Quantum metrology uses quantum states with no classical counterpart to measure a physical quantity with extraordinary sensitivity or precision. Most such schemes characterize a dynamical process by probing it with a specially designed quantum state.

We theoretically investigate the effects of parasitic quantum nonlinear optical processes on the generation of squeezed light in a dual-pumped integrated microring resonator coupled to a waveguide.

We report demonstrations of both quadrature squeezed vacuum and photon number difference squeezing generated in an integrated nanophotonic device. Squeezed light is generated via strongly driven spontaneous four-wave mixing below threshold in silicon

We perform on-chip heterodyne tomography of the quantum state generated by a heralded microring single photon source. The quantum state is generated and characterized without ever being coupled off-chip.

We use hollow-core fibre to preserve the spectrum and temporal profile of picosecond laser pulses in CBD to suppress 2.6 dB of amplitude noise at MHz noise frequencies, to within 0.01 dB of the shot-noise limit. We provide an enhanced version of the

Random numbers are a fundamental resource in science and technology. Among the different approaches to generating them, random numbers created by exploiting the laws of quantum mechanics have proven to be reliable and can be produced at enough rates

It was recently shown that it is possible to construct an error–disturbance relation having the same form as Heisenberg’s original heuristic definition (Busch et al., Phys Rev Lett 111:160405, 2013), in contrast to the formula proposed by Ozawa w
