Quantum Vault: Symmetric No-Cloning Protection for Token Issuer and User (Benchmarked on IBMQ)

Lucas Tsunaki, Boris Naydenov

Quantum tokens are underlying primitives for quantum money and network proposals, which leverage the no-cloning theorem to realize unforgeable authentication. A relevant but overlo…

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…

Local nanoscale probing of electron spins using NV centers in diamond

Sergei Trofimov, Christos Thessalonikios, Victor Deinhart +5

Substitutional nitrogen atoms in a diamond crystal (P1 centers) are, on one hand, a resource for creation of nitrogen-vacancy (NV) centers, that have been widely employed as nanosc…
