Circuit#

class cuquantum.stabilizer.Circuit(
circuit: str | stim.Circuit,
stream: int | cp.cuda.Stream | None = None,
options: Options | None = None,
)[source]#

Represents a quantum circuit for the frame simulator.

This class wraps a circuit defined in Stim-compatible string format. The circuit owns the device buffer where the circuit data is stored.

Parameters:

  • circuit_string – Stim-compatible circuit string representation.

  • stream – Optional CUDA stream.

  • options – Optional Options object for configuration.

Example

>>> circuit = Circuit("H 0\nCNOT 0 1\nM 0 1")
>>> # Or with options
>>> options = Options(device_id=0)
>>> circuit = Circuit("H 0\nCNOT 0 1", options=options)

Methods

__init__(
circuit: str | stim.Circuit,
stream: int | cp.cuda.Stream | None = None,
options: Options | None = None,
