Quantum Steampunk: The Physics of Yesterday's Tomorrow

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

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,


Detecting Axions from electron-spin precession

April 12, 2022 by | Uncategorized

Thursday, 14 April 2022 @ 4 PM in 149 Keck Center, or join us on Zoom. Abstract:  After a pedagogical introduction of Axion and the Strong CP problem, I will show how the axion induces an additional spin-precession in the Schrodinger equation.  We will together explore the possibility of using ideas in weak measurements to


The arrow of time in a relational universe

April 5, 2022 by | Uncategorized

Wednesday, 13 April 2022 @ 12PM in 149 Keck Center, or join us on Zoom. Abstract: Relationalism posits that one must be able to describe the universe as a whole without reference to any external structure (clocks, rods, frame of reference, etc.) and should consequently also not obey any external arrow of time. Clocks, rods,


No-signalling assamblages beyond quantum mechanics: when quantum theory can generate extremal points in a post-quantum framework

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


Welcome John Howell!

March 9, 2022 by | Uncategorized

Dear IQS members, We are delighted to announce that John Howell will be joining us here as a new faculty member at Chapman University in the coming summer.  John is an expert in quantum optics, quantum information, precision measurements, and all manner of optical imaging. An overview of his work is on his Google scholar


"Implications of action principles for quantum foundations"

February 28, 2022 by | Uncategorized

Thursday, March 3rd, 2022, 11 AM, Keck Center 149 Join us on Zoom. Abstract: The classical action has been intertwined with quantum theory for over a century, but the connection between the two continues to be unclear.  Is the action meaningful in its own right, or just a “trick” for generating dynamical equations of motion?
