Experimental realization of a quantum spin pump.
We demonstrate the operation of a quantum spin pump based on cyclic radio-frequency excitation of a GaAs quantum dot, including the ability to pump pure spin without pumping charge. The device takes advantage of bidirectional mesoscopic fluctuations of pumped current, made spin dependent by the application of an in-plane Zeeman field. Spin currents are measured by placing the pump in a focusing...
متن کاملExperimental Realization of an NMR Quantum Switch
In this paper, we report an experimental realization of quantum switch using nuclear spins and magnetic resonant pulses. The nuclear spins of H and C in carbon13 labelled chloroform are used to carry the information, then nuclear magnetic resonance pulses are applied to perform either bypass or cross function to achieve the switching. Compared with a traditional space or time domain switch, thi...
متن کاملExperimental realization of a quantum game on a one-way quantum computer
We report the first demonstration of a quantum game on an all-optical one-way quantum computer. Following a recent theoretical proposal we implement a quantum version of Prisoner’s Dilemma, where the quantum circuit is realized by a 4-qubit box-cluster configuration and the player’s local strategies by measurements performed on the physical qubits of the cluster. This demonstration underlines t...

متن کاملMagnetic Shielding: A Demonstration and Experimental Realization
Action of electric and magnetic fields and their interaction effects are the basis of operation of every electrical and electronic instrument. But such action fields could also cause serious problems to the functioning of those instruments if they act on them unnecessarily, to the extreme, failure of the system may also occur. To avoid such unpleasant consequences arising out of unwanted electr...
