It is well known in Bayesian estimation theory that the conditional estimator attains the
minimum mean squared error (MMSE) for estimating a scalar parameter of interest. In …

Quantum theory allows the traversing of multiple channels in a superposition of different
orders. When the order in which the channels are traversed is controlled by an auxiliary …

This work compares the performance of single-and two-qubit probes for estimating several
phase rotations simultaneously under the action of different noisy channels. We compute the …

Polarization is one of light's most versatile degrees of freedom for both classical and
quantum applications. The ability to measure light's state of polarization and changes …

The concentration of a chiral solution is a key parameter in many scientific fields and
industrial processes. This parameter can be estimated to high precision by exploiting …

One of the goals of a traditional imaging system is to acquire image of the scene with the
highest-resolution possible to infer relevant details or features. However, the traditional …

Precision measurements and sensing are crucial in every scientific and technological field.
Quantum metrology, a branch of quantum information science, aims to maximize precision in …

The Kramers-Kronig (KK) receiver provides an efficient method to reconstruct the complex-
valued optical field by means of intensity detection given a minimum-phase signal. In this …
