### Wavelength selective thermal emitters using nitride quantum wells and photonic crystals

#### Dr. Dongyeon Daniel Kang, Kyoto University

Wavelength selective thermal emitters are highly desired for the development of the compact/energy-efficient spectroscopic sensing systems capable of detecting various gases such as COx, CH4, and NOx, which are strongly needed in environmental science, medical care, and other industrial applications. In addition, for the latter applications, dynamic control of thermal emission intensity is important for such emitters because synchronous detection can increase the signal-to-noise ratio significantly.

## Applied Mathematics Colloquium: Quantum Universe

### Neil Turok, Perimeter Institute

Observations reveal the cosmos to be astonishingly simple, and yet deeply puzzling, on the largest accessible scales. Why is it so nearly symmetrical? Why is there a cosmological constant (or dark energy) and what fixes its value? How did everything we see emerge from a singular “point” in the past?

## Quantum Algorithms for Composed Functions With Shared Inputs

### Justin Thaler, Georgetown University

The quantum query complexity of a function f measures how many bits of the input a quantum computer must look at in order to compute f.

## PhD Seminar • Quantum computing / quantum information - self embezzlement using C*-dynamics

### Li Liu

Following my previous seminar talk on embezzlement of entanglement, this talk introduces a more general version of the problem — self-embezzlement. Instead of embezzling a pair of entangled state from a catalyst, self-embezzlement aims to create two copies of the catalyst state using only local operators.

## Steeped Thoughts: Feminism as Material and Method

What does it mean to ask feminist questions of the worlds we study?

Join Aryn Martin from York University in a talk about addressing this question and whether having more women in science is the same as having more feminism in science.

## PhD Seminar • Quantum resistance of the cryptography used in trusted-execution environments

### Dhinakaran Vinayagamurthy

Trusted-execution environments (TEE) like Intel SGX provide a promise for practical secure computations on users' sensitive data in untrusted computing environments like cloud and blockchains. TEEs are designed using a combination of hardware enforced access controls and cryptography. While there is extensive research on attacking and hardening the access control mechanisms, the advent of quantum computers also requires hardening the cryptography used by TEEs for their long-term security against quantum adversaries.

## Using macroscopic quantum systems as detectors

### Swati Singh, University of Delaware

When properly engineered, simple quantum systems such as harmonic oscillators or spins can be excellent detectors of feeble forces and fields. Following a general introduction to this fast growing area of research I will focus on two simple and experimentally realizable examples: a nitrogen vacancy (NV) center in diamond interacting with its many-body environment, and acoustic modes of superfluid helium interacting with gravitational waves.

## Dynamical control of superconductors and ultracold atoms

### Ludwig Mathey, University of Hamburg

## PhD Seminar • Perfect embezzlement of entanglement

### Li Liu

Entanglement is a type of resource used in quantum information theory that gives correlations that cannot be simulated using classical probability theory. It is known that entanglement cannot be created locally.

## RAC1 Journal Club/Seminar Series

### Neutron whispering gallery

#### Dr Valery Nesvizhevsky, European Centre for Neutron Research, Institut Laue-Langevin

The "whispering gallery" effect has been known since ancient times for sound waves in air, later in water and more recently for a broad range of electromagnetic waves: radio, optics, Roentgen and so on. It consists of wave localization near a curved reflecting surface and is expected for waves of various natures, for instance, for atoms and neutrons. For matter waves, it would include a new feature: a massive particle would be settled in quantum states, with parameters depending on its mass. In 2010, we observed the quantum whispering gallery effect for cold neutrons and since then continue increasing the precision in these experiments.

## Quantum proof systems for iterated exponential time, and beyond

### Henry Yuen, University of Toronto

An outstanding open question in quantum information theory concerns the computational complexity of nonlocal games. in a nonlocal game, a classical verifier interacts with multiple players that cannot communicate, but are allowed to share entanglement. In a recent breakthrough result, Slofstra showed that the following problem is undecidable: given a nonlocal game, is there a quantum strategy for the players to win with probability 1?

## Entangled: The series

### QUANTUM + Pop Culture

“Quantum physics” has taken its position with “rocket science” in pop culture as a shorthand for frighteningly complicated science. Quantum physics has also taken on a sort of magical connotation in fiction, with features like entanglement, superposition, and tunneling spurring imagination. But where does the science draw the line? How much is joyful speculation, and how much is disregard for reality? And if it’s always seen as either magical or scary, how does that affect the perception of quantum science?

## On Stephen Hawking

#### Raymond Laflamme, Department of Physics and Astronomy; Institute for Quantum Computing

Stephen Hawking passed away leaving behind a transformed view of the cosmos. He proved that time had a beginning if Einstein's general relativity is correct, that black ain't so black after all and he proposed that the Universe can be described by a quantum mechanical wave function with no edge or boundaries. From 1984 to 1988 I was one of Stephen's graduate students and worked on quantum cosmology and the arrow of time which earned me a quote in the book: "A Brief History of Time".
