Quantum Error Mitigation, Lecture 3
Part of the series Quantum Error Mitigation (Boulder Summer School 2023); cited as one entry below.
The third lecture puts error mitigation to work: map Ising time evolution to Trotter circuits, decompose into native-gate layers, learn the noise per layer, and cancel it with PEC, comparing results with and without mitigation on up to 50-qubit observables. It then looks at runtime scaling with scale, quality and speed, and closes with a many-body experiment on 124 qubits that reconstructs local integrals of motion (LIOMs) in a 2D Floquet system.
- Trotterized transverse-field Ising circuits: RZZ/RX decomposition and 2Q gate layers
- PEC workflow: layer noise learning, Pauli twirling, sampled inverse; with vs. without PEC
- PEC runtime exponential in qubits and depth; scale, quality, speed
- LIOMs, spin imbalance, and prethermal vs. thermalizing regimes on 124Q, depth-60 circuits
