Bounds in Sequential Unambiguous Discrimination of Multiple Pure Quantum States
Jordi Pérez-Guijarro, Alba Pagès-Zamora, Javier R. Fonollosa
Sequential methods for quantum hypothesis testing offer significant advantages over fixed-length approaches, which rely on a predefined number of state copies. Despite their potent…
Extension of Clifford Data Regression Methods for Quantum Error Mitigation
Jordi Pérez-Guijarro, Alba Pagès-Zamora, Javier R. Fonollosa
To address the challenge posed by noise in real quantum devices, quantum error mitigation techniques play a crucial role. These techniques are resource-efficient, making them suita…
Relation between quantum advantage in supervised learning and quantum computational advantage
Jordi Pérez-Guijarro, Alba Pagès-Zamora, Javier R. Fonollosa
The widespread use of machine learning has raised the question of quantum supremacy for supervised learning as compared to quantum computational advantage. In fact, a recent work s…
Multi-qubit time-varying quantum channels for NISQ-era superconducting quantum processors
Josu Etxezarreta Martinez, Patricio Fuentes, Antonio deMarti iOlius +3
Recent experimental studies have shown that the relaxation time () and the dephasing time () of superconducting qubits fluctuate considerably over time. To appropriately…
Generalized Perfect Codes for Symmetric Classical-Quantum Channels
Andreu Blasco Coll, Gonzalo Vazquez-Vilar, Javier R. Fonollosa
We define a new family of codes for symmetric classical-quantum channels and establish their optimality. To this end, we extend the classical notion of generalized perfect and quas…
