- Abstract summary: Current quantum platforms in experimental atomic and optical physics based on CMOS sensors and CCD cameras are limited by either low sensitivity or slow operational speed.
Here we integrate an array of single-photon avalanche diodes with solid-state spin defects in diamond to build a fast wide-field quantum sensor, achieving a frame rate up to 100kHz.
A few exemplary applications, including sensing DC and AC magnetic fields, temperature, strain, local spin density, and charge dynamics, are experimentally demonstrated using an NV ensemble diamond sample.

- Abstract: Achieving fast, sensitive, and parallel measurement of a large number of
quantum particles is an essential task in building large-scale quantum
platforms for different quantum information processing applications such as
sensing, computation, simulation, and communication. Current quantum platforms
in experimental atomic and optical physics based on CMOS sensors and CCD
cameras are limited by either low sensitivity or slow operational speed. Here
we integrate an array of single-photon avalanche diodes with solid-state spin
defects in diamond to build a fast wide-field quantum sensor, achieving a frame
rate up to 100~kHz. We present the design of the experimental setup to perform
spatially resolved imaging of quantum systems. A few exemplary applications,
including sensing DC and AC magnetic fields, temperature, strain, local spin
density, and charge dynamics, are experimentally demonstrated using an NV
ensemble diamond sample. The developed photon detection array is broadly
applicable to other platforms such as atom arrays trapped in optical tweezers,
optical lattices, donors in silicon, and rare earth ions in solids.
