qiskit.ignis.verification.QOTP

QOTP(circ, num, two_qubit_gate='cx', coupling_map=None, seed=None)

Performs a QOTP (or random compilation) on a generic circuit.

This is similar to randomized compiling, but follows the methods in [1].

Parameters

• circ (QuantumCircuit) – A generic quantum circuit
• num (int) – the number of one-time pads to return
• two_qubit_gate (string) – a flag as to which 2 qubit gate to compile with, can be cx or cz
• coupling_map (list) – a particular device topology as a list of list (e.g. [[0,1],[1,2],[2,0]])
• seed (int) – seed to the random number generator

Returns

a tuple of type (qotp_circ, qotp_postp) where:

qotp_circs (list): a list of circuits with qotp applied qotp_postps (list): a list of arrays specifying the one time pads

Return type

tuple
