A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, “non-Gaussian” noise processes that are routinely encountered in superconducting quantum computers.
The characterization of complex noise in quantum computers is a critical step toward making the quantum systems more precise.
Future research will move from a single-sensor system to a two-sensor system, enabling the characterization of noise correlations across different qubits. (Nature)
