SC Online is carrying a story about an interesting result from the front line of quantum computing research
Scientists used light to establish what’s called “entanglement” between two atoms, which were trapped a meter apart in separate enclosures (think of entangling like controlling the outcome of one coin flip with the outcome of a separate coin flip).
…”The separation of the qubits in our entangled state is the most important feature,” Moehring said. “Localized entanglement has been performed in ion trap qubits in the past, but if one desires to build a scalable quantum computer network (or a quantum internet), the creation of entanglement schemes between remotely entangled qubit memories is necessary.”
The experiment is detailed in the Sep 6 edition of Nature.
