Quantum sequential parameter testing
Simon Morelli, Ricard Ravell RodrÃguez, John Calsamiglia +3
Sequential strategies in hypothesis testing use a variable number of measurement rounds, allowing a decision to be made as soon as the observed data provide a prescribed level of e…
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…
Exact identification of unknown unitary processes
Santiago Llorens, Arnau Diebra, Michal Sedlák +1
The accurate identification of faulty hardware is a fundamental requirement for reliable quantum information processing. We address this problem in a quantum setting, where a serie…
Quantum state exclusion for group-generated ensembles of pure states
Arnau Diebra, Santiago Llorens, Emili Bagan +2
Quantum state exclusion is the task of determining which states from a given set a system was not prepared in. We provide a complete solution to optimal quantum state exclusion for…
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,…
Quantum Edge Detection
Santiago Llorens, Walther González, Gael SentÃs +3
This paper introduces quantum edge detection, aimed at locating boundaries of quantum domains where all particles share the same pure state. Focusing on the 1D scenario of a string…
