Single-shot latched readout of a quantum dot qubit using barrier gate pulsing

1 min read

Demonstrates single-shot latched readout and accelerated reset of a Si/SiGe quantum-dot hybrid qubit using dynamic barrier-gate control with one reservoir.

Key Results

  • Separates the two logical-state distributions with readout SNR 10.2.
  • Achieves 98% reset/initialization probability after 2 ms, versus 80% without reset pulses.
  • Reports a 15-fold reset speedup while retaining coherent Larmor-oscillation measurements.
