cirq.SuperconductingQubitsNoiseProperties

Noise-defining properties for a superconducting-qubit-based device.

    gate_times_ns: dict[type, float],
    t1_ns: dict[cirq.Qid, float],
    tphi_ns: dict[cirq.Qid, float],

    validate: bool = True
)

gate_times_ns dict[type, float] of gate types to their duration on quantum hardware. Used with t(1|phi)_ns to specify thermal noise.
t1_ns dict[cirq.Qid, float] of qubits to their T_1 time, in ns.
tphi_ns dict[cirq.Qid, float] of qubits to their T_phi time, in ns.
readout_errors dict[cirq.Qid, list[float]] of qubits to their readout errors in matrix form: [P(read |1> from |0>), P(read |0> from |1>)]. Used to prepend amplitude damping errors to measurements.
gate_pauli_errors dict of noise_utils.OpIdentifiers (a gate and the qubits it targets) to the Pauli error for that operation. Used to construct depolarizing error. Keys in this dict must have defined qubits.
validate If True, verifies that t1 and tphi qubits sets match, and that all symmetric two-qubit gates have errors which are symmetric over the qubits they affect. Defaults to True.
