Coupling

Hyperfine 

Hyperfine(parent=None)

Bases: LevelCoupling

This node represents level coupling between hyperfine states.

Examples:

- To reach the node from the start node:

>>> node = bloqade.start.hyperfine
>>> type(node)
<class 'bloqade.builder.coupling.Hyperfine'>

- Hyperfine level coupling has two reachable field nodes:

    - detuning term (See also [`Detuning`][bloqade.builder.field.Detuning])
    - rabi term (See also [`Rabi`][bloqade.builder.field.Rabi])

>>> hyp_detune = bloqade.start.hyperfine.detuning
>>> hyp_rabi = bloqade.start.hyperfine.rabi

__bloqade_ir__ 

__bloqade_ir__()

Generate the intermediate representation (IR) for the Hyperfine level coupling.

Returns:

Name Type Description
IR

An intermediate representation of the Hyperfine level coupling sequence.
Note

This method is used internally by the Bloqade framework.

detuning property 

detuning

Specify the [Detuning][bloqade.builder.field.Detuning] [Field][bloqade.builder.field.Field] of your program. You will be able to specify the spatial modulation afterwards.

Returns:

Type Description
Detuning

[Detuning][bloqade.builder.field.Detuning]: A program node representing the detuning field.
Note

The detuning specifies how off-resonant the laser being applied to the atoms is from the atomic energy transition, driven by the Rabi frequency.

Example: 

from bloqade import start
geometry = start.add_position((0,0))
coupling = geometry.rydberg
coupling.detuning

  • Next Possible Steps You may continue building your program via:
  • [uniform][bloqade.builder.field.Detuning.uniform]: To address all atoms in the field
  • [location(locations, scales)][bloqade.builder.field.Detuning.location]: To address atoms at specific locations via indices
  • [scale(coeffs)][bloqade.builder.field.Detuning.scale]: To address all atoms with an individual scale factor

rabi property 

rabi

Specify the complex-valued [Rabi][bloqade.builder.field.Rabi] field of your program.

The Rabi field is composed of a real-valued Amplitude and Phase field.

Returns:

Name Type Description
Rabi Rabi

A program node representing the Rabi field.
Note

Next possible steps to build your program are creating the RabiAmplitude field and RabiPhase field of the field: - ...rabi.amplitude: To create the Rabi amplitude field - ...rabi.phase: To create the Rabi phase field

Rydberg 

Rydberg(parent=None)

Bases: LevelCoupling

This node represents level coupling of the Rydberg state.

Examples:

- To reach the node from the start node:

>>> node = bloqade.start.rydberg
>>> type(node)
<class 'bloqade.builder.coupling.Rydberg'>

- Rydberg level coupling has two reachable field nodes:

    - detuning term (See also [`Detuning`][bloqade.builder.field.Detuning])
    - rabi term (See also [`Rabi`][bloqade.builder.field.Rabi])

>>> ryd_detune = bloqade.start.rydberg.detuning
>>> ryd_rabi = bloqade.start.rydberg.rabi
