  2. Microgrant program of Unitary Fund by Sarah Kaiser
    See the recording on YouTube >>
  3. Five term-project presentations by students:

Develop your career, skills, and quantum technologies with Unitary Fund
Near-term quantum error mitigation (QEM) is quite an active area of research and as a group we wished to explore. The quantum technology ecosystem is growing fast and heavily invested in open source projects. Developing and and maintaining these projects are amazing opportunities for personal and professional growth, as well as pushing the boundaries of what these new devices can do. Unitary Fund supports this community by providing microgrants to support open quantum projects, as well as building a community of peers and mentors to help explorers develop quantum technologies. I want to share with you a bit about what we do at Unitary Fund and how you can get involved working (and getting paid!) in quantum open source.

Dr. Sarah is currently a technical staff member and quantum community lead at Unitary Fund, a non-profit working on building the quantum open source community. She has spent much of her career developing new quantum hardware in the lab, from building satellites to hacking quantum cryptography hardware and VR technology. Communicating what is so exciting about quantum technology is her passion, and loves building new demos, tools, and partnerships to help enable the quantum community to grow. When not at the keyboard she loves kayaking, laser cutting everything (safe), and writing books about engineering for kids and adults alike.

Benchmarking Error Mitigation Techniques by Tuńüba √Ėzbilgin & Amir Ebrahimi
Near-term quantum error mitigation (QEM) is quite an active area of research and as a group we wished to explore how good these error mitigation techniques perform. We numerically benchmarked these techniques against different noise models and in the process learned about what metrics were important to track. We made use of Mitiq, an open-source toolkit, to perform these benchmarks. The QEM techniques we used were zero-noise extrapolation, Clifford-data regression (CDR), probabilistic error cancellation (PEC), and randomized compiling (RC).

Dr. Tuńüba √Ėzbilgin is a senior researcher in the Scientific and Technological Research Council of Turkey (T√úBńįTAK). Her research interests include optical communications, optical sensors & imaging systems, quantum communications, and stochastic signal processing.

Amir Ebrahimi is a Principal Software Engineer working at Unity Technologies. He has a B.S. in Computer Science from Georgia Tech and is pursuing a M.S. in C.S. from UT Austin. Amir has worked in video games/vfx for 19+ years and is now adamantly pursuing the field of quantum computing.

Quantum automaton implementation by Aliya Khadieva
Quantum finite automata (QFAs) are a mathematical model for quantum computers with limited memory. In 1998 Freivalds and Ambainis presented a technique for construction of QFAs exponentially smaller than classical counterparts for several languages. They used a fingerprinting approach for construction of a QFA. In this project, we present an implementation of such QFAs using Qiskit library. Secondly, as an application of this algorithm, we implement a protocol using quantum digital signature.

Senior Teacher at Kazan Federal University, PhD student at University of Latvia, CS field.

Bloch duel v2 by PrzemysŇāaw MichaŇāowski & Krzysztof Kr√≥lewicz
Interactive introduction to quantum gates and measurement through a game for two.
The project is back-end for a game, where two players are changing the states of qubits using quantum gates. Their goal is to catch the qubits in a specific position using measurements. However, nothing is determined even if the point has been scored, which causes the players to think twice before they try to do something.

PrzemysŇāaw MichaŇāowski is a student of SGH Warsaw School of Economics in the field Big Data Analytics, member of QPoland and board member of SGH Student’s Association for CS. Passionate about data, programming and quantum computing.

Krzysztof Królewicz is a student at SGH Warsaw School of Economics, Big Data РData Analysis faculty. Hobbyist in Python programming, passionate about mathematics, interested in quantum computing since recently.

Introduction to Open Quantum Systems by Alvaro Rafael Gomez
I am a professional in Computer Science and Data Science. I also worked as an IBM instructor on software products.

I decided to create tutorials after seeing the excellent QBronze and QSilver teaching notebooks, as well as the excellent exercises in the self-study tests of QCourse511.

A Mathematical Introduction to Quantum Computing by Israel Gelover
Quantum Computing lies at the intersection of Physics, Mathematics, and Computer Science. In this project the first two components are explored and the theory of Quantum Computing is built upon these concepts.

