Current students

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.

On the geometry of entanglement

Rotem Liss, Technion – Israel Institute of Technology

Entanglement is an important concept in quantum information and computing. In this talk, I present a simple geometrical analysis of all rank-2 quantum mixed states. The analysis is complete for all the bipartite states, and is partial for all the multipartite states.

Nonlocal Correlations between Frequency Entangled Two-Qudit States

Sacha Schwarz, University of Bern

In my talk, I will demonstrate our method to experimentally encode qudits in the energy spectrum of broadband entangled photons generated by parametric down-conversion and detected in coincidence by sum frequency generation. Employing techniques from ultrafast optics to shape fs-laser pulses, the two-photon spectrum is discretized into frequency bins.

Towards Integrated Photonics for Quantum Computation

Hugo Cable, University of Bristol, UK

I will give an overview of work at the Centre for Quantum Photonics towards implementation of large-scale linear-optical quantum computing (LOQC) using quantum photonics. Our current research addresses the key obstacles to scalable LOQC, namely overcoming nondeterminism, achieving loss tolerance, and manufacturability.

Zachary Webb of the Department of Physics and Astronomy is defending his thesis:

Zak is supervised by Assistant Professor Andrew Childs.

Extended nonlocal games and monogamy-of-entanglement games

Vincent Russo, Institute for Quantum Computing

Two-player one-round games have served to be an instrumental model in theoretical computer science. Likewise, nonlocal games consider this model when the players have access to an entangled quantum state. In this talk, I will consider a broader class of nonlocal games (extended-nonlocal games), where the referee shares an entangled state along with the players.

Kent Fisher of the Department of Physics and Astronomy is defending his thesis:

Photons & Phonons: A room-temperature diamond quantum memory

Kent is supervised by Professor Kevin Resch.
