Quantum metrology employs quantum resources to enhance the measurement sensitivity
beyond that can be achieved classically. While multiphoton entangled N00N states can in …

The modern scientific method is critically dependent on precision measurements of physical
parameters. A classic example is the measurement of the optical phase enabled by optical …

Recently, integrated photonic circuits have brought new capabilities to electron microscopy
and been used to demonstrate efficient electron phase modulation and electron-photon …

Photons are the physical system of choice for performing experimental tests of the
foundations of quantum mechanics. Furthermore, photonic quantum technology is a main …

Optical interferometers are pillars of modern precision metrology, but their resolution is
limited by the wavelength of the light source, which cannot be infinitely reduced. Magically …

To eliminate the problem that external stray light affects the detection result, a microfiber
quantum sensor for high-precision protein measurement with two photon N00N state is …

All roads lead to Rome. In this article we propose a novel theoretical framework to
demonstrate vector beams whose degree of polarization does not change on atmospheric …

We propose a protocol to overcome the shot noise limit and reach the Heisenberg scaling
limit for parameter estimation by using quantum optimal control and a time-reversal strategy …

We demonstrate the generation of unbalanced two-photon entanglement in the Laguerre–
Gaussian (LG) transverse-spatial degree-of-freedom, where one photon carries a …

We propose a protocol for the generation of NOON states of resonator modes. The physical
model is composed of two Kerr-nonlinear resonators and a four-level qudit. Using the off …
