Monitoring dispersive samples with single photons: the role of frequency correlations
Emanuele Roccia, Marco G. Genoni, Luca Mancino +3
The physics that governs quantum monitoring may involve other degrees of freedom than the ones initialised and controlled for probing. In this context we address the simultaneous e…
Heralded generation of high-purity ultrashort single photons in programmable temporal shapes
Vahid Ansari, Emanuele Roccia, Matteo Santandrea +9
We experimentally demonstrate a source of nearly pure single photons in arbitrary temporal shapes heralded from a parametric down-conversion (PDC) source at telecom wavelengths. Th…
Experimental ancilla-assisted phase-estimation in a noisy channel
Marco Sbroscia, Ilaria Gianani, Luca Mancino +5
The metrological ability of carefully designed probes can be spoilt by the presence of noisy processes occurring during their evolution. The noise is responsible for altering the e…
Amending entanglement-breaking channels via intermediate unitary operations
Álvaro Cuevas, Antonella De Pasquale, Andrea Mari +9
We report a bulk optics experiment demonstrating the possibility of restoring the entanglement distribution through noisy quantum channels by inserting a suitable unitary operation…
Entangling measurements for multiparameter estimation with two qubits
Emanuele Roccia, Ilaria Gianani, Luca Mancino +4
Careful tailoring the quantum state of probes offers the capability of investigating matter at unprecedented precisions. Rarely, however, the interaction with the sample is fully e…
Information-thermodynamics of Quantum Generalized Measurements
Luca Mancino, Marco Sbroscia, Emanuele Roccia +5
Landauer's principle introduces a symmetry between computational and physical processes: erasure of information, a logically irreversible operation, must be underlain by an irrever…
