    "abstract": "We formulate quantum rate-distortion theory in the most general setting where\nclassical side information is included in the tradeoff. Using a natural\ndistortion measure based on entanglement fidelity and specializing to the case\nof an unrestricted classical side channel, we find the exact quantum\nrate-distortion function for a source of isotropic qubits. An upper bound we\nbelieve to be exact is found in the case of biased sources. We establish that\nin this scenario optimal rate-distortion codes produce no entropy exchange with\nthe environment of any individual qubit.",