Israel Gelover studied Mathematics at Universidad Nacional Autónoma de México, he works as a full time software developer and Quantum Computing is one of his main interests.

Our 20th QWebinar

Bell’s Theorem: The Surprising Magic of Quantum Correlations | 17:00 (UTC), Thursday, November 11, 2021
by Elie Wolfe (Perimeter Institute for Theoretical Physics)

Moderator: Jibran Rashid (QWorld & QPakistan)
Organizers: Agnieszka Wolska (QWorld) and Abuzer YakaryńĪlmaz (QWorld)

From Elie:

“You may have that quantum physics requires overthrowing long held classical preconceptions. Depending on who you talk to, those ruled-out preconceptions might be referring to as any combination of determinism, realism, and/or locality. But what does that really mean, and how are we certain that quantum theory is so radical? We will explore the gold-standard proof that quantum theory is truly nonclassical, namely, Bell‚Äôs theorem. John Stewart Bell discovered a clever way to characterize the set of all correlations which are consistent local hidden variable models, in terms of inequality constraints. He then showed that quantum theory makes operational predictions which violate those constraints. We will review a derivation of Bell‚Äôs inequalities, emphasizing how modern linear programming software can be used to automate the process. (Not just slides: We will do a live demonstration.) Finally, we will show that a causal interpretation of Bell‚Äôs inequalities suggests that the same algorithm can be recycled to solve superficially unrelated problems, such as evaluating the efficacy of a medical protocol from trial data with imperfect compliance. We will introduce some basic ideas about causal inference, with a spotlight on both the utility and limitations of linear programming in statistical analysis beyond quantum foundations.”

About Elie:

Elie Wolfe is the Director’s Fellow for Quantum Causal Inference at the Perimeter Institute for Theoretical Physics. He received his license as a quantum mechanic (PhD) from the University of Connecticut, where his thesis explored the theoretical limits of quantum nonlocality and contextuality. He now revisits such nonclassical phenomena though the frameworks of causal inference and research theories. He has contributed to the development of multiple pathbreaking computational algorithms and leads their open-source implementations. He encourages potential postdocs and PhD students to contact him directly.

Our 19th QWebinar

QInterns’ Talks | 16:00 (UTC), Thursday, October 21, 2021

  • Mapping the landscape of Quantum Education” by Abhishek Manhas
  • Eavesdropping a Quantum Key Distribution network” by Shashank Gupta

Moderator: Jibran Rashid (QWorld & QPakistan)
Organizers: Agnieszka Wolska (QWorld) and Abuzer YakaryńĪlmaz (QWorld)

Mapping the landscape of Quantum Education
I’m going to talk about how the field of Quantum computing is progressing due to which it has created an “Imaginary gap” between people – ones are who are already advancing in it and the ones who are new to it. Then, I’m going to discuss our QIntern’21 project where I will describe how this might help to “bridge that gap” between people. I’m also going to discuss some problems we faced and how our personal experiences can help beginners in this field, including our long-term plans for this project.

See the recordings of the event on YouTube >>

About Abhishek: I’m a high school student, who is a Number Theory and Philosophy enthusiast, interested in the collaboration of chaos theory and computer science, with a combination of psychology.

Eavesdropping a Quantum Key Distribution network
After reviewing the most celebrated quantum cryptography technology (QKD), we will discuss the popular quantum attacks on the QKD network. We investigate the possibility of eavesdropping on a quantum key distribution network by local sequential quantum unsharp measurement attacks by the eavesdropper. In particular, we will show how an eavesdropper can utilize the imperfection in the practical QKD networks by performing different kind of intercept-resend attacks.

Our 18th QWebinar

NISQ Computing | 16:00 (UTC), Thursday, October 14, 2021
by M. Sohaib Alam (University of Texas)

Moderator: Jibran Rashid (QWorld & QPakistan)
Organizers: Agnieszka Wolska (QWorld) and Abuzer YakaryńĪlmaz (QWorld)

See the recordings of the event on YouTube >>

From Sohaib:

“Although several quantum algorithms exist for ideal quantum computers with a large number of logical qubits with provable speed-ups over classical algorithms, these may not be implementable on quantum devices available at the present time or in the near future. Furthermore, the resources required to perform error correction in a fault tolerant manner may also be out of reach in the near term. With this view, in this talk we will discuss hybrid quantum/classical algorithms that are better suited for near-term devices, and discuss error mitigation techniques to improve their performance on noisy hardware.”

