Probing Quantum Phase Transitions on a Spin Chain with a Double Quantum Dot
Yun-Pil Shim, Sangchul Oh, Jianjia Fei +2
Quantum phase transitions (QPTs) in qubit systems are known to produce singularities in the entanglement, which could in turn be used to probe the QPT. Current proposals to measure…
Mediated gates between spin qubits
Jianjia Fei, Dong Zhou, Yun-Pil Shim +3
In a typical quantum circuit, nonlocal quantum gates are applied to nonproximal qubits. If the underlying physical interactions are short-range (e.g., exchange interactions between…
Resonant Adiabatic Passage with Three Qubits
Sangchul Oh, Yun-Pil Shim, Jianjia Fei +2
We investigate the non-adiabatic implementation of an adiabatic quantum teleportation protocol, finding that perfect fidelity can be achieved through resonance. We clarify the phys…
