qrunch.quantum.backends.qunasys.qulacs_backend

Module with implementation of the Qulacs simulator.

Classes

QulacsBackend

Class for handling Qulacs local simulator.

class QulacsBackend

Bases: Backend

Class for handling Qulacs local simulator.

Requirements:

• Machine: linux-x86_64 or darwin-arm64

__init__(transpiler: Transpiler[QuantumCircuit] | None = None) → None

Initialize a local Qulacs Backend.

The backend calculates the full state vector of the given circuit, and uses this to find the probabilities for each possible state in the Hilbert space.

Parameters:

transpiler (Transpiler[QuantumCircuit] | None) – Transpiler for converting circuits into a format suitable for the backend.

Return type:

None

property name: str

Name of the backend.

run(circuits: Circuit | Sequence[Circuit], shots: int | None) → SimulatedJob

Run circuit on the backend.

Parameters:

• circuits (Circuit | Sequence[Circuit]) – circuits to run on backend

• shots (int | None) – number of shots

Return type:

SimulatedJob

validate_shots_type(shots_type: Type[int | None]) → list[str]

Validate that the sampler supports the given shots type. Return a list of error messages if not supported.

Parameters:

shots_type (Type[int | None])

Return type:

list[str]
