Multipartite entanglement: combinatorics, topology, and ... astronomy Speaker(s): Karol Zyczkowski
Abstract:
A brief introduction to entanglement of multipartite pure quantum states will be given. As the Bell states are known to be maximally entangled among all twoqubit quantum states, a natural question arises: What is the most entangled state for the quantum system consisting of N subsystems with d levels each? The answer depends on the entanglement measure selected, but already for fourqubit system, there is no state which displays maximal entanglement with respect to all three possible splittings of the systems into two pairs of qubits.
