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…
A First-principles Computational Framework for Quantum Decoherence in Complex Diamond Spin Environments
Huijin Park, Ha-young Jeong, Hyeonsu Kim +6
Quantum decoherence induced by defects remains a major limitation for solid-state quantum technologies, yet predicting decoherence in realistic materials remains computationally ch…
Overcoming frequency resolution limits using a solid-state spin quantum sensor
Qingyun Cao, Genko T. Genov, Yaoming Chu +4
The ability to determine precisely the separation of two frequencies is fundamental to spectroscopy, yet the resolution limit poses a critical challenge: distinguishing two incoher…
High-Fidelity Single-Shot Readout and Selective Nuclear Spin Control for a Spin-1/2 Quantum Register in Diamond
Prithvi Gundlapalli, Philipp J. Vetter, Genko Genov +5
Quantum networks offer a way to overcome the size and complexity limitations of single quantum devices by linking multiple nodes into a scalable architecture. Group-IV color center…
Weak convexity of Fisher information matrix and superresolved localization of blinking sources of light
Dmitri B. Horoshko, Alexander B. Mikhalychev, Fedor Jelezko +1
A group of techniques known by the general name of single-molecule localization microscopy reaches a nanometer-scale spatial resolution of point light emitters, well below the diff…
Optimization and characterization of laser excitation for quantum sensing with single nitrogen-vacancy centres
Alejandro MartÃnez-Méndez, Jesús Moreno-Meseguer, Mariusz Mrózek +4
In this work we present a comprehensive method of characterization and optimization of laser irradiation within a confocal microscope tailored to quantum sensing experiments using…
