High-cooperativity coupling and spin-resolved extinction of tin-vacancy centers in a diamond-like microcavity
Kerim Köster, András Laukó, Federico Rapisarda +16
The tin-vacancy (SnV) center in diamond is a promising spin-photon interface for quantum networks, combining favorable optical properties with spin coherence above 1K. Unfolding th…
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…
High-fidelity control of a C nuclear spin coupled to a tin-vacancy center in diamond
Jeremias Resch, Ioannis Karapatzakis, Mohamed Elshorbagy +9
Nuclear spins near group-IV defects in diamond are promising candidates for quantum memories in quantum network applications. Here, we demonstrate high-fidelity control of a single…
Cavity enhancement of V2 centers in 4H-SiC with a fiber-based Fabry-Pérot microcavity
Jannis Hessenauer, Jonathan Körber, Misagh Ghezellou +5
Silicon vacancy centers in 4H-silicon carbide (SiC) host a long-lived electronic spin and simultaneously possess spin-resolved optical transitions, making them a great candidate fo…
Investigation of Purcell enhancement of quantum dots emitting in the telecom O-band with an open fiber-cavity
Julian Maisch, Jonas Grammel, Nam Tran +4
Single-photon emitters integrated in optical micro-cavities are key elements in quantum communication applications. However, optimizing their emission properties and achieving effi…
Microwave Control of the Tin-Vacancy Spin Qubit in Diamond with a Superconducting Waveguide
Ioannis Karapatzakis, Jeremias Resch, Marcel Schrodin +10
Group-IV color centers in diamond are promising candidates for quantum networks due to their dominant zero-phonon line and symmetry-protected optical transitions that connect to co…
Cavity-mediated collective emission from few emitters in a diamond membrane
Maximilian Pallmann, Kerim Köster, Yuan Zhang +5
When an ensemble of quantum emitters couples to a common radiation field, their polarizations can synchronize and a collective emission termed superfluorescence can occur. Entering…
