interleaved_gate_fidelity_bounds
(irb_decay, rb_decay, dim, unitarity=None)¶ Use observed rb_decay to place a bound on fidelity of a particular gate with given interleaved rb decay. Optionally, use unitarity measurement result to provide improved bounds on the interleaved gate’s fidelity.
Bounds are due to [IRB]. Improved bounds using unitarity are due to [U+IRB]
[U+IRB] Efficiently characterizing the total error in quantum circuits. Dugas et al. arXiv:1610.05296 (2016). https://arxiv.org/abs/1610.05296 Parameters: - irb_decay – Observed decay parameter in irb experiment with desired gate interleaved between Cliffords
- rb_decay – Observed decay parameter in standard rb experiment
- dim – Dimension of the Hilbert space, 2**num_qubits
- unitarity – Observed decay parameter in unitarity experiment; improves bounds if provided.
Returns: The pair of lower and upper bounds on the fidelity of the interleaved gate.
