Spin-Orbit-Induced Spin-Density Wave in a Quantum Wire
... SDWx phase ( ! ~ ). Since the 2pF component of the charge density describes backscattering (p ! p) of electrons by potential impurity, Eq. (8) implies irrelevancy of the impurity in the spin-density wave state. The reason for this is somewhat similar to that of backscattering suppression in the ...

When we want to send a qubit, a, we first interact a with b using a CNOT gate. We then measure the phase and the amplitude of a, send the two one-bit classica ...
