A simple example of "Quantum Darwinism": Redundant information storage in many-spin environments
Robin Blume-Kohout, Wojciech H. Zurek
As quantum information science approaches the goal of constructing quantum computers, understanding loss of information through decoherence becomes increasingly important. The info…
Quantum Darwinism and Envariance
W. H. Zurek
Effective classicality of a property of a quantum system can be defined using redundancy of its record in the environment. This allows quantum physics to approximate the situation…
Decoherence and the transition from quantum to classical -- REVISITED
Wojciech H. Zurek
The environment surrounding a quantum system can, in effect, monitor some of the systems observables. As a result, the eigenstates of these observables continuously decohere and ca…
Reduction of the Wavepacket: How Long Does it Take?
Wojciech H. Zurek
We show that the ``reduction of the wavepacket'' caused by the interaction with the environment occurs on a timescale which is typically many orders of magnitude shorter than the r…
Maxwell's Demon, Szilard's Engine and Quantum Measurements
Wojciech Hubert Zurek
We propose and analyze a quantum version of Szilard's ``one-molecule engine.'' In particular, we recover, in the quantum context, Szilard's conclusion concerning the free energy ``…
Introduction to Quantum Error Correction
E. Knill, R. Laflamme, A. Ashikhmin +3
In this introduction we motivate and explain the ``decoding'' and ``subsystems'' view of quantum error correction. We explain how quantum noise in QIP can be described and classifi…
