Phase Stabilization of a Frequency Comb using Multipulse Quantum Interferometry Cadarso, Andrea Mur Petit, Jordi García Ripoll, Juan José From the interaction between a frequency comb and an atomic qubit, we derive quantum protocols for the determination of the carrier-envelope offset phase, using the qubit coherence as a reference, and without the need of frequency doubling or an octave spanning comb. Compared with a trivial interference protocol, the multipulse protocol results in a polynomial enhancement of the sensitivity O(N−2) with the number N of laser pulses involved. We specialize the protocols using optical or hyperfine qubits, Λ schemes, and Raman transitions, and introduce methods where the reference is another phase-stable cw laser or frequency comb. 2023-06-19T13:27:14Z 2023-06-19T13:27:14Z 2014-02-21 journal article 0031-9007 10.1103/PhysRevLett.112.073603 https://hdl.handle.net/20.500.14352/33744 http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.112.073603#abstract eng QUITEMAD-CM (S2009/ESP-1594) (FIS2012-33022) JAE-Doc program (MP1001) open access American Physical Society
