Quantum decoherence plays a pivotal role in the dynamical description of the quantum-to-
classical transition and is the main impediment to the realization of devices for quantum …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

The topic of quantum noise has become extremely timely due to the rise of quantum
information physics and the resulting interchange of ideas between the condensed matter …

We propose a realizable architecture using one-dimensional transmission line resonators to
reach the strong-coupling limit of cavity quantum electrodynamics in superconducting …

Over the course of the past decade, decoherence has become a ubiquitous scienti? c term
popular in all kinds of research, from fundamental theories of quantum physics to …

Superconducting circuits based on Josephson junctions exhibit macroscopic quantum
coherence and can behave like artificial atoms. Recent technological advances have made …

The violation of Bell inequalities with two entangled and spatially separated quantum two-
level systems (TLSs) is often considered as the most prominent demonstration that nature …

We demonstrate quantum bath engineering for a superconducting artificial atom coupled to
a microwave cavity. By tailoring the spectrum of microwave photon shot noise in the cavity …

Analog processors for Solving various computational prob lems are provided. Such analog
processors comprise a plu rality of quantum devices, arranged in a lattice, together with a …

A flux qubit can have a relatively long decoherence time at the degeneracy point, but away
from this point the decoherence time is greatly reduced by dephasing. This limits the …
