In situ characterization of a photon-subtraction device via heralding counts and homodyne detection
Priyanka Sharma, Matteo G. A. Paris, Stefano Olivares
Photon subtraction is one of the most important techniques for generating non-Gaussian optical states and constitutes a key resource for quantum information processing and quantum…
Quadratic and cubic scrambling in the estimation of two successive phase-shifts
Manju, Stefano Olivares, Matteo G. A. Paris
Multiparameter quantum estimation becomes challenging when the parameters are incompatible, i.e., when their respective symmetric logarithmic derivatives do not commute, or when th…
Generation and detection of squeezed states via a synchronously pumped optical parametric oscillator
Edoardo Suerra, Samuele Altilia, Stefano Olivares +7
A synchronously pumped optical parametric oscillator (SPOPO) operating at 93 MHz is used to generate squeezed states at 1035 nm. The system features a counter-propagating beam at t…
A minimalist self-differencing gating scheme for dead-time-free single-photon avalanche diodes at high repetition rate
Samuele Altilia, Edoardo Suerra, Stefano Capra +6
Gated quenched SPAD detectors are widely used in quantum communication and quantum computing setups employing high-repetition-rate lasers. Here, we present a novel scheme for high-…
Mitigating sloppiness in joint estimation of successive squeezing parameters
Priyanka Sharma, Stefano Olivares, Devendra Kumar Mishra +1
When two successive squeezing operations with the same phase are applied to a field mode, reliably estimating the amplitude of each is impossible because the output state depends s…
The ultimate bounds to precision of atomic clock frequency measurement techniques
Stefano Olivares, Salvatore Micalizio, Matteo G. A. Paris
We investigate the ultimate quantum limits to the achievable uncertainty in the estimation of the transition frequency between two atomic levels. We focus on Rabi, Ramsey, and cohe…
Local discrimination of orbital angular momentum in entangled states
Simone Cialdi, Edoardo Suerra, Samuele Altilia +5
We address the use of a calcite crystal-based local detector to the discrimination of orbital angular momentum of quantum radiation produced by parametric down conversion. We demon…
High-order dispersion effects in two-photon interference
Z. Mazzotta, S. Cialdi, D. Cipriani +2
Two-photon interference and Hong-Ou-Mandel (HOM) effect are relevant tools for quantum metrology and quantum information processing. In optical coherence tomography, HOM effect is…
