3.3. Clifford Circuit#

CliffordCircuit is the high level API to assemble gates and layers, and it automatically calculate number of qubits in the system It has attributes:

  • first_layer

  • last_layer

  • forward_map

  • backward_map

When CliffordCircuit is initialized, a null CliffordLayer() will be initiated. CliffordCircuit can take CliffordGate by circ.take(gate).

If the gate is independent from the current layer, it will be added. Otherwise, the circuit will create a new layer and add the gate.

circ = circuit.CliffordCircuit()

circ.take(circuit.CliffordGate(0,1))

CliffordCircuit(
  |[0,1]|)

circ.take(circuit.CliffordGate(9,10))

CliffordCircuit(
  |[0,1][9,10]|)
