14:00-14:40 I Peter Stano Colored correlated noise and quantum computation ΞΞΞ The threshold theorems on which the quantum error correction hinges usually assume uncorrelated noise (both in space and time). In any real device, the noise is, to some degree, correlated (both in space and time). What such correlations imply for the feasibility of quantum computation is largely unknown. I will review our recent work on characterization of noise correlations in current silicon spin qubit hardware [1-4]. It culminates in Ref.[5], where we quantify the spatial extent of noise correlations in a five-qubit silicon array and assess their impact on quantum error correction. We identify two distinct sources of correlated noise: global magnetic field drifts that generate perfectly correlated fluctuations, and charge noise from two-level fluctuators that produces short-range correlations decaying within neighboring qubits. The magnetic drift is an example of noise so strongly correlated that it can compromise quantum error correction. In contrast, the measured charge noise correlations are moderate, electrically tunable, and compatible with fault-tolerant operation with minimal qubit overhead.
