Overview

Experimental study demonstrates subelectron readout noise in a thick silicon skipper CCD, indicating broad utility for low-mass dark matter searches and exoplanet imaging.

Key Points

To achieve reproducible subelectron readout noise across large-area charge-coupled devices to enable the discrete counting of single electrons and photons.
Coupled ultralow-noise electronics with repetitive, nondestructive readout on a thick, fully depleted silicon charge-coupled device (CCD).
Measured charge states across millions of detector pixels to evaluate system stability and quantization performance from zero to thousands of electrons.
Achieved a readout noise level of 0.068 e⁻ rms/pixel across a stable, large-area detector.
Demonstrated discrete, quantized charge measurement capable of single-photon counting in the optical and near-infrared regimes.
Established potential for direct application in low-mass dark matter searches, coherent neutrino-nucleus scattering, and exoplanet spectroscopy with minimal impact on CCD fabrication.
