Statistical Complexity of Quantum Learning
Leonardo Banchi, Jason Luke Pereira, Sharu Theresa Jose +1
Recent years have seen significant activity on the problem of using data for the purpose of learning properties of quantum systems or of processing classical or quantum data via qu…
Continuous variable port-based teleportation
Jason L. Pereira, Leonardo Banchi, Stefano Pirandola
Port-based teleportation is generalization of the standard teleportation protocol which does not require unitary operations by the receiver. This comes at the price of requiring $N…
Quantum-enhanced cluster detection in physical images
Jason L. Pereira, Leonardo Banchi, Stefano Pirandola
Identifying clusters in data is an important task in many fields. In this paper, we consider situations in which data live in a physical world, so we have to first collect the imag…
Analytical bounds for non-asymptotic asymmetric state discrimination
Jason L. Pereira, Leonardo Banchi, Stefano Pirandola
Two types of errors can occur when discriminating pairs of quantum states. Asymmetric state discrimination involves minimizing the probability of one type of error, subject to a co…
Bounding the benefit of adaptivity in quantum metrology using the relative fidelity
Jason L. Pereira, Leonardo Banchi, Stefano Pirandola
Protocols for discriminating between a pair of channels or for estimating a channel parameter can often be aided by adaptivity or by entanglement between the probe states. This can…
Generalization in Quantum Machine Learning: a Quantum Information Perspective
Leonardo Banchi, Jason Pereira, Stefano Pirandola
Quantum classification and hypothesis testing are two tightly related subjects, the main difference being that the former is data driven: how to assign to quantum states the…
Idler-free channel position finding
Jason L. Pereira, Leonardo Banchi, Quntao Zhuang +1
Entanglement is a powerful tool for quantum sensing, and entangled states can greatly boost the discriminative power of protocols for quantum illumination, quantum metrology, or qu…
Optimal environment localization
Jason L. Pereira, Quntao Zhuang, Stefano Pirandola
Quantum channels model many physical processes. For this reason, hypothesis testing between quantum channels is a fundamental task in quantum information theory. Here we consider t…
Bounds on amplitude damping channel discrimination
Jason L. Pereira, Stefano Pirandola
Amplitude damping (AD) channels are good models for many physical scenarios, and so the development of protocols to discriminate between them is an important task in quantum inform…
Characterising port-based teleportation as a universal simulator of qubit channels
Jason Pereira, Leonardo Banchi, Stefano Pirandola
Port-based teleportation (PBT) is a teleportation protocol that employs a number of Bell pairs and a joint measurement to enact an approximate input-output identity channel. Replac…
Advances in Quantum Cryptography
S. Pirandola, U. L. Andersen, L. Banchi +15
Quantum cryptography is arguably the fastest growing area in quantum information science. Novel theoretical protocols are designed on a regular basis, security proofs are constantl…
Optimization and learning of quantum programs
Leonardo Banchi, Jason Pereira, Seth Lloyd +1
A programmable quantum processor is a fundamental model of quantum computation. In this model, any quantum channel can be approximated by applying a fixed universal quantum operati…
Convex optimization of programmable quantum computers
Leonardo Banchi, Jason Pereira, Seth Lloyd +1
A fundamental model of quantum computation is the programmable quantum gate array. This is a quantum processor that is fed by a program state that induces a corresponding quantum o…
Hacking Alice's box in CV-QKD
Jason Pereira, Stefano Pirandola
Security analyses of quantum cryptographic protocols typically rely on certain conditions; one such condition is that the sender (Alice) and receiver (Bob) have isolated devices in…
Fundamental limits to quantum channel discrimination
Stefano Pirandola, Riccardo Laurenza, Cosmo Lupo +1
What is the ultimate performance for discriminating two arbitrary quantum channels acting on a finite-dimensional Hilbert space? Here we address this basic question by deriving a g…
