* Defines the inverse of the global phase The inverse of UCGate is defined by simply inverting the existing decomposition, but the inverse of the global phase was missing. * Tests the UCGate.inverse() function * Lint * Seed for building the matrices * Replace `unitary_simulator` by using `qiskit.quantum_info.Operator`. Co-authored-by: Julien Gacon <gaconju@gmail.com> * Import `Operator` class * Release notes * Lint * Test the phase of isometry decomposition * Removes the `prelude` from the release notes file * Replaces `matrix_equal` with `np.allclose` Co-authored-by: Julien Gacon <gaconju@gmail.com> (cherry picked from commit 82c85d8)
