Intro to Quantum Noise (main lecture)
Part of the series Intro to Quantum Noise (QGSS 2023); cited as one entry below.
Starts from a 'Hello World' circuit of repeated X gates whose ideal output alternates with depth, then compares it with real device data to motivate the study of noise. Works through miscalibrated gates as coherent errors, incoherent noise, projection noise and SPAM, and closes with how error mitigation and error correction address noise, with bonus material on ZZ crosstalk and the readout A matrix.
- Coherent over-rotation errors and why their worst-case impact grows quadratically with depth
- Incoherent noise and quantum projection (shot) noise
- State-preparation and measurement (SPAM) errors and the readout assignment matrix
- Overview of error mitigation versus error correction; bonus two-qubit ZZ error notebook
Summary and key points drafted by a language model from the slides, not yet reviewed by me. The slides are the source.
