Upper bounds on the performance of differential-phase-shift quantum key distribution

Hipolito Gomez-Sousa, Marcos Curty

In this paper, we investigate limitations imposed by sequential attacks on the performance of a differential-phase-shift (DPS) quantum key distribution (QKD) protocol with weak coh…

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…
