Unexpected detection rate dependence of the intrinsic detection efficiency in single-photon detectors based on avalanche diodes
Sebastian M. F. Raupach, Ivo Pietro Degiovanni, Hristina Georgieva +6
Single-photon detectors are a pivotal component in photonic quantum technologies. A precise and comprehensive calibration of the intrinsic detection efficiency is of utmost importa…
Spectral emission dependence of tin-vacancy centers in diamond from thermal processing and chemical functionalization
Emilio Corte, Selene Sachero, Sviatoslav Ditalia Tchernij +9
We report a systematic photoluminescence (PL) investigation of the spectral emission properties of individual optical defects fabricated in diamond upon ion implantation and anneal…
Spectral features of Pb-related color centers in diamond
Sviatoslav Ditalia Tchernij, Emilio Corte, Tobias Lühmann +9
We report on the systematic characterization of the optical properties of diamond color centers based on Pb impurities. An ensemble photoluminescence analysis of their spectral emi…
Detection of ultra-weak laser pulses by free-running single-photon detectors: modeling dead time and dark counts effects
Hristina Georgieva, Alice Meda, Sebastian M. F. Raupach +6
In quantum communication systems, the precise estimation of the detector's response to the incoming light is necessary to avoid security breaches. The typical working regime uses a…
Protective Measurement -- a new quantum measurement paradigm: detailed description of the first realisation
Enrico Rebufello, Fabrizio Piacentini, Alessio Avella +9
We present a detailed description of the experiment realising for the first time a protective measurement, a novel measurement protocol which combines weak interactions with a ``pr…
Anomalous weak values via a single photon detection
E. Rebufello, F. Piacentini, A. Avella +7
Is it possible that a measurement of a spin component of a spin-1/2 particle yields the value 100? In 1988 Aharonov, Albert and Vaidman argued that upon pre- and postselection of p…
Quantum Zeno and Anti-Zeno probes of noise correlations in photon polarisation
Salvatore Virzi', Alessio Avella, Fabrizio Piacentini +8
We experimentally demonstrate, for the first time, noise diagnostics by repeated quantum measurements. Specifically, we establish the ability of a single photon, subjected to rando…
Temporal teleportation with pseudo-density operators: how dynamics emerges from temporal entanglement
Chiara Marletto, Vlatko Vedral, Salvatore Virzì +5
We show that, by utilising temporal quantum correlations as expressed by pseudo-density operators (PDOs), it is possible to recover formally the standard quantum dynamical evolutio…
