Low-decoherence flux qubit
J. Q. You, Xuedong Hu, S. Ashhab +1
A flux qubit can have a relatively long decoherence time at the degeneracy point, but away from this point the decoherence time is greatly reduced by dephasing. This limits the pra…
Equation-of-motion treatment of hyperfine interaction in a quantum dot
Changxue Deng, Xuedong Hu
Isolated electron spins in semiconductor nanostructures are promising qubit candidates for a solid state quantum computer, There have seen truly impressive experimental progresses…
Producing cluster states in charge qubits and flux qubits
Tetsufumi Tanamoto, Yu-xi Liu, Shinobu Fujita +2
We propose a method to efficiently generate cluster states in charge qubits, both semiconducting and superconducting, as well as flux qubits. We show that highly-entangled cluster…
Quantum electromechanics: Quantum tunneling near resonance and qubits from buckling nanobars
Sergey Savel'ev, Xuedong Hu, A. Kasumov +1
Analyzing recent experimental results, we find similar behaviors and a deep analogy between three-junction superconducting qubits and suspended carbon nanotubes. When these differe…
