Elkouss: Analysis of a rate-adaptive reconciliation protocol

David Elkouss, Universidad Complutense de Madrid

"Quantum key distribution performs the trick of growing a secret key in two distant places connected by a quantum channel. In practical systems, whether because of finite resources or external conditions, the quantum channel is subject to fluctuations. A rate adaptive information reconciliation protocol, that adapts to the changes in the communication channel, is then required to minimize the leakage of information in the classical postprocessing.

Undergraduate School on Experimental Quantum Information Processing (USEQIP)

The Undergraduate School on Experimental Quantum Information Processing (USEQIP) is a two-week program on the theoretical and experimental study of quantum information aimed primarily at students completing their third undergraduate year. The lectures and experiments are geared toward students in engineering, physics, chemistry, mathematics and computer science, though all interested students are invited to apply.

Xiaodong Xu: Spin and pseudospins in 2D semiconductors

Xiaodong Xu, The University of Washington

Electronic valleys are extrema of Bloch energy bands in momentum space. Having multiple valleys gives the electron states pseudospin degrees of freedom in addition to their real spin. In this talk, I will discuss our experimental progress on the investigation of spins and pseudospins using atomically thin semiconductors, which are either single or bilayer group VI transition metal dichalcogenides.

Gharibian: Ground state connectivity of local Hamiltonians

Sevag Gharibian, University of California, Berkeley

The study of ground spaces of local Hamiltonians is a fundamental task
in condensed matter physics. In terms of computational complexity
theory, a common focus in this area has been to estimate a given
Hamiltonian’s ground state energy. However, from a physics
perspective, it is often more relevant to understand the structure of
the ground space itself. In this paper, we pursue the latter direction
by introducing the notion of “ground state connectivity” of local

Quantum technologies are widely expected to bring about many key technological advances this century. Quantum metrology and quantum information have been so far successfully applied in the design of devices that outperform their classical counterparts by exploiting quantum properties. Impressively, the quantum era is now reaching relativistic regimes. Table-top experiments demonstrate relativistic effects in quantum fields and long range quantum experiments will soon reach regimes where relativity kicks in.

Laura Mancinska, Centre for Quantum Technologies, Singapore

Quantum entanglement is known to provide a strong advantage in many two-party distributed tasks. We investigate the question of how much entanglement is needed to reach optimal performance. For the first time we show that there exists a purely classical scenario for which no finite amount of entanglement suffices. To this end we introduce a simple two-party nonlocal game $H$, inspired by Hardy's paradox. In our game each player has only two possible questions and can provide bit strings of any finite length as answer.

Miller: Quantum random number generation from untrusted devices

Carl A. Miller, University of Michigan, Ann Arbor, USA

Recently Yaoyun Shi and I gave the first proof of security for robust exponential quantum randomness expansion. This talk will be an overview of the problem and a discussion of the techniques used in our proof.

Quantum Industry Lecture Series: Phil Kaye, Government of Canada

The lecturer will be Phil Kaye, a 2006 IQC graduate currently working at the Government of Canada. This lecture will be more informal and will focus on Phil's career path, how his PhD prepared him for his current position, and the challenges of working outside of academia.

For futher questions, please contact Corey Rae, IQC GSA President, crmcrae@uwaterloo.ca

Kuntz: Quantum non-Gaussian and Gaussian States at Multiple Side-band Frequencies

Katanya Kuntz,  University of New South Wales, Canberra, Australia

We simultaneously generate photon-subtracted squeezed vacuum and squeezed vacuum at three frequencies from an optical parametric oscillator by utilizing its frequency non-degenerate sidebands. Quantum non-Gaussianity is demonstrated by applying a novel character witness.
