slater_determinant_matrix
)
The input is an Nf×N matrix Q with orthonormal
rows. Such a matrix describes the Slater determinant
b†1⋯b†Nf|vac⟩,
where
b†j=N∑k=1Qjka†k.
The output is the description of a circuit which prepares this
Slater determinant, up to a global phase.
The starting state which the circuit should be applied to
is a Slater determinant (in the computational basis) with
the first Nf orbitals filled.

circuit_description
|
A list of operations describing the circuit. Each operation
is a tuple of elementary operations that can be performed in
parallel. Each elementary operation is a tuple of the form
(i,j,θ,φ), indicating a Givens rotation
of modes i and j by angles θ
and φ.
