Title:
QUANTUM COMPUTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/170392
Kind Code:
A1
Abstract:
Provided is a quantum computing device having a reduced number of electrodes. The quantum computing device is provided with: a plurality of superconducting lines which are arranged so as to form at least two unit lattices in plan view, and which each constitute a quantum bit by an electromagnetic state; a plurality of first couplers which are provided at intersecting portions of the plurality of superconducting lines, and which cause two quantum bits to interact with each other; a plurality of second couplers which cause two quantum bits included in different unit lattices among the at least two unit lattices to interact with each other; and a plurality of electrodes which are electrically connected to any of the plurality of superconducting lines, the plurality of first couplers, and the plurality of second couplers. At least some of the plurality of second couplers are not electrically connected to any of the plurality of electrodes.
