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
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,
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
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,
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
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
Wednesday, 16 March 2022 @ 12PM in 149 Keck Center, or join us on Zoom. Abstract: In this talk, we are interested in techniques to recover the moment of magnetization given measurements of the magnetic field. We introduce the notion of inverse problems and we write the question of moment recovery as an inverse problem.
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
Wednesday, 9 March 2022 @ 12PM in 149 Keck Center, or join us on Zoom. Abstract: Spontaneous collapse models models and Bohmian mechanics are two different solutions to the measurement problem plaguing orthodox quantum mechanics. They have a priori nothing in common. At a formal level, collapse models add a non-linear noise term to the
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?
