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…
Wideband covariance magnetometry below the diffraction limit
Xuan Hoang Le, Pavel E. Dolgirev, Piotr Put +6
We experimentally demonstrate a method for measuring correlations of wideband magnetic signals with spatial resolution below the optical diffraction limit. Our technique employs tw…
Signal amplification in a solid-state quantum sensor via asymmetric time-reversal of many-body dynamics
Haoyang Gao, Leigh S. Martin, Lillian B. Hughes +8
Electronic spins of nitrogen vacancy (NV) centers in diamond constitute a promising system for micro- and nano-scale magnetic sensing, due to their operation under ambient conditio…
