We review the main works in the field of nonlinear interferometers, which has been
develo** ever since the start of nonlinear optics and has seen growing interest in recent …

Entanglement-enhanced quantum metrology explores the utilization of quantum
entanglement to enhance measurement precision. When particles in a probe are prepared …

ABSTRACT A new type of quantum interferometer was recently realized that employs
parametric amplifiers (PAs) as the wave splitting and mixing elements. The quantum …

An SU (1, 1) interferometer, which replaces the beam splitters in a Mach–Zehnder
interferometer with nonlinear interactions, offers the potential of achieving improved phase …

We theoretically study the phase sensitivity of an SU (1, 1) interferometer with a coherent
state in one input port and a squeezed-vacuum state in the other input port using the method …

We theoretically study the phase sensitivity of an SU (1, 1) interferometer, in which the phase
shift is induced by a Kerr medium, together with a coherent state input and homodyne …

Interferometers are widely used as sensors in precision measurement. Compared with a
conventional Mach–Zehnder interferometer, the sensitivity of a correlation-enhanced …

This book on quantum optics is from the point of view of an experimentalist. It approaches
the theory of quantum optics with the language of optical modes of classical wave theory …

We report on a high-level squeezed vacuum state with maximum quantum noise reduction
of 13.2 dB directly detected at the pump power of 180 mW. The pump power dependence of …

We propose a theoretical scheme of an enhanced phase sensitivity by introducing a
nonlinear phase shifter to the nonconventional interferometer consisting of a balanced beam …
