What is quantum? Join us for the Qubit Club at THEMUSEUM to learn all about quantum with some fun and exciting science demonstrations!
Several variants of nonlocal games have been considered in the study of quantum entanglement and nonlocality. In this talk, we shall consider two such variants called quantum-classical games and extended nonlocal games. The players, Alice and Bob, may play the game according to various classes of strategies. An entangled strategy is one in which Alice and Bob use quantum resources in the form of a shared quantum state and sets of measurements. One may ask whether the dimension of the shared state makes a difference in how well the players can perform using an entangled strategy.
Come get your nerd on and learn about the world of physics with Nerd Nite KW! They will take you through quantum 101, and then see if you were paying attention with some friendly rounds of trivia. Aspiring scientists and experts alike are welcome. Special guest speaker Dr. Shohini Ghose, an Associate Professor of Physics and Computer Science and Director of the Centre for Women in Science at Wilfrid Laurier University in Canada, will also be giving a presentation. Make sure to also check out QUANTUM: The Exhibition while you're there.
The Quantum Innovators workshop brings together the most promising young researchers in quantum physics and engineering. Guests are invited for a four-day workshop aimed at exploring the frontier of our field.
Van Dam and Hayden introduced the concept of approximate embezzlement of entanglement. Even if one allows infinite dimensional resource spaces but requires a bipartite tensor product structure of the resource space, perfect embezzlement is still impossible. But in the commuting operator framework perfect embezzlement is possible. We then introduce unitary correlation sets and relate these ideas to the conjectures of Connes and Tsirelson.
I will review our recent activities in continuous variable QKD that aims for the deployment of QKD equipment compatible with current telecom standards and research in satellite QKD that will make it possible to bridge long distances. In optical fibre systems continuous variable quantum cryptography reaches GHz speed and offers efficient integration with known telecommunication techniques, especially in short inner-city or data center links. Sending and receiving components, including quantum random number generators, can be efficiently built in integrated components. Optical free space communication is a reliable means to transmit classical and quantum information. Free space links offer ad-hoc establishment in intra-city communication, air-to-ground or satellite-to-ground scenarios.
Electrostatically defined quantum dots provide a flexible implementation for scalable spin-based quantum information processing. Recently Si has emerged as a promising platform for these systems, due to its long electron spin coherence times, and its compatibility with numerous fabrication processes. In this talk I will give a detailed description of the device architecture, as well as a description of transport through Si quantum dots.
If you're coming from the Lazaridis Centre, take the 11:35am shuttle from QNC to RAC1, and they can return to QNC from RAC1 @ 1:15pm.
A light lunch will be provided.
Quantum error correction presents some of the most significant and interesting challenges that must be resolved before building an efficient quantum computer. Quantum error correcting codes allow to successfully run quantum algorithms on unreliable quantum hardware. Because quantum hardware suffers from errors such as decoherence, leakage or qubit loss, and these errors corrupt delicate quantum states rather than binary information, the known error correction techniques are complex and have a high overhead.
The quantum data processing inequality (equivalently, the strong sub-additivity of von Neumann entropy) is a cornerstone of quantum information theory. It has been proven in numerous ways, each proof highlighting different aspects of the property.
