“Quantum physics” has taken its position with “rocket science” in pop culture as a shorthand for frighteningly complicated science. Quantum physics has also taken on a sort of magical connotation in fiction, with features like entanglement, superposition, and tunneling, spurring imagination. But where does the science draw the line? How much is joyful speculation, and how much is disregard for reality? And if it’s always seen as either magical or scary, how does that affect the perception of quantum science?

Speaker: Thomas K. Hunter and Neil Henderson

Abstract:

A lot of different concepts and possibilities have been discussed. The final session will recap those and put them in perspective, with emphasis on the relevance to a "typical" university start up and the people involved.

This is the final lecture in the CryptoWorks21 Intellectual Property (IP) Management Lunch and Learn Lecture Series. Knowledgeable speakers will give in-depth presentations that build on previous sessions.

What makes someone a good ally? How can you use your privilege to stand up and support others?

This presentation will delve into a practical example of a patent procedure associated to a specific quantum technology: quantum random number generator. We will explore the specifics of the technology and its applications, review previously existing approaches and define the inventive step, explore the phrasing of the claims, and revisit the prior patents from the freedom-to-operate point of view.

Quantum coherence control in an inhomogeneously broadened lambda-type solid state ensemble has been studied for quantum memories over decades. Unlike akali atoms, the optically excited spin coherence in a rare-earth doped solid is sufferred from a serious spin dephasing problem due to spin inhomogeneity. Thus, solid state quantum memory protocols such as AFC and gradient echo have been effctively demonstrated only for optical transitions, whose coherence time is far shorter than ms.

The event will feature a panel of four speakers who will share how their agency or organization supports start-ups and commercialization of IP, including funding sources and services available to faculty and start-ups. Each panelist will provide a brief presentation and respond to a set of questions followed by a Q&A session. Informal networking will take place between 1:00pm and 1:30pm.

IQC Colloquium

Stephen Bartlett, The University of Sydney

Quantum information is very fragile, but clever quantum engineers aspire to use error correction to keep information intact. Topologically ordered phases—wherein the most exotic properties of quantum physics such as entanglement are protected within a strongly-interacting material—are currently being commandeered as quantum error-correcting codes for today’s quantum architectures. I’ll introduce these as well as a new generation of theoretical materials that promise to self-correct themselves.

Andrea Coladangelo, Caltech

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)}.

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.
