qoqo.operations.PragmaOverrotation

class qoqo.operations.PragmaOverrotation

The statistical overrotation PRAGMA operation.

This PRAGMA applies a statistical overrotation to the next rotation gate in the circuit, which matches the hqslang name in the gate parameter of PragmaOverrotation and the involved qubits in qubits.

The applied overrotation corresponds to adding a random number to the rotation angle. The random number is drawn from a normal distribution with mean 0 and standard deviation variance and is multiplied by the amplitude.

Parameters:

gate (str) – The unique hqslang name of the gate to overrotate.
qubits (list[int]) – The qubits of the gate to overrotate.
amplitude (float) – The amplitude the random number is multiplied by.
variance (float) – The standard deviation of the normal distribution the random number is drawn from.
