A non-Markovian approach to spin-phonon coherence and the breakdown of the Markovian approximation
Mohamed Belhassen, Tim Schröder, Gregor Pieplow
Qubit coherence is an essential figure of merit for quantum information processing applications such as quantum computing, or quantum repeaters. Understanding the coherence propert…
Quantum Secure Authentication with Color Centers in Diamond
Yannick Strocka, Mohamed Belhassen, Tim Schröder +1
We present a quantum token scheme in which the token is a quantum state that ensures secure authentication or payment. In our approach, rooted in Wiesner's quantum money concept, a…
Optical probing of phononic properties of a tin-vacancy color center in diamond
Cem Güney Torun, Joseph H. D. Munns, Franziska Marie Herrmann +12
The coherence characteristics of a tin-vacancy color center (SnV) in diamond are investigated through optical means, including linewidth broadening effects and coherent population…
Quantum Networks Using Color Defects in Diamond: Principles, Progress, and Perspectives
Ayan Majumder, Cem Güney Torun, Tim Schröder +3
Large-scale quantum networks will enable entirely new applications of quantum information science in fields such as quantum communication, distributed quantum computing, sensing, a…
SUPER and femtosecond spin-conserving coherent excitation of a tin-vacancy color center in diamond
Cem Güney Torun, Mustafa Gökçe, Thomas K. Bracht +11
The coherent excitation of an optically active spin system is one of the key elements in the engineering of a spin-photon interface. Using the novel SUPER scheme, we coherently con…
Secure authentication via Quantum Physical Unclonable Functions: a review
Pol Julià Farré, Vladlen Galetsky, Mohamed Belhassen +6
Quantum Physical Unclonable Functions (QPUFs) offer a physically grounded approach to secure authentication, extending the capabilities of classical PUFs. This review covers their…
