Properties of Random Code Ensembles over Classical-Quantum Channels
Giuseppe Cocco, Javier Rodríguez Fonollosa
We show two properties of i.i.d. code ensembles over classical-quantum (CQ) channels with arbitrary output states. The first property is that the probability distribution of the er…
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…
Polar Coding for the Wiretap Broadcast Channel with Multiple Messages
Jaume del Olmo, Javier R. Fonollosa
A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send…
Publicness, Privacy and Confidentiality in the Single-Serving Quantum Broadcast Channel
Farzin Salek, Min-Hsiu Hsieh, Javier R. Fonollosa
The 2-receiver broadcast channel is studied: a network with three parties where the transmitter and one of the receivers are the primarily involved parties and the other receiver c…
Polar Coding for Common Message Only Wiretap Broadcast Channel
Jaume del Olmo Alos, Javier R. Fonollosa
A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send…
One-shot Capacity bounds on the Simultaneous Transmission of Classical and Quantum Information
Farzin Salek, Anurag Anshu, Min-Hsiu Hsieh +2
We study the communication capabilities of a quantum channel under the most general channel model known as the one-shot model. Unlike classical channels that can only be used to tr…
Strong Secrecy on a Class of Degraded Broadcast Channels Using Polar Codes
Jaume del Olmo, Javier R. Fonollosa
Different polar coding schemes are proposed for the memoryless degraded broadcast channel under different reliability and secrecy requirements: layered decoding and/or layered secr…
