Advances in quantum metrology [PDF]

Nature Photonics, 2011
In classical estimation theory, the central limit theorem implies that the statistical error in a measurement outcome can be reduced by an amount proportional to n^(-1/2) by repeating the measures n times and then averaging. Using quantum effects, such as entanglement, it is often possible to do better, decreasing the error by an amount proportional to

Memory Effects in Quantum Metrology [PDF]

Physical Review Letters, 2019
Quantum metrology concerns estimating a parameter from multiple identical uses of a quantum channel. We extend quantum metrology beyond this standard setting and consider estimation of a physical process with quantum memory, here referred to as a parametrized quantum comb.

Metrology for Quantum Communication

2015 IEEE Globecom Workshops (GC Wkshps), 2015
INRIM is making efforts to produce a metrology for quantum communication purposes, ranging from the establishment of measurement procedures for specific quantities related to QKD components, namely pseudo single-photon sources and detectors, to the implementation of novel QKD protocol based on paradigm other than non-commuting observables, to the ...

Multi-parameter quantum metrology [PDF]

Advances in Physics: X, 2016
The simultaneous quantum estimation of multiple parameters can provide a better precision than estimating them individually. This is an effect that is impossible classically. We review the rich background of multi-parameter quantum metrology, some of the main results in the field and its recent advances.
