qfnn.qf_circ.v_lyr_circ module

class qfnn.qf_circ.v_lyr_circ.V_LYR_Circ(n_qubits, n_repeats)

Bases: qfnn.qf_circ.base.BaseCircuit

V_LYR_Circ is a class, which includes functions to build v-layer(vqc)

Parameters

  • n_qubits – input qubits of each unit

  • n_repeats – repeat times of each unit

add_input_qubits(circuit, name='vqc_input')

Function add_input_qubits is to add a group of qubits as input qubit .

Parameters

  • circuit – The circuit that you add the unit at the end

  • name – The name of the group

Returns

The register of qubits

Return type

qubits

forward(circuit, input_qubits, vqc_name, thetas)

Function forward is to add the circuit of VQC.

Parameters

  • circuit – The circuit that you add the unit at the end

  • input_qubits – The register of input qubits

  • vqc_name – The number of vqc architecture in the paper.

  • thetas – A list of angles to be encoded into of vqc architecture in the paper.

  • aux – aux qubits
