Lower Bounding the Secret Key Capacity of Bosonic Gaussian Channels via Optimal Gaussian Measurements
Giuseppe Ortolano, Stefano Pirandola, Leonardo Banchi
We find the maximum rate achievable in the private communication over a bosonic quantum channel with a fully Gaussian protocol based on optimal single-mode Gaussian measurements. T…
High resolution quantum enhanced phase imaging of cells
Alberto Paniate, Giuseppe Ortolano, Sarika Soman +2
Recovering both amplitude and phase information from a system is a fundamental goal of optical imaging. At the same time, it is crucial to operate at low photon doses to avoid alte…
Chernoff Information Bottleneck for Covert Quantum Target Sensing
Giuseppe Ortolano, Ivano Ruo-Berchera, Leonardo Banchi
The paradigm of quantum metrology and sensing aims to identify a quantum advantage in precision at a fixed energy of the probe state. However, in practice, employing high-energy cl…
Quantum Target Ranging for LiDAR
Giuseppe Ortolano, Ivano Ruo-Berchera
We investigate Quantum Target Ranging in the context of multi-hypothesis testing and its applicability to real-world LiDAR systems. First, we demonstrate that ranging is generally…
Quantum enhanced non-interferometric quantitative phase imaging
Giuseppe Ortolano, Alberto Paniate, Pauline Boucher +5
Quantum entanglement and squeezing have significantly improved phase estimation and imaging in interferometric settings beyond the classical limits. However, for a wide class of no…
Quantum-enhanced pattern recognition
Giuseppe Ortolano, Carmine Napoli, Cillian Harney +6
The challenge of pattern recognition is to invoke a strategy that can accurately extract features of a dataset and classify its samples. In realistic scenarios this dataset may be…
Quantum readout of imperfect classical data
Giuseppe Ortolano, Ivano Ruo-Berchera
The encoding of classical data in a physical support can be done up to some level of accuracy due to errors and the imperfection of the writing process. Moreover, some degradation…
Phase retrieval enhanced by quantum correlation
Giuseppe Ortolano, Pauline Boucher, Ivano Ruo Berchera +2
Quantum correlation, such as entanglement and squeezing have shown to improve phase estimation in interferometric setups on one side, and non-interferometric imaging scheme of ampl…
Quantum reading: the experimental set-up
Elena Losero, Giuseppe Ortolano, Fabio Saccomandi +3
The protocol of quantum reading refers to the quantum enhanced retrieval of information from an optical memory, whose generic cell stores a bit of information in two possible lossy…
Quantum Conformance Test
Giuseppe Ortolano, Pauline Boucher, Ivo Pietro Degiovanni +3
We introduce a protocol addressing the conformance test problem, which consists in determining whether a process under test conforms to a reference one. We consider a process to be…
Experimental quantum reading with photon counting
Giuseppe Ortolano, Elena Losero, Ivano Ruo Berchera +2
The final goal of quantum hypothesis testing is to achieve quantum advantage over all possible classical strategies. In the protocol of quantum reading this advantage is achieved f…
Quantum Enhanced Imaging of Non-Uniform Refractive Profiles
Giuseppe Ortolano, Ivano Ruo Berchera, Enrico Predazzi
In this work quantum metrology techniques are applied to the imaging of objects with a non-uniform refractive spatial profile. A sensible improvement on the classical accuracy is s…
