Tunable coupling between three qubits as a building block for a superconducting quantum computer
Tunable coupling between three qubits as a building block for a superconducting quantum computer
Large-scale quantum computers will consist of many interacting qubits. In this paper we expand the two flux qubit coupling scheme first devised by P. Plourde et al. [Phys. Rev. B 70, 140501 (2004)] and realized by T. Hime et al. [Science 314, 1427 (2006)] to a three-qubit, two-coupler scenario. We …
