• Abstract: We address the exploitation of an optical parametric oscillator (OPO) in the task of mitigating, at least partially, phase noise produced by phase diffusion. In particular, we analyze two scenarios where phase diffusion is typically present. The first one is the measurement of the phase of a noisy optical field, while the second involves a quantum estimation scheme of a phase shift imposed on a noisy probe. In both cases, we prove that an OPO may lead to a partial or full compensation of the noise.

  We experimentally reconstruct different wavefronts by means of a point diffraction interferometer for different mean intensities of illumination. For two cases of interest, a spatial qudit encoding phase, consisting of d = 6 uniform phase regions, and a more general continuous phase, we see that reducing the readout noise leads to a clear improvement in the quality of reconstruction.

  We study how time-dependent energy fluctuations impact the quantum phase transitions following a noisy quench of the transverse magnetic field in a quantum Ising chain. We trace the phenomenon to the interplay between noise-induced excitations which accumulate during the quench and the nearadiabatic dynamics of the system.

  We develop an error mitigation method for the control-free phase estimation. We prove a theorem that under the first-order correction, the noise channels with only Hermitian Kraus operators do not change the phases of a unitary operator. Our method paves the way for the utilization of quantum phase estimation before the advent of fault-tolerant quantum computers.
