Optimal phase estimation for qubits states
Presenting Author: Marco Antonio Rodríguez García, Universidad Nacional Autonoma de Mexico
Contributing Author(s): Pablo Barberis Blostein
In this work, we will develop optimal strategies for phase estimation in pure qubits states, for multiple copies of qubits prepared in the same state. We find different types of optimal setups in three regimes, for one observation, multiple finite observations and the asymptotic regime. In the asymptotic regime, the setup saturates the Crámer-Rao bound.
