braket.default_simulator.openqasm.circuit module

class braket.default_simulator.openqasm.circuit.Circuit(instructions: list[GateOperation] | None = None, results: list[Amplitude | Expectation | Probability | Sample | StateVector | DensityMatrix | Variance | AdjointGradient] | None = None)[source]

Bases: object

This is a lightweight analog to braket.ir.jaqcd.program_v1.Program. The Interpreter compiles to an IR to hand off to the simulator, braket.default_simulator.state_vector_simulator.StateVectorSimulator, for example. Our simulator module takes in a circuit specification that satisfies the interface implemented by this class.

add_instruction(instruction: GateOperation | KrausOperation) → None[source]

Add instruction to the circuit.

Parameters:: instruction (GateOperation) – Instruction to add.

add_measure(target: tuple[int], classical_targets: Iterable[int] | None = None, allow_remeasure: bool = False)[source]

add_result(result: Amplitude | Expectation | Probability | Sample | StateVector | DensityMatrix | Variance | AdjointGradient) → None[source]

Add result type to the circuit.

Parameters:: result (Results) – Result type to add.

property num_qubits: int

property basis_rotation_instructions: Basis rotation instructions implied by the provided observables
