Quantum Illumination with a generic Gaussian source
Athena Karsa, Gaetana Spedalieri, Quntao Zhuang +1
With the aim to loosen the entanglement requirements of quantum illumination, we study the performance of a family of Gaussian states at the transmitter, combined with an optimal a…
Detecting and tracking bacteria with quantum light
Gaetana Spedalieri, Lolita Piersimoni, Omar Laurino +2
The field of quantum sensing aims at improving the detection and estimation of classical parameters that are encoded in physical systems by resorting to quantum sources of light an…
Discrimination of discord in separable Gaussian states
Gaetana Spedalieri, Stefano Pirandola, Samuel L. Braunstein
Consider two bosonic modes which are prepared in one of two possible Gaussian states with the same local energy: either a tensor-product thermal state (with zero correlations) or a…
Symmetric and asymmetric discrimination of bosonic loss: Toy applications to biological samples and photo-degradable materials
Gaetana Spedalieri, Stefano Pirandola, Samuel L. Braunstein
We consider quantum discrimination of bosonic loss based on both symmetric and asymmetric hypothesis testing. In both approaches, an entangled resource is able to outperform any cl…
Continuous-variable quantum cryptography with an untrusted relay: Detailed security analysis of the symmetric configuration
Carlo Ottaviani, Gaetana Spedalieri, Samuel L. Braunstein +1
We consider the continuous-variable protocol of Pirandola et al. [Nature Photonics 9, 397-402 (2015), see also arXiv.1312.4104] where the secret-key is established by the measureme…
Non-Markovian Reactivation of Quantum Relays
Stefano Pirandola, Carlo Ottaviani, Christian S. Jacobsen +4
We consider a quantum relay which is used by two parties to perform several continuous-variable protocols: Entanglement swapping, distillation, quantum teleportation, and quantum k…
