Pawel Caputa (Warsaw U.), Quantum Complexity in the Krylov basis.

Tuesday 18 Oct 2022, 14:00 → 15:30 Europe/Stockholm

Albano 3: 6228 - Mega (22 seats) (Albano Building 3)

Abstract: I will review a recent progress on defining a universal 
measure of quantum complexity based on the so-called Krylov basis. In 
particular, after introducing some of the Krylov basis techniques, I 
will discuss the “Spread Complexity” measure for quantum states and its 
main properties. The talk will be based on:
