qoolqit.drive

source module qoolqit.drive

Classes

source dataclass WeightedDetuning(weights: dict[Any, float], waveform: Waveform)

A weighted detuning.

See https://pasqal-io.github.io/qoolqit/latest/theory/rydberg_model/#weighted-detuning for details on weighted detunings.

Note: detuning with positive waveforms cannot be instantiated.

Attributes

  • weights : dict[Any, float] — Association of weights to qubits.

  • waveform : Waveform — The waveform for this detuning.

source class Drive(*args: Any, amplitude: Waveform | None = None, detuning: Waveform | None = None, weighted_detunings: list[WeightedDetuning] | None = None, phase: float = 0.0)

The drive Hamiltonian acting over a duration.

Default constructor for the Drive.

Must be instantiated with keyword arguments. Accepts either an amplitude waveform, a detuning waveform, or both. A phase value can also be passed.

Parameters

  • amplitude : Waveform | None — waveform representing Ω(t) in the drive Hamiltonian.

  • detuning : Waveform | None — waveform representing δ(t) in the drive Hamiltonian.

  • phase : float — phase value ɸ for the amplitude term.

  • weighted_detunings : list[WeightedDetuning] | None — additional waveforms and weights applied to individual qubits. Note that these detunings are not supported on all devices.

Attributes

  • amplitude : Waveform — The amplitude waveform in the drive.

  • detuning : Waveform — The detuning waveform in the drive.

  • weighted_detunings : Sequence[WeightedDetuning] — Detunings applied to individual qubits.

  • phase : float — The phase value in the drive.
