QIntern is the summer internship program of the QWorld Association, hosted by the QResearch Department. The goal of QIntern is to encourage and support collaborative work in quantum information science and technology, bringing together more experienced people (mentors) and those willing to learn more (interns).

In case of successful application, each intern is assigned to a project and gets involved into developing new software, education materials, or research results. The scope of the projects is broad and the mentors represent different areas of research and practice in the quantum world. Some internships may result in longer collaborations. 

Your summer at QWorld 

QIntern 2021 will be a seven-weeks program from July 1 till August 22.

As an intern, you will work remotely under supervision of a mentor. QWorld will provide the organizational support and communication platforms. Your internship will be an individual or a group project, depending on the topic and preferred mode of collaboration. 

In addition to acquiring new skills and professional experience, you will meet other interns and get acquainted with the QWorld community. QIntern2021 is a program that will help you find the right way into the quantum ecosystem.

3. Chaotic non-linear maps in entanglement distillation protocols

Mentor: Aurél Gábris (Czech Technical University in Prague)

Project description: Theoretical protocols for distilling maximally entangled pairs of qubits are a well-studied cornerstone of quantum communication. In our previous works we have shown that true complex chaos naturally arises in these protocols. The scope of the internship project would be to explore the properties of non-linear maps that arise in protocols involving entanglement in higher qudit states. The outcome of these studies may be interesting from practical point of view in certain optical quantum communication implementations. 

4. Theory of qubit readout

Mentor: Andras Palyi (Budapest University of Technology and Economics)

Interns: R K Rupesh, Zoltán Guba

Project description: Understanding the readout process in qubit experiments is a critical task, especially in the context of quantum error correction. The goal of this project is to set up and investigate physical models describing the readout process of specific qubit realizations. We will focus on semiconductor-based qubits, e.g., charge, spin and Majorana qubits.  

5. Coherent errors in surface code

Mentor: Janos Asboth (Budapest University of Technology and Economics)

Interns: Nikhil Londhe, Áron Márton

Project description: We aim to simulate numerically the effect of coherent errors on the surface code, using Fermionic Linear Optics as described by Bravyi et al [npj Quant. Inf. (2018)4:55]. This summer research project is to understand the theoretical approach, to reproduce the results of Bravyi et al, and to apply this formalism to a slightly different error model.  

6. Surface Code design for asymmetric error channel

Mentor: Ritajit Majumdar, Debasmita Bhoumik (Indian Statistical Institute)

Interns: Aleksandra Lipińska, Rijul Sachdeva, Shilpa Mahato, Utkarsh Azad

Project description: Recent roadmaps of research industries such as IBM, Google, IONQ etc. claim that a few error corrected logical qubits is at hand in next few years. All of these industries are looking into surface code for the error correction purpose, since this code requires interaction between adjacent qubits only, and hence is highly suitable for the current planar quantum architecture. A surface code is symmetric, i.e., it can correct an equal number of X and Z errors. However, in real world quantum channels, Z errors are much more probable (~100 times) than X errors. This has motivated many research on asymmetric error correcting codes, where the code can correct more Z errors than X errors. But such a study for surface code is not available yet. In this project, we shall design a surface code that can correct a single X error and two Z errors. We shall find the number of qubits required to design one logical qubit using such an asymmetric surface code, show the underlying circuit, and define the logical operators. Finally, we shall mathematically provide a lower bound on the number of qubits required to design a surface code which can correct upto tx X errors and tz Z errors.  

7. Quantum Computing with Spiders (ZX Calculus)

Mentor: Srinjoy Ganguly, Gopika Rao Chaganti (AdroitERA (AERA))

8. Quantum Natural Language Processing with DisCoPy

Mentor: Srinjoy Ganguly, Gopika Rao Chaganti (AdroitERA (AERA))

Interns: Antonio Jesús García Palomo, Avhijit Nair, Meriem Kasmi, Pooja M Hiremath

Project description: Quantum Natural Language Processing (QNLP) is an emerging field of research where we identify natural language to be quantum native and use the category theoretic and diagrammatic reasoning to perform natural language processing on quantum computers by translating sentences and meanings into quantum circuits. The work in this internship will involve developing intuitive and simple educational materials of category theory, diagrammatic reasoning and then making simple study materials for QNLP. Also apart from developing materials, interns would also have to develop code tutorials and code documentation for the QNLP library DisCoPy and t|ket> 

9. Sequential sharing of quantum resource of a single copy.

Mentor: Shashank Gupta (S. N. Bose National Centre for Basic Sciences)

Interns: Freya Shah, Hariprasad M, Yash Wath

Project description: We will investigate the possibility of multiple use of a single copy of a bipartite or multipartite quantum states for quantum resource contained in the state. A sequence of multiple observers perform unsharp or non-projective measurements acting independently of each other such that some quantum resource is left for the next observer. The choice of measurement settings for each sequence is independent and uncorrelated with the measurement settings and outcomes of the previous observers. The motivation is to obtain an upper limit on the number of observers that can share a quantum resource. This work will provide an efficient usage of the quantum resource and will be useful in secret sharing, security of quantum networks (if Eve eavesdropping is also non-projective or unsharp).
