is_hermitian

Method of Operator.

is_hermitian() -> bool​

Returns true if the operator is Hermitian (self-adjoint). Conservative method: May return false for operators that are actually Hermitian. When true is returned, it is guaranteed to be correct.

Returns​

true if the operator is provably Hermitian, false otherwise (including cases where it may be Hermitian but cannot be verified).

Example​

var h1 = is_hermitian(X(0) + Z(0))   // true (provably Hermitian)
var h2 = X(0).is_hermitian()         // true
var h3 = is_hermitian(Sgate(0))      // false (provably not Hermitian)
