Moonshot Goal 6Realization of a fault-tolerant universal quantum computer that will revolutionize economy, industry, and security by 2050.

A fault-tolerant universal quantum computer will help tackle our complex social challenges.(PDF 677KB)

Outline

While it is said that the progress of conventional computers is reaching its limits, it is important to be able to respond to the explosion of information processing demands. If we want quantum computing to rapidly solve our numerous and complex social problems, we need a fault-tolerant universal quantum computer that can perform precise computation while correcting quantum errors. In order to realize such a fault-tolerant universal quantum computer we are conducting R&D into the relevant hardware, software, networks, and related quantum technologies.

【Message from PD】

In order to realize a fault-tolerant universal quantum computer, it is necessary to integrate a huge number of qubits, provide redundancy using quantum error correcting codes, and reduce the physically arising quantum error to below the fault-tolerant threshold. Therefore, we aim to develop a certain scale of quantum computers and demonstrate the effectiveness of quantum error correction.

Considering the possibility of massively integrated quantum computers through quantum communication, R&D projects will be implemented in three categories: ‘1) hardware’, ‘2) communication networks’, and ‘3) theory and software’. Specifically we would like R&D projects in each category to compete for feasibility, collaborate across categories, and conduct R&D to achieve the Moonshot Goal.
