Nonlocality is a useful quantum resource in applications such as quantum key distribution and quantum random number generation. We study nonlocality in a multi-qubit model—quantum kicked top (QKT). This system is of particular interest because it displays regular behavior, bifurcations and chaotic behavior in the classical limit, and is one of the few chaotic systems that has been experimentally realized.

Co-organized by the National Research Council of Canada 

The meeting brings together the Canadian community of scientists and engineers who perform research and development on spin-based quantum technologies. This will be the third annual workshop, with the main goal to foster spin qubit research and attract and train highly qualified personnel for the emerging quantum technologies sector in Canada.

We present two concrete examples where the Renyi rather than just the von Neumann entanglement entropy is necessary in order to obtain certain insights into quantum many-body systems.

One-out-of-two (1-2) oblivious transfer is a cryptographic primitive, in which a sender holds two bits, x0 and x1, and a receiver receives one of them, in such a way that the receiver does not know both bits, and the sender does not know which bit the receiver obtained. While information-theoretical security for quantum versions of such protocols is not possible, it is of interest to examine possible security bounds, which previous work has shown to be set at 0.749 in “complete” protocols employing pure symmetric states.

Designing control pulses to generate desired unitary evolution subjugated to experimental constraints (e.g., decoherence time, bandwidth) is a common task for quantum platforms, these type of problems are often addressed in the context of quantum optimal control. Parallel Automatic Differentiation Quantum Optimal Control (PADQOC) is an open-source, Python based general quantum optimal control solver built on top of Tensorflow 2. It is designed to be fast, extensible and useful for controlling general quantum systems.

Much of our intuition about light comes from our experience that light has very weak interaction with other light—a beam of light easily passes through another beam of light, so that the Star Wars scenes of “light sabers” bouncing off each other are just imaginary. But in solids, the properties of light can be changed dramatically, especially in solids that we design for new effects.

Security in the Quantum Future

Quantum theory is quickly becoming quantum technology.

Abstract: 

The Quantum Innovators in Computer Science and Mathematics workshop brings together promising researchers working on theoretical aspects of quantum information and computation in computer science and mathematics. 

Talks are open for anyone to attend.

Due to the APS March Meeting being canceled, IQC has scheduled a mini-symposium for University of Waterloo students to give their accepted talks.

Talks are open for all to attend.
