Quantum Bell-Ziv-Zakai Bounds and Heisenberg Limits for Waveform Estimation
We propose quantum versions of the Bell-Ziv-Zakai lower bounds for the error in multiparameter estimation. As an application, we consider measurement of a time-varying optical phase signal with stationary Gaussian prior statistics and a power-law spectrum ∼1/|ω|^{p}, with p>1. With no other assum...
