Topological Phase for Entangled Two-Qubit States
Topological Phase for Entangled Two-Qubit States
Entangled states play a crucial role in quantum physics, ranging from fundamental aspects to quantum information processing. We show here that entangled two-qubit states can also be used to characterize unambiguously the subtlety of the SO(3) rotation group topology. The well known two distinct families of path in this group …
