quri_parts.backend.devices.star_device module

generate_device_property(qubit_count, code_distance, qec_cycle, physical_error_rate=0.0, data_total_qubit_ratio=4.0)

Generate DeviceInfo object for STAR architecture devices.

Parameters:
  • qubit_count (int) – Number of logical qubits.

  • physical_error_rate (float) – Error rate of physical qubit operations.

  • code_distance (int) – Code distance of the quantum error correction code.

  • qec_cycle (TimeValue) – Time duration of each syndrome measurement for quantum error correction (without code distance dependency).

  • data_total_qubit_ratio (float) – Ratio of number of total logical qubits to number of data logical qubits.

Returns:

DeviceInfo object representing the target STAR architecture device.

Return type:

DeviceProperty
