standard_stages#

Full path: iqm.cpc.compiler.standard_stages

Standard compilation stages, their constituent compiler passes, and functions for implementing them.

There are 6 standard compilation stages:

  1. Circuit-to-circuit.

  2. Circuit-to-timebox.

  3. Timebox-to-timebox.

  4. Timebox-to-schedule.

  5. Schedule-to-schedule.

  6. Schedule-to-playlist.

Breakdown of compiler passes of each stage:

1. Circuit-to-circuit#

  1. Map the logical QPU components to physical QPU components. Provided mapping is used, if any. Otherwise, identity mapping is used.

  2. Choose implementations for circuit operations based on the calibration set.

  3. Add additional terminal measurements and/or convert the terminal measurements to the measure_fidelity QuantumOp.

2. Circuit-to-timebox#

  1. Resolve the circuits to timeboxes using ScheduleBuilder.circuit_to_timebox().

3. Timebox-to-timebox#

  1. Merge any MultiplexedProbeTimeBoxes inside each TimeBox using TimeBox.composite().

  2. Add the heralding measurement timebox to all circuits if HeraldingMode in circuit execution options requires it.

  3. Add a reset timebox to all circuits.

4. Timebox-to-schedule#

  1. Resolve the timeboxes to schedules using ScheduleBuilder.resolve_timebox().

5. Schedule-to-schedule#

  1. Apply dynamical decoupling sequences to the schedule if requested.

  2. Apply resonator-related phase corrections if MOVE gates are used.

  3. Remove non-functional instructions from schedules using ScheduleBuilder._finish_schedule().

6. Schedule-to-playlist#

  1. Build the playlist from the schedules using ScheduleBuilder.build_playlist().

Module Attributes

BUFFER_AFTER_MEASUREMENT_PROBE

Buffer that allows the readout resonator and qubit state to stabilize after a probe pulse, in s.

Functions

apply_dd_strategy(schedules, builder, context)

Insert dynamical decoupling sequences into the schedules, if dynamical decoupling is enabled.

apply_move_gate_phase_corrections(schedules, ...)

multiplex_readout(timeboxes, timebox_input)

Merge any MultiplexedProbeTimeBoxes inside a TimeBox representing a circuit.

prepend_heralding(timeboxes, builder, context)
