New encoding schemes for quantum authentication
Priscila Garcia-Fernandez, Enrique Fernandez-Martinez, Esther Perez +1
We study the potential of general quantum operations, Trace-Preserving Completely-Positive Maps (TPCPs), as encoding and decoding mechanisms in quantum authentication protocols. Th…
Quantum authentication with unitary coding sets
Esther Perez, Marcos Curty, David J. Santos +1
A general class of authentication schemes for arbitrary quantum messages is proposed. The class is based on the use of sets of unitary quantum operations in both transmission and r…
Qubit authentication
Marcos Curty, David J. Santos, Esther Perez +1
Secure communication requires message authentication. In this paper we address the problem of how to authenticate quantum information sent through a quantum channel between two com…
Quantum authentication of classical messages
Marcos Curty, David J. Santos
Although key distribution is arguably the most studied context on which to apply quantum cryptographic techniques, message authentication, i.e., certifying the identity of the mess…
Quantum information processing: A linear systems perspective
Marcos Curty, David J. Santos
In this paper a system-oriented formalism of Quantum Information Processing is presented. Its form resembles that of standard signal processing, although further complexity is adde…
Quantum cryptography without a quantum channel
Marcos Curty, David J. Santos
This paper has been withdrawn by the authors because the results obtained have been reported earlier by other authors.
