Quantum shape effects by Dr. Alhun Aydın

Tuesday, November 23, 2021 (19:00 CET) | Organized by QWorld
Moderator: Zeki Seskir (QWorld & QTurkey) and Dr. Onur Pusuluk (QTurkey)

Registration form >>

From Alhun:
Can one change the shape of a domain without changing its sizes? What might such a change in the physical properties of confined systems lead to at the quantum scales? In this talk, I’ll present my PhD thesis topic where we introduced a new type of physical effect called “quantum shape effect”. In particular, our primary focus will be on the thermodynamic properties of nanoscale systems. We show that shape becomes an independent thermodynamic state variable and as a consequence we observe many interesting thermodynamic behaviors. I’ll finally mention some of the applications of the effect such as thermoshape voltage, quantum shape oscillations and heat engines driven by quantum shape effect.

About Alhun:
Dr. Alhun Aydın works as a postdoctoral researcher in the Heller Group at Harvard University, USA. Alhun obtained his BSc in Physics at Koç University and his PhD at Istanbul Technical University, Energy Institute. During his PhD, he spent a year as a visiting researcher in the Department of Physics, Uppsala University, Sweden and Institute of Chemistry, Hebrew University, Israel. He worked on statistical thermodynamics of quantum systems, nanoscale energy conversion and quantum transport. His current research is focused on the development of coherent state representation for lattice vibrations and electron coherence effects.

Ethical Quantum Computing: A Roadmap by Elija Perrier

Thursday, March 11, 2021 (11:00 CET) | Organized by QWorld
Moderator: Zeki Seskir (QWorld & QTurkey)

See the recordings of the event on YouTube >>

From Elija:
Quantum computing is among the most significant technologies to emerge in recent decades, offering the promise of paradigm-shifting computational capacity with significant ethical consequences. On a technical level, the unique features of quantum computation have technical consequences for the imposition of fairness and ethical criteria on computation. Despite its significance, little if no structured research has been undertaken into the ethical implications of quantum technologies. In this study, we fill this gap in the literature by presenting the first roadmap for ethical quantum computing setting out prospective research programmes. In doing so, we inaugurate the cross-disciplinary field of the ethics of quantum computing.

About Elija:
Elija Perrier is a doctoral candidate at the Centre for Quantum Software and Information at the University of Technology Sydney. Elija’s doctoral research focuses on the field of quantum machine learning, including quantum algorithm design, geometric and statistical learning theory and quantum control. He has a multi-disciplinary background, holding an LLB / BA (Hons) (English/Cultural & Communication Studies) from Murdoch University along with a BSc (Physics/Mathematics) (Hons) & BA (Economics/Philosophy) from the University of Sydney.

QTalk in Pakistan
Unlimited non-causal correlations and its relation to non-locality by Amin Shiraz Gilani

Wednesday, January 20, 2021, at 20:00 Pakistan time (15:00 GMT) | Organized by QPakistan
Moderator: Jibran Rashid

See the recordings of the event on YouTube >>

From Amin:
The traditional notion of causal order dictates that a space-time event cannot influence any event in its past. There exist motivations to relax this notion from the quest to combine general relativity with quantum theory. This has led to the search for physical principles that re-establish causal order. We ask whether causal order arises in the limit of multi-particle correlations and find multi-party non-causal correlations for any number of parties that are in agreement with all principles thus far posed. However, these correlations violate a family of causal inequality maximally, while under the assumption of causal order the corresponding game can at most be won with probability half in the limit of the number of parties. This implies that the space of logically consistent correlations is infinitely larger than the space of correlations based on the assumptions of causal order. The game is closely related to Ardehali-Svetlichny nonlocal game. We leave open the search for reasonable principles that establish causal order. It seems that as of today, the only way to establish causal order is to assume it.

About Amin:
Amin Shiraz Gilani is currently a computer science graduate student at the University of Maryland – College Park. In his internship with Dr. Ämin Baumeler at the Institute of Quantum Optics and Quantum Information, he explored the fundamental nature of noncausal correlations and their relation to nonlocality. He has presented his research at QIP 2018 and 2020, the latter earning him a best poster award.

QTalks about Quantum Games

Saturday, December 12, 2020 | Organized by QTurkey

15:00 (GMT+1)
Quantum Game and other science-based games by Piotr Migdał

From Piotr:
Quantum Game with Photons is a puzzle game simulating an optical table. You can interact with superposition, entanglement, measurement, and other quantum phenomena with a LEGO bricks-like interface. I will mention Explorable Explanations and other science-based games related to other aspects of physics or computing. The main goal is to inspire YOU to make YOUR own quantum game. I will share some resources that may be inspiring or directly used to create your game (even if it is your first game).

16:00 (GMT+1)
Gamifying Quantum Computation by Cheshta Joshi & Shreyas Nisal

From Cheshta and Shreyas:
Entry into quantum computing is often daunting. We move from classical computers which work on zeros and ones to quantum computers, where quantum-bits can be in superpositions (mixtures) of zeros and ones, and where these bits can become correlated to each other. To simplify understanding these phenomena and to understand logic gates used in quantum computers, we developed QLogic, a puzzle game based on quantum computing.

17:00 (GMT+1)
Quantum Odyssey – a video game that immerse you in Quantum Computing by Laurentiu Nita

From Laurentiu:
Quantum Odyssey is first, a video game. The player does not need to know any math, physics or anything about computation or quantum; or even be a fan of quantum computation (it can be played just for the fun of solving a new type of a puzzle game).
The odyssey starts by discovering bits, linear algebra, complex numbers, qubits, all quantum phenomenon and important algorithms. By the end of the playthrough, the Player will have all the “hacker tools” needed to design their own algorithms, understand papers on Universal Quantum Computing and create their own or find more efficient dozens of gates long quantum algorithms.

QTalk in Latvia | Quantum supremacy by Janos Asboth

Perhaps the most important recent milestone in the exciting progress of quantum computing was passed last year, with the achievement of quantum supremacy by the UCSB-Google group. I was as excited to hear of this result as any of us working in the field of quantum information. I will discuss what quantum supremacy means, how it was demonstrated by Google’s group, and how this fits into the pattern of progress of quantum computing.
Disclaimer: I am not associated with Google, and did not take part in the experiment.

About Janos:
Janos Asboth is associate professor at the Budapest University of Technology and Economics, and Senior Research Fellow at the Wigner Research Centre for Physics in Budapest.

Light is an electromagnetic wave. One of its key properties is polarization – the axis of oscillations. This phenomenon is used in photography, LCD screens, and quantum information. We will perform virtual experiments on how does the polarization interacts with mirrors, sugar solution, or magnetic field. All experiments in the Quantum Game virtual lab: https://quantumgame.io/

‬19:00 (GMT+3), Thursday, October 22, 2020 | Organized by QLatvia
Moderators: Viktorija Laimane & Krista Petersone

From Laura:
“In this talk, I will share my professional journey into the strange world of quantum superposition and entanglement, where two friends, Alice and Bob, might even appear to have telepathic powers. It all began with a research seminar led by Prof. Rūsiņš Freivalds at the University of Latvia and continued with graduate studies and researcher appointments at various quantum computing centers across the globe. I will talk about what it takes to be a researcher and why I find the area of quantum computing particularly exciting. We will also see how simple games can be used to understand the power and limitations of quantum entanglement and even test proper functioning of quantum devices.”
