As an example, IBM holds the lead in quantum scaling with the 433-qubit Osprey processor introduced in 2022 and is slated to introduce the 1,121-qubit Condor processor later this year.
Another reason is the continued advancements being made in quantum computing is improvements in quantum chips, control logic, systems, and software. These advancements are especially true of the development tools for error mitigation, suppression, and correction. As an example, IBM holds the lead in quantum scaling with the 433-qubit Osprey processor introduced in 2022 and is slated to introduce the 1,121-qubit Condor processor later this year. If you consider IBM’s quantum processor roadmap, the number of qubits will increase by approximately 2-3x every year. IBM is also networking quantum computers together to further increase the qubit capacity. IBM has stated that it has a goal of 100,000 qubit systems by 2033. Industry and academia are already working on practical applications with current quantum computers. This development will accelerate as qubit capacity increases in the latter half of this decade.
