Maxwell's demon at work: protection of quantum information in superconducting circuits

Presented by Michel Devoret, Yale

Can we prolong the coherence of a two-state manifold in a complex quantum system beyond the
coherence time of its longest-lived component? This question is the starting point in the
construction of a scalable quantum computer. It translates into the search for hardware-efficient
processes that operate as some sort of Maxwell's demon, reliably correcting the errors resulting
from the coupling between qubits and their environment. The presentation will review recent
experiments that tested the dynamical protection, by Josephson circuits, of a logical qubit
memory based on superpositions of particular coherent states of a superconducting resonator.
