Description:
Author(s): Zixin Huang, Chiara Macchiavello, and Lorenzo Maccone For phase estimation using qubits, we show that for some noise channels, the optimal entanglement-assisted strategy depends on the noise level. We note that there is a nontrivial crossover between the parallel-entangled strategy and the ancilla-assisted strategy: in the former the probes are all ent... [Phys. Rev.
