[Aspuru-Guzik Group List] [qip] Fwd: REMINDER: Mathematical Picture Language Seminar at Harvard on Tuesday, January 28

by Aram Harrow

Dear quanta, I am speaking tomorrow at Harvard on my recent paper with John, Rolando + Caltech people on simulating 2D random circuits. Below is the announcement. -aram ---- Hi All, Here is the notice for the Mathematical Picture Language Seminar on Tuesday, January 28 at 3:30 p.m. I attach the flyer, and include the details below in case you don’t want to access the attachment: 3:30 PM Tuesday, January 28, 2020 Harvard University Mathematical Picture Language Seminar Jefferson 356 “Phase transitions in the complexity of simulating random shallow quantum circuits” Aram Harrow, MIT *Abstract:* The appeal of quantum computing is based on the fact that simulating N quantum systems on a classical computer takes time exponential in N. This exponential hardness is known to hold even for shallow quantum circuits, meaning unitary dynamics that run for a constant amount of time. We show that when the quantum circuits are made of random gates on a 2D geometry, they are not always exponentially hard to simulate. Instead, we give evidence for a phase transition in computational difficulty as the depth and local dimension are varied. Our evidence consists of (1) fast classical simulations of random circuits on a 400x400 grid of qubits, (2) a mapping to the order/disorder transition in an associated stat mech model, and (3) a proof that some circuit families are easy to simulate approximately but hard to simulate exactly. Our algorithms are based on tensor network contraction and mapping the 2D random unitary circuit to a 1D process consisting of alternating rounds of random local unitaries and weak measurements. This is based on https://arxiv.org/abs/2001.00021 <https://urldefense.proofpoint.com/v2/url?u=https-3A__arxiv.org_abs_2001.000…> which is joint work with John Napp, Rolando La Placa, Alexander Dalzell, and Fernando Brandao.

[Aspuru-Guzik Group List] [qip] group meeting today

by Aram Harrow

Dear quanta, A reminder that we will meet at 11 today in the usual place. After we have been hearing so much about the undecidability of entangled games, Adam will tell us some positive news about algorithms. aram _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip
