Implementation of three-qubit Toffoli gate in a single step
Ai Min Chen, Sam Young Cho, Mun Dae Kim
Single-step implementations of multi-qubit gates are generally believed to provide a simpler design, a faster operation, and a lower decoherence. For coupled three qubits interacti…
Ground-state fidelity and tensor network states for quantum spin tubes
Ai-Min Chen, Qian-Qian Shi, Jin-Hua Liu +1
An efficient algorithm is developed for quantum spin tubes in the context of the tensor network representations. It allows to efficiently compute the ground-state fidelity per latt…
Ground-State Fidelity and Kosterlitz-Thouless Phase Transition for Spin 1/2 Heisenberg Chain with Next-to-the-Nearest-Neighbor Interaction
Hong-Lei Wang, Ai-Min Chen, Bo Li +1
The Kosterlitz-Thouless transition for the spin 1/2 Heisenberg chain with the next-to-the-nearest-neighbor interaction is investigated in the context of an infinite matrix product…
Is the Fano Antiresonance a Necessary Requirement for Circulating Currents in Mesoscopic Interferometers?
Yao Heng Su, Sam Young Cho, Ai Min Chen
Coherent quantum tunneling effects on quantum interference are investigated in electron transport through a mesoscopic interferometer. An evanescent wave tunneling through a potent…
Controllable conditional quantum oscillations and synchronization in superconducting flux qubits
Ai Min Chen, Sam Young Cho
Conditional quantum oscillations are investigated for quantum gate operations in superconducting flux qubits. We present an effective Hamiltonian which describes a conditional quan…
Entanglement and Berry Phase in Two Interacting Qubits
Ai Min Chen, Sam Young Cho, Taeseung Choi
Entanglement and Berry phase are investigated in two interacting qubit systems. The XXZ spin interaction model with a slowly rotating magnetic field is employed for the interaction…
