embed_clifford(s, p, qubit_inds, n)#

Embeds the (s,p) Clifford symplectic representation into a larger symplectic representation.

The action of (s,p) takes place on the qubit indices specified by qubit_inds.

Parameters:

  • s (numpy array) – The symplectic matrix over the integers mod 2 representing the Clifford

  • p (numpy array) – The ‘phase vector’ over the integers mod 4 representing the Clifford

  • qubit_inds (list) – A list or array of integers specifying which qubits s and p act on.

  • n (int) – The total number of qubits

Returns:

  • s (numpy array) – The symplectic matrix over the integers mod 2 representing the embedded Clifford

  • p (numpy array) – The ‘phase vector’ over the integers mod 4 representing the embedded Clifford
