Better Heisenberg Limits, Coherence Bounds, and Energy-Time Tradeoffs via Quantum Rényi Information
An uncertainty relation for the Rényi entropies of conjugate quantum observables is used to obtain a strong Heisenberg limit of the form [Formula: see text] , bounding the root mean square error of any estimate of a random optical phase shift in terms of average photon number, where [Formula: see te...
