In a blog post, Jay Gambetta, vice president of IBM Quantum, said the company's roadmap is part of a larger mission "to design a full-stack quantum computer deployed via the cloud that anyone around the world can program."
Indeed, cloud computing is the way most quantum resources will be consumed given the size and refrigeration required. The road to 1,000-qubits will include the following:
IBM will debut its 127-qubit IBM Quantum Eagle processor next year.
Quantum Eagle will include upgrades such as through-silicon vias and multi-level wiring. The quantum processor will also be able to reduce crosstalk errors.
In 2022, IBM plans to release a 433-qubit IBM Quantum Osprey system, which will be more efficient and be able to scale with better cryogenic infrastructure and controls.
