Title:
ELECTRON-TRAPPING DEVICE, QUANTUM COMPUTER, METHOD FOR MANUFACTURING FLIP-CHIP STRUCTURE, AND ELECTRON-TRAPPING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/047956
Kind Code:
A1
Abstract:
This electron-trapping device 1 comprises a low-temperature device 1, a superconducting circuit 10, and a hot bath 60. The superconducting circuit 10 and the hot bath 60 are arranged in the low-temperature device 40. This makes it possible for the superconducting circuit 10 to operate and keeps the hot bath 60 at a given low temperature (e.g., about 20 mK). The superconducting circuit 10 is provided with a cooling resonator 20, a microwave resonator 22, and an electron-trapping region 50. The superconducting circuit 10 has a microstructure in which electrodes that face each other are disposed at positions having line symmetry about a center line passing through the electron-trapping region and are surrounded by a superconductor so that the electron-trapping region 50 is configured from a plurality of facing electrodes.
