qv_circuits
(qubit_lists, ntrials=1, qr=None, cr=None, seed=None)[source]¶ Return a list of square quantum volume circuits (depth=width)
The qubit_lists is specified as a list of qubit lists. For each set of qubits, circuits the depth as the number of qubits in the list are generated
 Parameters
qubit_lists (list) – list of list of qubits to apply qv circuits to. Assume the list is ordered in increasing number of qubits
ntrials (int) – number of random iterations
qr (QuantumRegister) – quantum register to act on (if None one is created)
cr (ClassicalRegister) – classical register to measure to (if None one is created)
seed (int) – An optional RNG seed to use for the generated circuit
 Returns
 A tuple of the type (
circuits
,circuits_nomeas
) wheere: circuits
is a list of lists of circuits for the qv sequences (separate list for each trial) and `` circuitss_nomeas`` is the same circuits but with no measurements for the ideal simulation
 A tuple of the type (
