Sufficient criteria for absolute separability in arbitrary dimensions via linear map inverses
Jofre Abellanet-Vidal, Guillem Müller-Rigat, Grzegorz Rajchel-Mieldzioć +1
Quantum states that remain separable (i.e., not entangled) under any global unitary transformation are known as absolutely separable and form a convex set. Despite extensive effort…
