New research proves quantum computing errors correlated, ties them to cosmic rays

In experiments performed at the University of Wisconsin-Madison, researchers found that fluctuations in the electrical charge of multiple quantum bits (qubits) can be highly correlated. The team also linked tiny error-causing perturbations in the qubits’ charge state to the absorption of cosmic rays.
