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…

Even-Odd Effects of Heisenberg Chains on Long-range Interaction and Entanglement
Sangchul Oh, Mark Friesen, Xuedong Hu
A strongly coupled Heisenberg chain provides an important channel for quantum communication through its many-body ground state. Yet, the nature of the effective interactions and th…
