Controllable anisotropic exchange coupling between spin qubits in quantum dots
Yun-Pil Shim, Sangchul Oh, Xuedong Hu +1
The exchange coupling between quantum dot spin qubits is isotropic, which restricts the types of quantum gates that can be formed. Here, we propose a method for controlling anisotr…
Effect of Randomness on Quantum Data Buses of Heisenberg Spin Chains
Sangchul Oh, Yun-Pil Shim, Jianjia Fei +2
A strongly coupled spin chain can mediate long-distance effective couplings or entanglement between remote qubits, and can be used as a quantum data bus. We study how the fidelity…
Macroscopic quantum state in a semiconductor device
Yun-Pil Shim, Anand Sharma, Chang-Yu Hsieh +1
We show how nanostructuring of a metallic gate on a field-effect transistor (FET) can lead to a macroscopic, robust and voltage controlled quantum state in the electron channel of…
