Testing the Kochen-Specker theorem with Josephson qubits
L. F. Wei, K. Maruyama, X. -B. Wang +2
We propose an experimental approach to {\it macro}scopically test the Kochen-Specker theorem (KST) with superconducting qubits. This theorem, which has been experimentally tested w…

Entanglement purification without controlled-NOT gates by using the natural dynamics of spin chains
Koji Maruyama, Franco Nori
We present a simple protocol to purify bipartite entanglement in spin-1/2 particles by utilizing only natural spin-spin interactions, i.e. those that can commonly be realized in re…
