qat.hardware.DefaultHardwareModel

class qat.hardware.DefaultHardwareModel(gate_times=None, gate_noise=None, idle_noise=None, channel_repr=ChannelRepresentations.KRAUS)

A default hardware model, with perfect gates and possibility to add idling noise and gate noise. It contains:

gates: instantaneous gates if nothing specified in constructor

environment: noise on idle qubits or nothing if nothing specified

Parameters

gate_times (dict<str, float> or dict<str, dict<tuple<int>, float>> or dict<str, lambda<param, float>> or dict<str, dict<tuple<int>, lambda<param, float>>) – contains duration (possibly parametric) of each gate (possibly qubit-wise)
gate_noise (dict<str, ParametricQuantumChannel or lambda<args, QuantumChannel>>, optional) – specifies the noise to be (optionally) appended after each gate application. Defaults to None (no gate noise).
idle_noise (dict<int, list<ParametricQuantumChannel>> or list<ParametricQuantumChannel>, optional) – specifies the noise to be applied to idle qubits. Default to None (no idle noise).
channel_repr (qat.quops.ChannelRepresentations, optional) – specifies quantum channel representation (e.g Kraus representation or Pauli transfer matrix). Defaults to ChannelRepresentations.KRAUS.

gates_specification

specifies the gates of this hardware.

gate_noise

specifies the noise to be (optionally) appended after each gate application.

idle_noise

specifies the noise to be applied to idle qubits.

Type: dict<int, list<ParametricQuantumChannel>> or list<ParametricQuantumChannel>

params_specification

specifies the parameters that are used in the Schedule fed to an analog QPU.

jump_operators

list of Lindblad jump operators (for analog QPUs).
