qfnn.qf_circ.n_lyr_circ module

class qfnn.qf_circ.n_lyr_circ.N_LYR_Circ(n_qubits, n_repeats=1)

Bases: qfnn.qf_circ.base.BaseCircuit

N_LYR_Circ is a class, which includes functions to build N-layer circuit(for batch normalization)

Parameters

• n_qubits – input qubits of each unit

• n_repeats – repeat times of each unit

add_norm_qubits(circuit)

add_out_qubits(circuit)

forward(circuit, input_qubits, norm_qubits, out_qubits, norm_flag, norm_para)

Function forward is to add the circuit of N-layer.

Parameters

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

• input_qubits – The register of input qubits

• norm_qubits – The register of qubits that do angle-encoding.

• out_qubits – The register of output qubits

• norm_flag – the direction of batch normalization.

• norm_para – the parameter of batch normalization encoded in the angle of qubits.
