AutoRebase2QuditGatePass

class AutoRebase2QuditGatePass(max_depth=3, max_retries=-1, success_threshold=1e-08, cost=<bqskit.ir.opt.cost.functions.residuals.hilbertschmidt.HilbertSchmidtResidualsGenerator object>, instantiate_options={})

Bases: Rebase2QuditGatePass

The AutoRebase2QuditGatePass class.

Will use instantiation to change the a 2-qudit gate to a different one.

__init__(max_depth=3, max_retries=-1, success_threshold=1e-08, cost=<bqskit.ir.opt.cost.functions.residuals.hilbertschmidt.HilbertSchmidtResidualsGenerator object>, instantiate_options={})

Construct a AutoRebase2QuditGatePass.

Parameters:

• max_depth (int) – The maximum number of new gates to replace an old gate with. (Default: 3)

• max_retries (int) – The number of retries for the same gate before we increase the maximum depth. If left as -1, then never increase max depth. (Default: -1)

• success_threshold (float) – The distance threshold that determines successful termintation. Measured in cost described by the hilbert schmidt cost function. (Default: 1e-8)

• cost (CostFunction | None) – The cost function that determines successful removal of a gate. (Default: HilbertSchmidtResidualsGenerator())

• (dict[str (instantiate_options) – Any]): Options passed directly to circuit.instantiate when instantiating circuit templates. (Default: {})

Raises:

ValueError – if max_depth is nonnegative.
