Practical quantum tokens: challenges and perspectives
Nadezhda P. Kukharchyk, Holger Boche, Christian Deppe +21
The concept of quantum tokens dates back alongside quantum cryptography to Stephen Wiesner's seminal work in 1983[1]. Already this initial work proposes society-relevant applicatio…
Security Analysis of Ensemble-Based Quantum Token Protocol Under Advanced Attacks
Bernd Bauerhenne, Lucas Tsunaki, Jan Thieme +2
We present and characterize advanced attacks on an ensemble-based quantum token protocol that allows for implementing non-clonable quantum coins. Multiple differently initialized t…
Spectroscopic footprints of quantum friction in nonreciprocal and chiral media
O. J. Franca, Fabian Spallek, Steffen M. Giesen +4
We investigate how the quantum friction experienced by a polarizable atom moving with constant velocity parallel to a planar interface is modified when the latter consists of chira…
Ensemble-Based Quantum Token Protocol Benchmarked on IBM Quantum Processors
Lucas Tsunaki, Bernd Bauerhenne, Malwin Xibraku +3
Quantum tokens envision to store unclonable quantum states in a physical device, with the goal of being used for personal authentication protocols, as required by banks. Still, the…
