Universal quantum data compression via gentle tomography
arXiv:quant-ph/0403078 · doi:10.1103/PhysRevA.73.032336
Abstract
Quantum state tomography--the practice of estimating a quantum state by performing measurements on it--is useful in a variety of contexts. We introduce "gentle tomography" as a version of tomography that preserves the measured quantum data. As an application of gentle tomography, we describe a simple polynomial-time method for universal source coding.
