QUANTUM ENTANGLEMENT GENERATION DEVICE, QUANTUM ENTANGLEMENT GENERATION METHOD, AND QUANTUM COMPUTER
Document Type and Number:
WIPO Patent Application WO/2022/190684
Kind Code:
A1
Abstract:
A quantum entanglement generation device 10 comprises, when n is an integer of 2 or more, two superconducting quantum bit elements 20a and 20b each having three electrodes, a coupled resonator 30 disposed between the adjacent superconducting quantum bit elements 20a and 20b, and waveguides 50a and 50b capacitive-coupled to the superconducting quantum bit elements 20a and 20b, respectively. The coupled resonator 30 generates quantum entanglement between the adjacent superconducting quantum bit elements 20a and 20b by applying a two-qubit gate between the adjacent superconducting quantum bit elements 20a and 20b. The superconducting quantum bit elements 20a and 20b generate a two-dimensional cluster state by emitting the quantum entanglement as propagating microwave photons to the waveguides 50a and 50b.
