Abstract
If the states of spins in solids can be created, manipulated, and measured at
the single-quantum level, an entirely new form of information processing,
quantum computing and quantum communication, will be possible. We review our
proposed spin-quantum dot architecture for a quantum computer and review some
recent results on a deterministic source of entanglement generated by coupling
quantum dots. Addressing the feasibility of quantum communication with
entangled electrons we consider a scattering set-up with an entangler and beam
splitter where the current noise exhibits bunching behavior for electronic
singlet states and antibunching behavior for triplet states. We show that spin
currents can produce noise even in the absence of any charge currents.引用本文复制引用
