Neural Network Learning of One-Bit Protocols for Qubit Measurement Simulation
Josep Escrig, Mani Zartab, Giulio Gasbarri +3
Communication complexity provides a natural framework for quantifying the classical resources required to reproduce quantum statistics. In the qubit prepare-and-measure scenario, t…

Single-letter Chain Rule for Quantum Relative Entropy
Giulio Gasbarri, Matt Hoogsteder-Riera
Relative entropy is the standard measure of distinguishability in classical and quantum information theory. In the classical case, its loss under channels admits an exact chain rul…

Prepare-and-measure and entanglement simulation beyond qubits
Mani Zartab, Giulio Gasbarri, Gael SentÃs +1
For two non-communicating parties, quantum theory can give rise to probability distributions of outcomes that no local classical model can reproduce without communication. However,…
