Theory of Quantum Comb Enhanced Interferometry

Author(s): Haowei Shi and Quntao Zhuang Optical frequency combs, named for their comblike peaks in the spectrum, are essential for various sensing applications. As the technology develops, its performance has reached the standard quantum limit dictated by the quantum fluctuations of coherent light field. Quantum combs, with their quantum … [Phys. Rev.
