    IBM launches its most powerful quantum computer yet

    IBM said it has launched its most powerful quantum computer to date called the Osprey, a 433-qubit machine.

    IBM said it has launched its most powerful quantum computer to date called the Osprey, a 433-qubit machine that has three times the number of qubits than its Eagle machine announced last year.

    The number of qubits, or quantum bits, are an indication of the power of the quantum computer, which uses quantum mechanics — although different quantum computer companies make different claims about the power of their qubits which can be created many different ways.

    Quantum computers are one day expected to speed up certain calculations millions of times faster than the fastest supercomputers today.

    We have been designing and engineering the whole architecture for quantum computing based on modularity

    Dario Gil, IBM’s director of research, said IBM is still on track to launch a computer with over a thousand qubits but for further scaling was working on a new approach.

    “As we push the limits of the size of the Osprey chip that we’re announcing, if you look at it, it’s really big already. Next year, a thousand is going to be very big,” he said. “So after that, we have been designing and engineering the whole architecture for quantum computing based on modularity.”

    IBM is calling the modular system Quantum System Two.

    “Quantum System Two is the first truly modular quantum computing system so that you can continue to scale to larger and larger systems over time,” Gil said in an interview ahead of the IBM Quantum Summit this week. “Modularity means the chips themselves are going to have to be interconnected to one another.”

    Next year

    IBM said it is targeting for this system to be online by end of next year and it would be the building blocks for “quantum-centric supercomputing” by connecting multiple Quantum System Twos. IBM said it could build a system with up to 16 632 qubits by linking three of these systems.

    IBM has over 20 quantum computers around the world, and customers can access them through the cloud.  — Jane Lanhee Lee, (c) 2022 Reuters
