Quantum-Optimal Frequency Estimation of Stochastic AC Fields
Anirban Dey, Sara Mouradian, Cosmo Lupo +1
Resolving frequencies in a time-dependent field is classically limited by the measurement bandwidth. Using tools from quantum metrology and quantum control may overcome this limit,…
Optimal and robust error filtration for quantum information processing
Aaqib Ali, Giovanni Scala, Cosmo Lupo
Error filtration is a hardware scheme that mitigates noise by exploiting auxiliary qubits and entangling gates. Although both signal and ancillas are subject to local noise, constr…
Machine learning with sub-diffraction resolution in the photon-counting regime
Giuseppe Buonaiuto, Cosmo Lupo
The resolution of optical imaging is classically limited by the width of the point-spread function, which in turn is determined by the Rayleigh length. Recently, spatial-mode demul…
Security of hybrid BB84 with heterodyne detection
Jasminder S. Sidhu, Rocco Maggi, Saverio Pascazio +1
Quantum key distribution (QKD) promises everlasting security based on the laws of physics. Most common protocols are grouped into two distinct categories based on the degrees of fr…
