technology is perceived or envisioned by the public and creators of these cultural artefacts. In this regard, for this project we will be investigating how quantum technologies is covered by the mainstream cultural artefacts. We will investigate the references to QT in TV shows , mainstream games (like ANNO 2205, Stellaris, Call of Duty: Black Ops etc.), books, and movies. Although it may sound like just playing games and watching fun things, for the project we’ll ask the interns to employ coding techniques used for qualitative research in social sciences. This requires some initial training, so initially we’ll cover some qualitative research methods such as thematic analysis with the interns. The project requires some commitment by the interns, so please do not apply if you don’t have the time to read, write, attend meetings, and prepare presentations.

10. Understanding what makes quantum circuits difficult to simulate on classical machines
Mentor: Rajiv Krishnakumar (Goldman Sachs)
Interns: Ashish Arya, Beng Yee Gan, Lutfa Rahman, Leyla Rami, Sri Sowmya Tirukkovalluri
Project description: Typically when asked what is the reason quantum computers have a potential advantage over classical computers, most people (including myself) say that the concept of entanglement, which is unique to quantum systems, is a key component. However the Gottesman-Knill theorem proves that certain quantum circuits called “stabilizer circuits”, even some that produce highly entangled states, can be efficiently simulated on a classical computer. Another way of looking at these circuits is that they produce states with positive Wigner functions. Understanding the intuition behind what makes stabilizer circuits and positive Wigner function states easy to simulate (even those that lead to highly entangled states) can be useful in the path towards understanding what quantum algorithms could or couldn’t provide an advantage. As a first step, it would be useful to simulate very simple stabilizer circuits with classical (or probabilistic) circuits, to start to build some intuition. Then as we would like to go on to more complicated examples, we can read over the many previous works on this idea, including several papers discussing how to classically simulate these stabilizer circuits and even some software to do so. Currently, these works are phrased in the framework of understanding stabilizer circuits in the context of error correction or of creating probability distributions of positive Wigner functions. If we can then combine our intuition from the initial work with the insights from these papers/software packages, maybe we can find ways to think about stabilizers in terms of just purely classical simulations in a general and simpler way. This can either be in the theoretical direction, or in a more practical sense of implementing classical circuits/algorithms.

Project description: QAOA is a well-known quantum optimization algorithm suitable for NISQ-era quantum computing. There have been attempts to solve the integer factorization problem which lies in the core of modern cryptography using variational quantum algorithms. In the scope of this project, we plan to propose a resource-efficient alternative representation for the integer factorization problem, with a particular focus on QAOA. We plan to summarize the results with an open-source code and a scientific publication.

14. Quantum Computer Simulator for HPC
Mentor: Vivek Nainwal, Aritra Sarkar (C-DAC, Delft University of Technology)
Interns: Gaurang Belekar, Bappaditya Dey, Kianoosh Kargar, Atharva Manoj Khairnar, Aman Kumar
Project description: Quantum computing is the new paradigm of computing . As practical quantum computers are still far off , using quantum computer simulator is way to learn. QSim (https://github.com/indian-institute-of-science-qc/qiskit-aakash) is one of the python based opensource quantum computer simulator which can simulate noisy quantum logic circuits using the density matrix formalism and comes as a back end to Qiskit. However it takes long time to simulate large number of quantum bits. This work proposes to explore methodologies to make the current simulator more efficient in terms of memory footprint and accelerate the simulator execution by using multiple GPU / CPU or any hybrid approaches.

15. Quantum computing using photonics
Mentor: Anindita Banerjee (Centre for Development of Advanced Computing)
Interns: Ayan Banerjee, Mohammad Bayat, Gautam Manocha, Harish Kumar Maurya, Saroj Ray
Project description: The quantum information processing and computing using photonics is an emerging area of realizing computation which has impactful success stories. Particularly, Gaussian Boson sampling (GBS) provides a highly efficient approach to make use of squeezed states from parametric down-conversion to solve a classically hard-to-solve sampling problem. A quantum manager will finally translate a problem to algorithm and would want to implement on such devices. We make an attempt to understand the simulator (if available) for such devices and discuss the challenges and opportunities for potential quantum applications using photonics quantum processor. We also delve into the problem of which kind of problem statements / hybrid algorithm would need quantum optical processor or is it not required at all. In this project we explore these aspects.

