About the INPA Seminars

All seminars are on Fridays (unless otherwise noted) and start at 12:00 (noon) with a brief presentation of the weekly scientific news. Typically the talks end by 13:00. The seminars take place in Bldg. 50A, room 5132.

The committee members are:

The following Seminar schedule for the Institute for Nuclear and Particle Astrophysics is tentative. The seminar becomes final usually a few days before the Friday of the talk.

VIRTUAL INPA SEMINAR – Chia-Cheng Chang (LBNL)

May 15 @ 12:00 pm - 1:00 pm

Speaker: Chia-Cheng Chang (LBNL)

 Title: Time evolution of open quantum many-body systems

Abstract:

The increasing interest and efforts put forth towards the development of quantum computing have lead to a shift in how one goes about tackling problems that are typically thought of as difficult. In this talk I will discuss a specific paradigm of quantum computing called adiabatic quantum computing, and narrow the scope to discuss what is known as quantum annealing. In particular, the first part of the talk will be devoted to discussing what quantum annealing is, and its connection with adiabatic quantum computing. I will follow by discussing the scope of problems that quantum annealers can hope to solve, include an example for tackling integer linear programming. I will end by discussing our simulation of an open quantum many-body system and compare against experimental results obtained from a DWave quantum annealer. On the DWave, we employ a modified time evolution schedule and observe an improvement in performance. Results from the simulation provide a possible explanation of the underlying physics by correlating algorithmic improvements to the interplay between quantum decoherence and many-body localization..

INPA guests from campus can now come up to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 am to 12:00 noon, and from 1 pm to 5 pm. Note that the seminars are now held in 50A-5132 to accommodate a larger number of attendees.

Also, on Fridays from 1:00 pm to 2:00 pm you are welcome to join the INPA Speaker for a brown-bag lunch in the small Pers Hall conference room, 54-130B.

INPA Tea Series

The Physics and Nuclear Science Divisions have together been leaders in revolutionary changes in our understanding of neutrinos and cosmology. Everyone is welcome to attend the open forum. Tea and light refreshments will be served.
