Superchiral Field, Phase Modulation, Optical Cloaking

Joseph Choi, University of Rochester

Quantum mechanical or classical interactions between light and matter can demonstrate interesting effects even in simplified models. I will present three such works. The first is a semi-classical theory that corrects the enhancement from a "superchiral" field, by including the magnetic susceptibility term which is usually ignored because of how small it is.

Extended nonlocal games from quantum-classical

Vincent Russo, IQC

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.

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.

Perfect embezzlement of entanglement

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.

Practical continuous variable quantum communication in fibre and free space systems

Christoph Marquardt, Max Planck Institute for the Science of Light

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.

Metal-oxide-semiconductor (MOS) Si quantum dots

Greg Holloway, IQC

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.
