qiskit.pulse.instructions
The instruction module holds the various Instruction s which are supported by Qiskit Pulse. Instructions have operands, which typically include at least one Channel specifying where the instruction will be applied.
Every instruction has a duration, whether explicitly included as an operand or implicitly defined. For instance, a ShiftPhase instruction can be instantiated with operands phase and channel, for some float phase and a Channel channel:
ShiftPhase(phase, channel)The duration of this instruction is implicitly zero. On the other hand, the Delay instruction takes an explicit duration:
Delay(duration, channel)An instruction can be added to a Schedule, which is a sequence of scheduled Pulse Instruction s over many channels. Instruction s and Schedule s implement the same interface.
Acquire(duration, channel[, mem_slot, …]) | The Acquire instruction is used to trigger the ADC associated with a particular qubit; e.g. |
Delay(duration, channel[, name]) | A blocking instruction with no other effect. |
Play(pulse, channel[, name]) | This instruction is responsible for applying a pulse on a channel. |
SetFrequency(frequency, channel[, name]) | Set the channel frequency. |
ShiftFrequency(frequency, channel[, name]) | Shift the channel frequency away from the current frequency. |
SetPhase(phase, channel[, name]) | The set phase instruction sets the phase of the proceeding pulses on that channel to phase radians. |
ShiftPhase(phase, channel[, name]) | The shift phase instruction updates the modulation phase of proceeding pulses played on the same Channel. |
Snapshot(label[, snapshot_type, name]) | An instruction targeted for simulators, to capture a moment in the simulation. |
Abstract Classes
Instruction(operands, duration, channels[, name]) | The smallest schedulable unit: a single instruction. |