About Sohaib:

M. Sohaib Alam is a theoretical physicist and software developer who completed his PhD in quantum gravity from the Weinberg Theory Group at the University of Texas at Austin. He has worked as lead data scientist at Xylem, and most recently as a senior quantum applications engineer at Rigetti computing.

Our 17th QWebinar

Conservative Causality | 16:00 (UTC), Thursday, October 7, 2021
by √Ąmin Baumeler (IQOQI Vienna)

Moderator: Jibran Rashid (QWorld & QPakistan)
Organizers: Agnieszka Wolska (QWorld) and Abuzer YakaryńĪlmaz (QWorld)

See the recordings of the event on YouTube >>

From √Ąmin:

“I give an overview on the frameworks of conservative causality: Frameworks that locally conserve the standard notion of causality. These frameworks relate to quantum theory or Turing machines in the same way as general relativity relates to special relativity, and therefore, they allow for an abstract study of exotic features in general relativity and quantum gravity. Moreover, since these frameworks seem to agree with natural principles, except for causal order, they form a test bed to study the origin of causal order – a tool to address the question: How can we derive causal order without presupposing causal order?”

About √Ąmin:

√Ąmin Baumeler holds a group leader position at the Institute for Quantum Optics and Quantum Information (IQOQI Vienna) of the Austrian Academy of Sciences. He studied computer science at ETH Z√ľrich, Switzerland, and at the Institute for Quantum Computing, University of Waterloo, Canada. In 2017, he defended his PhD thesis “Causal loops: logically consistent correlations, time travel, and computation,” which was supervised by Prof. Wolf at the University of Lugano, Switzerland. For that work, he obtained the best-thesis award from the German, Swiss, and Austrian societies of computer science. From 2017 to 2019 he held a postdoc position in the group of Prof. Brukner at IQOQI Vienna.

Quantum Literacy in future education and transdisciplinary problem-solving | 16:00 (GMT), Wed, March 3, 2021
by Laurentiu Nita (Durham University)

Moderators: Zeki Seskir (QWorld&QTurkey) and √Ėzlem Salehi (QWorld&QTurkey)
Organizers: Abuzer YakaryńĪlmaz (QWorld) and Agnieszka Wolska (QWorld)

See the recording of the event on YouTube >>

From Laurentiu:

“I will present the concept of Quantum Literacy. We define it as the need to foster knowledge acquisition in the study of quantum technologies, for a broader community than those involved in the study of physics. It is increasingly important that the knowledge of quantum technologies is accessible to those who work with real world applications in a more inclusive way. We therefore argue for the importance of addressing the pedagogic issues that arise from the study of quantum technologies. These pedagogic issues arise from the dense concepts, as well as complex and hierarchical relations between concepts, in addition to strong barriers to entry in the form of mathematics. I will demonstrate how a specific puzzles-based visualization learning tool, called Quantum Odyssey, is capable to overcome these barriers and achieve these pedagogic ends with respect to quantum computation.”

About Laurentiu:

Laurentiu Nita is the founder of Quarks Interactive, the company that develops the visual learning platform called Quantum Odyssey, with the mission to foster quantum literacy in our society.

Organizers: Abuzer YakaryńĪlmaz (QWorld) and Agnieszka Wolska (QWorld)

See the recording of the event on YouTube >>

From EliŇ°ka:

“Quantum systems constitute an excellent platform to study many phenomena that are too complex to be approached otherwise. We expect the study and control of quantum matter to lead to a better understanding of a range of phenomena from complex chemical reactions to advanced nano materials. Both control and design of such quantum systems however come with many challenges due to their incredible complexity. In this talk I explain how artificial intelligence (AI) is helping us with these challenges on two examples: On one hand we can employ AI as a helper for discovery of new phases of matter, on the other it can also take over complex experimental control tasks such that our quantum devices can perform at their best.”
