IBM releases 'quantum computer roadmap', plans to finally reach the 1000 qubit mark in 2023


IBM Research

A quantum computer is a computer that can perform calculations that cannot be performed by ordinary computers using quantum mechanical phenomena. IBM , a leader in the field of quantum computers, has released a 'roadmap of quantum computer technology' and has set long-term goals such as 'to realize a quantum computer with performance exceeding 1000 qubits by 2023'. I have made it clear.

IBM, which has been conducting research on quantum computers since the mid-2000s, released a 5-qubit quantum computer on the cloud in May 2016, making it accessible from the outside. Since then, it has been improved at various levels of the system, and at the time of writing the article, it maintained as many as 24 stable quantum systems on IBM's cloud, and in September 2020, 65 qubits for some members. He also released a processor called ' IBM Quantum Hummingbird '.

The challenge in making a quantum computer larger is 'improvement of error rate', and even if the number of qubits is increased without improving the error rate, the performance will not improve. Therefore, IBM states that it is working to improve the performance of quantum computers by processing noise, improving wiring and components for reading qubit signals, and reducing signal processing latency.

According to the roadmap, IBM released the 127 qubit 'IBM Quantum Eagle' in 2021, the 433 qubit 'IBM Quantum Osprey' in 2022, and the 1121 qubit 'IBM Quantum Condor' in 2023. We plan to gradually increase the number of qubits. Among them, the 'IBM Quantum Condor' in 2023 is said to be an important turning point for quantum computers, and it is thought that this will allow us to explore the potential advantages of quantum computers.

The central mission of the roadmap released by IBM is 'designing a full-stack quantum computer that anyone can access via the cloud.' IBM plans to develop a quantum computer with a scale larger than the 'IBM Quantum Condor' in the future, but as the scale of the quantum computer grows, it seems that the dilution refrigerator used for cooling needs to be larger.

That's why IBM is developing a 10-foot-high, 6-foot-wide, 'Golden eye' diluting refrigerator. The 'Golden eye' is designed with the cooling of quantum computers of up to 1 million qubits in mind, and in the future, each 'Golden eye' containing a 1 million qubit quantum computer will be connected to each other to create a super It is also planned to create a parallel qubit computer.

Dario Gil, director of IBM Research, explains the future of quantum computers with examples from the semiconductor industry. In the early days of the semiconductor industry, a huge project team gathered to develop, but eventually a third-party vendor who played a part in the semiconductor industry appeared, and one company designed, developed, and developed everything necessary for semiconductors. It is no longer manufactured.

Gil believes that something similar could happen in the quantum computer industry in the future. Increasing complexity in the industry makes it harder for individual players to take on all of the development, and individual players in the ecosystem focus and contribute to their areas of expertise. IBM is investing in anticipation of such future movements.

And while IBM and many competitors are working on higher-performance hardware, hardware isn't the only thing that matters in quantum computers. Mr. Gil argued that the construction of software for quantum computers, that is, quantum algorithms and quantum circuits, is also necessary to improve the performance of quantum computers, and that software efforts should be started.
