Maximally Entangled Mixed States: Do They Exist?

Explore a seminar on the existence of maximally entangled mixed states in quantum information theory. Delve into the concept of maximally entangled states and their significance as the most useful states for entanglement-based applications. Examine the practical challenges of dealing with mixed states due to noise and investigate whether a notion of maximally entangled mixed states is possible under constrained mixedness. Learn about the long-standing question of maximally entangled states with fixed spectra and their preparation through Hamiltonian dynamics. Discover the solution to this problem as presented by Julio de Vicente from Universidad Carlos III de Madrid in this comprehensive 1-hour and 12-minute talk from the Quantum Information and Quantum Computing Seminars at Centrum Fizyki Teoretycznej PAN.
