Bounding quantum advantages in Postselected Metrology A Technical Physics Talk by Subhrajit Modak

April 28, 2022 by | Uncategorized

Friday, 6 May 2022 @ 9 AM. Join us on Zoom. Abstract: Weak value amplification and other postselection-based metrological protocols can enhance precision while estimating small parameters, outperforming postselection-free protocols. In general, these enhancements are largely constrained because the protocols yielding higher precision are rarely obtained due to a lower probability of successful postselection. It

Quantum Steampunk: The Physics of Yesterday’s Tomorrow A Popular Physics Talk by Nicole Yunger Halpern

April 22, 2022 by | Uncategorized

Wednesday, 27 April in 404 Beckman Hall at 6PM, or join us on Zoom. The Industrial Revolution meets the quantum-technology revolution! A steampunk adventure guide to how mind-blowing quantum physics is transforming our understanding of information and energy. Victorian era steam engines and particle physics may seem worlds (as well as centuries) apart, yet a

Weak measurements and quantum Zeno effect A Technical Physics Talk by Stanislaw Soltan

April 18, 2022 by | Uncategorized

Friday, 22 April 2022 @ 9 AM. Join us on Zoom. Abstract: A quantum decaying system can reveal its nonclassical behavior by being noninvasively measured. Correlations of weak measurements in the noninvasive limit violate the classical bound for a universal class of systems. The violation is related to incompatibility between exponential decay and unitary evolution,

No-signalling assamblages beyond quantum mechanics: when quantum theory can generate extremal points in a post-quantum framework A Technical Physics Talk by Paweł Horodecki

April 4, 2022 by | Uncategorized

Wednesday, 6 April 2022 @ 12PM in 149 Keck Center, or join us on Zoom. Abstract: It is well known that in the language of  no-signaling boxes  – consistent families of probabilites representing measurement correlations –  the following three sets: local deterministic, quantum and no-signalling constitute the increasing sequence with strict inclusions. Moreover the outer

Exploring Quantum Mysteries Drives Chapman Institute Toward Breakthroughs Building on foundational research, co-director Andrew Jordan seeks to expand the scope of the Institute for Quantum Studies.

March 25, 2022 by | Uncategorized

Ever since high school, Andrew Jordan has been fascinated by the promise and possibilities of quantum mechanics. So much so that he has devoted his professional life to the study of matter and light on the atomic and subatomic scale. Decades later, the field still amazes him. “Part of the excitement is that things in
