check_valid_clifford(s, p)#

Checks if a symplectic matrix - phase vector pair (s,p) is the symplectic representation of a Clifford.

This uses the formulas derived in Hostens and De Moor PRA 71, 042315 (2005).

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

Returns:

True if (s,p) is the symplectic representation of some Clifford.

Return type:

bool
