Amplification, Redundancy, and the Quantum Chernoff Information
Michael Zwolak, C. Jess Riedel, Wojciech H. Zurek
Amplification was regarded, since the early days of quantum theory, as a mysterious ingredient that endows quantum microstates with macroscopic consequences, key to the "collapse o…
The Objective Past of a Quantum Universe: Redundant Records of Consistent Histories
C. Jess Riedel, Wojciech H. Zurek, Michael Zwolak
Motivated by the advances of quantum Darwinism and recognizing the role played by redundancy in identifying the small subset of quantum states with resilience characteristic of obj…
Testing quantum adiabaticity with quench echo
H. T. Quan, W. H. Zurek
Adiabaticity of quantum evolution is important in many settings. One example is the adiabatic quantum computation. Nevertheless, up to now, there is no effective method to test the…
Decoherence and the Loschmidt echo
F. M. Cucchietti, D. A. R. Dalvit, J. P. Paz +1
Environment--induced decoherence causes entropy increase. It can be quantified using, e.g., the purity . When the Hamiltonian of a quantum system is perturbed, its s…
Introduction to Quantum Information Processing
E. Knill, R. Laflamme, H. Barnum +7
As a result of the capabilities of quantum information, the science of quantum information processing is now a prospering, interdisciplinary field focused on better understanding t…
Algorithmic randomness, physical entropy, measurements, and the Demon of Choice
W. H. Zurek
Measurements --- interactions which establish correlations between a system and a recording device --- can be made thermodynamically reversible. One might be concerned that such re…
Threshold Accuracy for Quantum Computation
E. Knill, R. Laflamme, W. Zurek
We have previously (quant-ph/9608012) shown that for quantum memories and quantum communication, a state can be transmitted over arbitrary distances with error provided each ga…
Decoherence of Quantum Fields: Pointer States and Predictability
J. R. Anglin, W. H. Zurek
We study environmentally induced decoherence of an electromagnetic field in a homogeneous, linear, dielectric medium. We derive an independent oscillator model for such an environm…
