Quantum computing through electron propagation in the edge states of quantum spin Hall systems
Wei Chen, Zheng-Yuan Xue, Z. D. Wang +2
We propose to implement quantum computing based on electronic spin qubits by controlling the propagation of the electron wave packets through the helical edge states of quantum spi…
Inductance Due to Spin Current
Wei Chen
The inductance of spintronic devices that transport charge neutral spin currents is discussed. It is known that in a media that contains charge neutral spins, a time-varying electr…
All-electrically reading out and initializing topological qubits with quantum dots
Wei Chen, Zheng-Yuan Xue, Z. D. Wang +2
We analyze the reading and initialization of a topological qubit encoded by Majorana fermions in one-dimensional semiconducting nanowires, weakly coupled to a single level quantum…
Probing spin entanglement by gate-voltage-controlled interference of current correlation in quantum spin Hall insulators
Wei Chen, Z. D. Wang, R. Shen +1
We propose an entanglement detector composed of two quantum spin Hall insulators and a side gate deposited on one of the edge channels. For an ac gate voltage, the differential noi…
Flux Quantization Due to Monopole and Dipole Currents
Wei Chen, Peter Horsch, Dirk Manske
By discussing field-induced quantum interference effects due to monopole moments and those due to dipole moments on equal footing, their similarities and differences are clarified.…
