IBM announces its quantum supercomputer by 2025

IBM has updated its roadmap, which describes all its future quantum projects. A computer expert reminded on Tuesday, May 10, that he wants to be at the forefront of quantum technology. After offering the most powerful quantum processor in late 2021, it now aims to develop a quantum supercomputer by 2025. This device with a computing power of 4000 qubits will expand all the possibilities of using quanta.

The project is in several stages

IBM’s latest achievement in quantum computing is the 127-quatt Eagle processor. Combined with IBM’s open source Qiskit development kit in 2021, this component already offers developers the ability to perform advanced quantum computing with basic knowledge. This makes it possible, for example, to model molecules with unsurpassed accuracy, which is very useful for drug development. The computer giant wants to go even further by launching its supercomputer to expand its field of possibilities.

This quantum supercomputer, which would have a computing power of 4,000 qubits, will appear by 2025. The process of its design will be carried out in several stages. IBM’s first goal is to develop its 433-cubic-meter Osprey chip, which will be released in 2022. This component lays the first bricks in the design of another even more powerful chip: Condor. It has a capacity of 1,000 qubits and will appear in 2023.

This desire for power is an intermediate step in creating a quantum supercomputer. These increasingly powerful processors will allow IBM to develop longer quantum circuits to increase computer processing speeds. This rate, measured in CLOPS (circuit-level operations per second), is expected to increase from 2,900 to 10,000 operations per second by 2025. Introduced by IBM in 2021, this unit measures the speed at which quantum processors are able to activate chips. in the quantum circuit.

Application in many areas

To accomplish this feat, IBM plans to combine several quantum processors into a circuit, both in parallel and in series. The purpose of this step is to minimize the risk of error and better coordinate the processors between them. These are two prerequisites for the work of tomorrow’s quantum computers.

From this point on, the process of designing a quantum supercomputer will take on a more specific form. IBM will develop chip disconnectors that connect several chips together to create a larger processor. Then these new processors, in turn, will be connected to others by quantum communication. Thus, they will train a larger and larger processor until they get a supercomputer at 4,000 qubits.

The applications made possible by such a machine go beyond anything that can be done today with a conventional supercomputer. “ By 2025, developers will be able to explore quantum use in machine learning, optimization, finance, science, and more. explains Jay Gambetta, an IBM researcher. Quantum computing must play an important role in tomorrow’s challenges. It could help in the development of batteries or medicines, but it also has applications that have not yet been found.
