Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

VIRTUAL INPA SEMINAR – Chia-Cheng Chang (LBNL)

May 15, 2020 @ 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..
