Prof. Cheng Chin: "The unexpected observation of Bose fireworks"

Weekly seminar

03 Dec 2020

16:30

To the recorded seminar: Experiments come with surprises. In this talk, I will describe the story behind the discovery of Bose fireworks, a sudden emission of matterwave jets from a periodic Bose-Einstein condensate.

Prof. Alexey Gorshkov: "Dynamics of quantum systems with long-range interactions"

Weekly seminar

19 Nov 2020

16:30

To the recorded seminar Atomic, molecular, and optical systems often exhibit long-range interactions, which decay with distance r as a power law 1/r^alpha. In this talk, we will discuss bounds on how quickly quantum information can propagate in such systems.

Dr. Assaf Hamo: "Imaging phonon-mediated hydrodynamic flow in WTe2 with cryogenic quantum magnetometry"

Weekly seminar

05 Nov 2020

16:00

To the recorded seminar In the presence of strong interactions, electrons in condensed matter systems can behave hydrodynamically thereby exhibiting classical fluid phenomena such as vortices and Poiseuille flow. While in most conductors large screening effects minimize electron-electron interact

Prof. Steve Simon: "Topologically Ordered Matter and Why You Should be Interested"

Weekly seminar

29 Oct 2020

14:30

In two dimensional topologically ordered matter, processes depend on gross topology rather than detailed geometry.

Prof. Renato Renner: "Optimal universal programming of unitary gates"

Weekly seminar

22 Oct 2020

14:30

To the recorded seminar The “No-Programming Theorem” asserts that perfect universal quantum processors cannot exist. These are hypothetical devices that execute a unitary gate that is choosable arbitrarily and itself provided as a (quantum) input.

An introduction to the Julia programming language: with examples for simulating quantum systems.

Seminar

17:10

Over the last couple of years, the Julia programming language has grown in popularity, recently even replacing C and Python in undergrad classes at MIT. Julia is a high-performance language (considered "as fast as C"), yet is also a high level, script language (that feels "like Python").

Prof. David Gosset: "Fast simulation of planar Clifford circuits"

Weekly seminar

01 Oct 2020

14:30

A general quantum circuit can be simulated in exponential time on a classical computer. If the circuit has a planar layout, then a tensor-network contraction algorithm due to Markov and Shi has a runtime exponential in the square root of its size, or more generally exponential in the treewidth of the underlying graph.

Dr. Yuval Ronen: "Fabry–Pérot quantum Hall interferometry in graphene"

Weekly seminar

24 Sep 2020

14:30

Chiral, one-dimensional (1D) edge channels in the quantum Hall (QH) effect guide electrons dissipationless. Using quantum point contacts (QPCs) as beamsplitters, these 1D channels can be split and recombined, enabling interference of propagating electron wave functions.

Prof. Simon Benjamin: "Quantum algorithms and architectures for the NISQ era: Can they really work?"

Weekly seminar

17 Sep 2020

14:30

In this talk I will offer an overview of my Oxford group’s recent work targetting NISQ (noisy intermediate scale quantum) devices. This is an area of tremendous interest at the moment as we are starting to see quantum devices at, or beyond, the practical limits of simulation power of today’s supercomputers. But of course the ability to build a machine that a conventional computer cannot simulate may be a long way from building something useful!

How does light propagate in integrated circuits on chips?

Researchers at the Technion are answering this question and paving the way to new applications in communication, imaging, and quantum computing. The field of photonic integrated circuits focuses on the miniaturization of photonic elements and their integration in photonic chips – circuits that carry out a range of calculations using..

Yuval Shagam won an ERC grant

Assistant Professor Yuval Shagam from the Schulich Faculty of Chemistry is a member of the Helen Diller Quantum Center. He focuses on understanding molecular chirality: a molecule or ion that cannot be superposed on its mirror image. Such molecules are often distinguished as either “right-handed” or “left-handed.” Molecular chirality plays a central role in many fields, ranging from reaction dynamics to drug development. Molecules of opposite-handedness, known as enantiomers, can have different smells and different medicinal properties among other things.

Toward the discovery of new quantum phenomena that have yet to be observed: Prof. Ido Kaminer of the Technion won an ERC Consolidator grant

Prof. Ido Kaminer of the Viterbi Faculty of Electrical and Computer Engineering won an ERC Consolidator grant from the European Research Council.ERC Consolidator grants support select scientists who propose pioneering, ground-breaking research ideas. The grant will be used by Prof. Kaminer’s research team to develop a theory and innovative experimental platform for a new field in electron microscopy: Q-in-PINEM. The research will focus on creating new quantum states and identifying unique quantum properties for materials.

Atomic-scale spin-optical laser: new horizon for optoelectronics

Researchers from the Technion have pushed the limits of the possible in the field of atomic-scale spin-optics, creating a spin-optical laser from monolayer-integrated spin-valley microcavities without requiring magnetic fields or cryogenic temperatures

The physical world through the lens of computational complexity

“Computers are physical systems, and so are our brains. Therefore, they are subject to physical laws that determine what they can and cannot calculate,” points out Prof. Itai Arad, a theoretical physicist who researches the field of quantum information. He is determined to better understand physical systems by drawing on tools and insights from a variety of disciplines – including condensed matter physics, information theory, computer science and statistical mechanics. Specifically, Prof.
