UCPauliRotGate

class UCPauliRotGate(angle_list, rot_axis)

Bases: Gate

Uniformly controlled rotations (also called multiplexed rotations). The decomposition is based on ‚Synthesis of Quantum Logic Circuits‘ by Shende et al. (https://arxiv.org/pdf/quant-ph/0406176.pdf)

Input: angle_list = list of (real) rotation angles [a_0,…,a_{2^k-1}]. Must have at least one entry.

rot_axis = rotation axis for the single qubit rotations

(currently, ‚X‘, ‚Y‘ and ‚Z‘ are supported)

Create a new gate.

Parameter

• name – The Qobj name of the gate.

• num_qubits – The number of qubits the gate acts on.

• params – A list of parameters.

• label – An optional label for the gate.

Methods
