Seminar Abstract:

Abstract: Rydberg atom arrays have emerged as a promising candidate for quantum computation. However, scaling up the platform beyond a few thousand qubits would require a modular approach. An integrated optical cavity could serve as a quantum networking node between distant quantum processors. In this talk, I will show our results towards this integration for two candidate platforms: a nano-photonic crystal cavity (PCC) and a Fabry-Perot Fiber cavity (FPFC).

Join us for the talk in the auditorium at 2:00 p.m., and a reception with cake in the h-Bar following the talk!

Abstract: Reconfigurable arrays of neutral atoms combined with coherent Rydberg interactions are an exciting platform to study quantum many-body phenomena and quantum information protocols.

Abstract: On January 15, 2022, the eruption of a submarine volcano in Hunga Tonga – Hunga Ha`apai (HTHH, 20.54°S, 175.38°W) resulted in a volcanic plume that reached a height of 57 km, increasing the total stratospheric water vapor burden by 10% and forming a sulfate aerosol layer. Satellite observations in the summer of 2022 revealed the lowest tropical mesospheric temperatures and highest extratropical mesospheric temperatures observed in the past 20 years.

Abstract: We propose an application for near-term quantum devices:

namely, generating cryptographically certified random bits, to use

(for example) in proof-of-stake cryptocurrencies. Our protocol

repurposes the existing "quantum supremacy" experiments, based on

random circuit sampling, that Google and USTC have successfully

carried out starting in 2019. We show that, whenever the outputs of

The CUbit Quantum Initiative presents our next speaker of the Spring 2023 CUbit Quantum Seminar Series, Professor Mikhail Lukin (Harvard).  Professor Lukin will speak on Monday, May 1st at 4:00 pm in the CASE Auditorium. Coffee and cookies will be offered beginning at 3:30 pm.

Lunch will be provided at 12:00pm, so please come early to eat mingle and eat lunch before the talk begins.

Abstract: I’ll show that there exists a fundamental upper limit on the electron-phonon coupling strength in metals. This, in turn, implies an upper bound on the superconducting Tc. I’ll compare these bounds with new and old experimental data and ague that our theory explains several previously poorly understood experiments, such as the observation of metastable high-temperature superconductivity in FeSe.

Synopsis: The Huttenlocher lab’s research is aimed at understanding the cellular and molecular mechanisms that regulate cell migration and wound healing using biochemical genetic and imaging approaches. They use live imaging, biosensors and photomanipulation to examine and control polarity of cell signaling during cell migration in live animals and understand how these mechanisms are altered in tissue damage and repair.
