Quantum sequential parameter testing
Simon Morelli, Ricard Ravell Rodríguez, 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…
Prepare-and-measure and entanglement simulation beyond qubits
Mani Zartab, Giulio Gasbarri, Gael Sentís +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 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…
Quantum Edge Detection
Santiago Llorens, Walther González, Gael Sentís +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…
Quantum multi-anomaly detection
Santiago Llorens, Gael Sentís, Ramon Muñoz-Tapia
A source assumed to prepare a specified reference state sometimes prepares an anomalous one. We address the task of identifying these anomalous states in a series of preparatio…
Identification of malfunctioning quantum devices
M. Skotiniotis, Santiago Llorens, R. Hotz +2
We consider the problem of correctly identifying a malfunctioning quantum device that forms part of a network of such devices, which can be considered as the quantum analogue o…
Optimal parameter estimation with a fixed rate of abstention
B. Gendra, E. Ronco-Bonvehi, J. Calsamiglia +2
The problems of optimally estimating a phase, a direction, and the orientation of a Cartesian frame (or trihedron) with general pure states are addressed. Special emphasis is put o…
Angular Correlations and Light Gluinos in Multi-jet Photoproduction at HERA
R. Muñoz-Tapia, W. J. Stirling
A study of jet event photoproduction at HERA is presented. We define an angular variable which is sensitive to the topology of the final state jets and is therefore able to d…
Light Gluinos in Four-Jet Events at LEP
R. Muñoz-Tapia, W. J. Stirling
The light gluino hypothesis can explain the apparent incompatibility between the measurements of $\as$ at low- and high-energy. Such gluinos are produced directlyin four-jet events…
