class ffsim.qiskit.DiagCoulombEvolutionSpinlessJW(norb, mat, time, *, label=None)

Bases: Gate

Spinless diagonal Coulomb evolution under the Jordan-Wigner transformation.

The spinless diagonal Coulomb evolution gate has the unitary

\[\exp\left(-i t \sum_{i, j} Z^{ij} n_i n_j / 2\right)\]

where \(n_i\) denotes the number operator on orbital \(i\) and \(Z\) is a real symmetric matrix.

Methods

inverse()

Inverse gate.
