Quantum Nanophotonic Interface for Tin-Vacancy Centers in Thin-Film Diamond
Hope Lee, Hannah C. Kleidermacher, Abigail J. M. Stein +10
The negatively charged tin-vacancy center in diamond (SnV) is an excellent solid state qubit with optically-addressable transitions and a long electron spin coherence time at e…
Detecting quantum noise of a solid-state spin ensemble with dispersive measurement
Mikhail Mamaev, Jayameenakshi Venkatraman, Martin Koppenhöfer +2
We theoretically explore protocols for measuring the spin polarization of an ensemble of solid-state spins, with precision at or below the standard quantum limit. Such measurements…
Creation of Depth-Confined, Shallow Nitrogen-Vacancy Centers in Diamond With Tunable Density
Lillian B. Hughes Wyatt, Shreyas Parthasarathy, Isaac Kantor +6
Engineering shallow nitrogen-vacancy (NV) centers in diamond holds the key to unlocking new advances in nanoscale quantum sensing. We find that the creation of near-surface NVs thr…
Dressed-state Hamiltonian engineering in a strongly interacting solid-state spin ensemble
Haoyang Gao, Nathaniel T. Leitao, Siddharth Dandavate +7
In quantum science applications, ranging from many-body physics to quantum metrology, dipolar interactions in spin ensembles are controlled via Floquet engineering. However, this t…
Collective many-body dynamics in a solid-state quantum sensor controlled through nanoscale magnetic gradients
Piotr Put, Nathaniel T. Leitao, Haoyang Gao +13
Coherent collective dynamics of strongly interacting qubits are a central resource in quantum information science, with applications from quantum computing and simulation to metrol…
Patterning programmable spin arrays on DNA origami for quantum technologies
Zhiran Zhang, Taylor Morrison, Lillian Hughes +6
The controlled assembly of solid-state spins with nanoscale spatial precision is an outstanding challenge for quantum technology. Here, we combine DNA-based patterning with nitroge…
