John F. Barry, Jennifer M. Schloss, Erik Bauch +4
Solid-state spin systems including nitrogen-vacancy (NV) centers in diamond constitute an increasingly favored quantum sensing platform. However, present NV ensemble devices exhibi…
Hamiltonian Engineering with Constrained Optimization for Quantum Sensing and Control
Michael F. O'Keeffe, Lior Horesh, John F. Barry +2
While quantum devices rely on interactions between constituent subsystems and with their environment to operate, native interactions alone often fail to deliver targeted performanc…
Simultaneous Broadband Vector Magnetometry Using Solid-State Spins
Jennifer M. Schloss, John F. Barry, Matthew J. Turner +1
We demonstrate a vector magnetometer that simultaneously measures all Cartesian components of a dynamic magnetic field using an ensemble of nitrogen-vacancy (NV) centers in a singl…
Ultralong Dephasing Times in Solid-State Spin Ensembles via Quantum Control
Erik Bauch, Connor A. Hart, Jennifer M. Schloss +5
Quantum spin dephasing is caused by inhomogeneous coupling to the environment, with resulting limits to the measurement time and precision of spin-based sensors. The effects of spi…
Mapping the Microscale Origins of MRI Contrast with Subcellular NV Diamond Magnetometry
Hunter C. Davis, Pradeep Ramesh, Aadyot Bhatnagar +5
Magnetic resonance imaging (MRI) is a widely used biomedical imaging modality that derives much of its contrast from microscale magnetic field gradients in biological tissues. Howe…
