Bounding the entanglement of a state from its spectrum
Jofre Abellanet-Vidal, Guillem Müller-Rigat, Albert Rico +1
We introduce a framework to upper bound the entanglement content of a bipartite quantum state from its spectrum alone. Using linear maps and their inverses, we derive rigorous cons…
Threshold entanglement sharing: quantum states with absolutely separable marginals
Albert Rico, Jofre Abellanet-Vidal, Naga Bhavya Teja Kothakonda +2
Motivated to understand how entanglement resources can be distributed in quantum networks, we introduce threshold entanglement (TE) states. These are multipartite quantum states wh…
Sufficient criteria for absolute separability in arbitrary dimensions via linear map inverses
Jofre Abellanet-Vidal, Guillem Müller-Rigat, Grzegorz Rajchel-MieldzioÄ +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…
