Near-limit quantum control beyond analytic tractability in many-body spin systems
Jixing Zhang, Bo Peng, Yang Wang +11
As quantum control approaches hardware-imposed performance limits, weak effects omitted by reduced models become consequential. Assumptions required for analytic tractability then…
Optically Addressable Molecular Spins at 2D Surfaces
Xuankai Zhou, Yan-Tung Kong, Cheuk Kit Cheung +18
Optically addressable spins at material surfaces have represented a long-standing ambition in quantum sensing, providing atomic resolution and quantum-limited sensitivity. However,…
Deformation-Driven Enhancement of Spin Defect Emission in Hexagonal Boron Nitride
Jianpei Geng, Xuankai Zhou, Nils Gross +11
The negatively charged boron vacancy (VB-) in hexagonal boron nitride (hBN) has been extensively investigated as it offers a novel playground for two-dimensional quantum sensing, w…
Strain Enhanced Spin Readout Contrast in Silicon Carbide Membranes
Haibo Hu, Guodong Bian, Ailun Yi +12
Quantum defects in solids have emerged as a transformative platform for advancing quantum technologies. A key requirement for these applications is achieving high-fidelity single-s…
Theory of optical spin polarization of axial divacancy and nitrogen-vacancy defects in 4H-SiC
Guodong Bian, GergÅ Thiering, Ãdám Gali
The neutral divacancy and the negatively charged nitrogen-vacancy defects in 4H-silicon carbide (SiC) are two of the most prominent candidates for functioning as room-temperature q…
