The goal of two-party cryptography is to enable Alice and Bob to solve tasks in cooperation even if they do not trust each other. Examples of such tasks include bit commitment, coin flipping and oblivious transfer. Unfortunately, it has been shown that even using quantum communication, none of these tasks can be implemented when the adversary is completely general.

We discuss a device capable of filtering out two-mode states of light with mode populations differing by more than a certain threshold, while not revealing which mode is more populated. It would allow engineering of macroscopic quantum states of light in a way which is preserving specific superpositions. As a result, it would enhance optical phase estimation with these states. We propose an optical scheme, which is a relatively simple, albeit non-ideal, operational implementation of such a filter.

IQC presents the first in a series of lectures from members of industry in quantum computing and quantum information. Jonathan Hodges, VP of engineering for Diamond Nanotechnologies, will be speaking about his research as well as the day-to-day realities of working in industry.

Progress in the field of experimental quantum information processing has been steady over the past decade with important developments continuing to be made in the understanding, design, and measurement of systems at the quantum level. As the boundaries of these measurements are pushed, we are finding that surface and interfacial properties play an increasingly important role. In general, this field has benefitted immensely from advances in VLSI.

In this talk, I will give a summary of my recent research on superconducting nanostructures for quantum detection of electromagnetic radiation. In this regard, electrodynamics of topological excitations in 1D superconducting nanowires and 2D superconducting nanostrips is investigated. Topological excitations in superconducting nanowires and nanostrips lead to crucial deviation from the bulk properties.

We will review several proof of principle applications for graphene based devices performed in our group, including in field sensors, electronics, THz spectroscopy, spintronics, nanofluidics, and even musical instruments. We will then discuss the synthesis mechanism of graphene as well as the synthesis of very large single layered graphene monocrystals with various shapes, ranging from hexagons to fractals, dubbed graphlocons.
