Efficient one-step generation of large cluster states with solid-state circuits
J. Q. You, Xiang-bin Wang, Tetsufumi Tanamoto +1
Highly entangled states called cluster states are a universal resource for measurement-based quantum computing (QC). Here we propose an efficient method for producing large cluster…
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…
Measurement-based quantum computation with superconducting charge qubits
Xiang-bin Wang, J. Q. You, Franco Nori
We present a robust method, based only on measurements, to produce superconducting cluster states. The measurement of the current of a few parallel Josephson-junction qubits realiz…
Superconducting Circuits and Quantum Information
J. Q. You, Franco Nori
Superconducting circuits can behave like atoms making transitions between two levels. Such circuits can test quantum mechanics at macroscopic scales and be used to conduct atomic-p…
