Quantum Rate-Distortion Theory for I.I.D. Sources
We consider a natural distortion measure based on entanglement fidelity and find the exact rate-distortion function for isotropic sources. An upper bound is found in the case of biased sources which we believe to be exact. We conclude that optimal rate-distortion codes for this measure produce no entropy exchange with the environment of any individual qubit.
متن کاملQuantum rate-distortion theory for memoryless sources
We formulate quantum rate-distortion theory in the most general setting where classical side information is included in the tradeoff. Using a natural distortion measure based on entanglement fidelity and specializing to the case of an unrestricted classical side channel, we find the exact quantum rate-distortion function for a source of isotropic qubits. An upper bound we believe to be exact is...
متن کاملTrue precision limits in quantum metrology
Quantum mechanics provides insight into fundamental limits on the achievable measurement precision that cannot be beaten irrespectively of the extent of any improvements in measurement technology. The best known example is that of the optical phase measurement where difference of phase delays φ in the arms of interferometer in the absence of decoherence can only be measured up to a precision kn...
متن کاملFundamental Limits of Video Coding: A Closed-form Characterization of Rate Distortion Region from First Principles
Classical motion-compensated video coding methods have been standardized by MPEG over the years and video codecs have become integral parts of media entertainment applications. Despite the ubiquitous use of video coding techniques, it is interesting to note that a closed form rate-distortion characterization for video coding is not available in the literature. In this paper, we develop a simple...
متن کاملQuantum metrology from an information theory perspective
Questions about quantum limits on measurement precision were once viewed from the perspective of how to reduce or avoid the effects of quantum noise. With the advent of quantum information science came a paradigm shift to proving rigorous bounds on measurement precision. These bounds have been interpreted as saying, first, that the best achievable sensitivity scales as 1/n, where n is the numbe...
