CliffordUtils.v_gates

CliffordUtils.v_gates(gatelist, q, v)

Adds an axis-swap gate V or W on qubit q to a given list of gates.

The V gate is defined as: V=HSHS = [[0,1],[1,1]]. It makes a rotation of the paulis: Z->X->Y->Z V is of order 3, and two V-gates is a W-gate, so: W=VV and WV=I.

Parameters

• gatelist (list) – a list of gates.

• q (int) – an index of the qubit.

• v (int) –

  an integer indicating the gate:

  • 1 - for V gate.

  • 2 - for W gate.

Returns

A list of gates, after appending a gate V or W on qubit q.

Return type
