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…
Quantum Gates via Dynamical Decoupling of Central Qubit on IBMQ and 15NV Center in Diamond
Lucas Tsunaki, Michael Dotan, Kseniia Volkova +1
We demonstrate a hardware-agnostic protocol for realizing fast, high-fidelity gates through dynamical decoupling (DD) pulse sequences applied to a central qubit coupled to target q…
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…
Digital Twin Simulations Toolbox of the Nitrogen-Vacancy Center in Diamond
Lucas Tsunaki, Anmol Singh, Sergei Trofimov +1
The nitrogen-vacancy (NV) center in diamond is a crucial platform for quantum technologies, where its precise numerical modeling is indispensable for the continued advancement of t…
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…
