class QutipI(targets, **kwargs)

Bases: qutip_qip.operations.gateclass.SingleQubitGate

Single-qubit I gate.

Examples

>>> from qutip_qip.operations import X
>>> I(0).get_compact_qobj()
Quantum object: dims=[[2], [2]], shape=(2, 2), type='oper', dtype=Dense, isherm=True
Qobj data =
[[1. 0.]
 [0. 1.]]

name = 'I'

latex_str = 'I'

class QutipBackend(nsteps: int = 10000, noise_model: qilisdk.noise.NoiseModel | None = None)

Bases: qilisdk.backends.backend.Backend

Backend that runs digital-circuit and analog time-evolution experiments using QuTiP.

The backend is CPU-only and has no hardware dependencies, which makes it ideal for local development, CI pipelines, and educational notebooks.

Instantiate a new QutipBackend.

Parámetros:

• nsteps (int) – The maximum number of internal steps for the ODE solver. Defaults to 10_000.

• noise_model (NoiseModel | None) – Optional noise model. For analog time evolution, its global and per-qubit Lindblad channels are converted into QuTiP collapse operators (including time-dependent rates rate(t)). Digital-circuit noise is not supported and is ignored with a warning.

noise_model = None

nsteps = 10000
