How entangled is each quantum computer today?

The same Bell test runs on every IBM processor we can reach. The daily S per chip shows how clean each machine's entanglement is, and over months it tracks how fast quantum hardware is improving.

Reading the bars
  • 2The classical limit. Anything at or below it could be faked by ordinary physics.
  • 2√2The quantum maximum, 2.828. Perfect qubits would land here.
  • ▬The bright bar is the violation: how far above the classical limit the chip went.
  • ±White ticks: statistical uncertainty from 1,024 shots per setting.

History starts today and is posted daily on X with the chart.