16. Quantum Snake Game
Mentor: Kamil Hendzel (Quantumz.io Sp. z o.o.)
Interns: Linh Nguyen
Project description: The idea is to map Hamiltonian cycles onto the Ising spin-glass models, solve them with quantum annealers, and them incorporate solutions to play the classic snake game.

17. Protein Folding using Quantum Computer
Mentor: V Raghavendra ()
Interns: Buvan Prajwal A, Rea Bitri, Aparna Gupta, Durgesh Jha, Darshil Kikani, Taurean Lee, Priyanka Pandwar, Nikhil Sharma, Prashik Somkuwar, Shivesh Upadhyay, Malihe Yadavar
Project description: Understanding the nature of folding of macromolecules like proteins, DNA and RNA is central to the problems in the fields of molecular bio-physics/chemistry, bioinformatics etc. Predicting the 3D structures of proteins is of paramount significance for efficient drug discovery, medicine, crop production and other biotechnology based applications. Although conventional methods make use of classical molecular modeling techniques such as molecular dynamics to understand the protein folding problem, the classical approach has its own limitations and the problem becomes almost intractable for real life macromolecules. With the onset of quantum revolution, we aim to use the state-of-the-art quantum computer and coarse grained based technique to efficiently predict the 3D structure of the proteins.

18. Plant leaf disease detection using quantum variable neural network
Mentor: Jaykumar Lachure, Sagar Lachure (National Institute of Technology Raipur)
Interns: Reem Abdel-Salam, Rabab Azeem, Soham Bopardikar, Akash Dhingra, Ahmed Hajjem, Balusu Bhanu Prakash, Christian Lian Paulo Perez Rioflorido
Project description: First need to convert image data into quantum data through quantum circuit with minimum quantum gates. Then design of quantum variable neural network or hybrid quantum with classical architecture. Then feeding this to classify the disease types.

19. Resource-tailored multi-controlled NOT implementation
Mentor: Adam Glos, Özlem Salehi (Algorithmiq; Institute of Theoretical and Applied Informatics, Polish Academy of Sciences)
Interns: Shraddha Shankar Aangiras, Ankit Khandelwal, Handy Kurniawan, Maha Haj Meftah, Rutvij Menavlikar, Owais Ishtiaq Siddiqui
Project description: During our studies, we noticed a severe lack of good review of Multi-controlled NOT implementations. So far in the literature, multiple decompositions can be found, tailored to a different number of ancilla qubits and/or different hardware connectivity graphs. This is particularly important as the gate is frequently used in many algorithms. The principal purpose is to review the existing implementations, implement them using the qiskit programming language, and at the top of it, write a wrapper that chooses the best implementation given the size of the gate and the pre-specified resources allowed. In case of high-quality implementation, we plan to conclude it within an open-source package and possibly a scientific paper.

20. Designing a 20-Qubit Flip-chip Superconducting Processor
Mentor: Abeer Vaishnav, Nilay Awasthi (AiQyaM, Duke University, University of Pennsylvania)
Interns: Amal Alzamel, Bao Bach, Jeongwon Kim, Fabiola Cañete Leyva
Project description: This project deals with designing a 20-qubit flip-chip superconducting processor from scratch using open-source quantum hardware design tools like Qiskit Metal, KQCircuits, and SCQubits. This will involve designing custom quantum components consisting of different types of qubits, resonators, couplers, and other necessary structures to realise the full design. The design will also be optimized and tuned using various available methods involving concepts from circuit Quantum Electrodynamics (cQED), circuit quantisation and quantum analyses, to ensure optimal performance in the real-world and to make it fabrication-ready.
