The Quantum Innovators in science and engineering workshop brings together the most promising young researchers in quantum physics and engineering. Guests are invited for a four-day conference aimed at exploring the frontier of our field.

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.

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.

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.

In a non-local game, two or more non-communicating, but entangled, players cooperatively try to win a game consisting of a one-round interaction with a classical referee. In this talk, I will describe a two-player non-local game with the property that an epsilon-close to optimal strategy requires the players to share an entangled state of dimension 2^{1/poly(epsilon)}.
