What we need for useful quantum computers and how to get there: error mitigation
William Zeng, Unitary Fund
Event Type: CQIP Seminar
Time: 11:00 AM - 12:00 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: Quantum computers have theoretical promise as useful industrial and scientific tools. This talk will be in two parts. In the first, we will use finance applications of simulation and optimization as a case study to estimate the performance of a quantum computers that would be needed for useful advantage. This work indicates that significant reductions in error rates are needed. In the second part of the talk, we will review new error mitigating techniques for compiling quantum programs to be robust against errors. We review the role these error mitigating techniques could play with quantum error correction to make needed error reductions.

Present and Future of the Conformal Bootstrap
Shai Chester, Harvard University
Event Type: Special Seminar
Time: 12:50 PM - 3:00 PM
Location: 726 Broadway, 940, CCPP Seminar
Abstract: I will start by reviewing the most notable results of the numerical conformal bootstrap, as applied to conformal field theories (CFTs) in condensed matter, particle physics, and quantum gravity. This includes the most precise determination of critical exponents for the superfluid Helium transition, as well as the first non-perturbative calculation of the low-lying spectrum of a non-abelian gauge theory, which also has a holographic interpretation. I will then present outstanding problems, both general principles and specific physical systems, that the bootstrap would like to tackle in the next few years.
