Color-Center-Compatible Freestanding Diamond Directional Couplers for Quantum Photonics
Colin Sauerzapf, Tom Jäger, Jonathan EnÃlin +6
Freestanding all-diamond color-center photonics is a promising platform for optical integration of spin-based quantum defects. Within this geometry, we realize a key building block…
Enhanced security in Quantum Token protocols using Hybrid Spin-Photon Interfaces
Durga Bhaktavatsala Rao Dasari, Yang Wang, Jörg Wrachtrup
Quantum token protocols enable unforgeable quantum tokens promising unconditional security beyond classical cryptographic assumptions. We show here that the three stages of the Qua…
