Story summary
  • Key Information: Researchers at the Niels Bohr Institute, led by Dr. Fabrizio Berritta, developed a monitoring system that detects qubit changes, shifting from stable to unstable in milliseconds.
  • The approach combines commercially available hardware with innovative measurement strategies to enable real-time qubit monitoring using a Field-Programmable Gate Array (FPGA).
  • The findings show that a good qubit can quickly become bad, underscoring need to understand qubit fluctuations for scaling quantum processors.
