IBM is set to follow its roadmap for achieving large-scale, practical quantum computing by announcing plans to build 4000+ qubit quantum computers by the end of 2025.
The company aims to build a modular architecture that will enable more qubits in quantum computers. Along with that, IBM is working on a software orchestration layer to distribute the workloads across classical and quantum resources.
IBM announced its quantum roadmap in the year 2020, and since then, the company has delivered on its targets on predetermined timelines. The company is set to launch IBM Osprey, a 433-qubit processor, later this year, while IBM Condor, a first-ever universal quantum processor with 1000+ cubits, will be available by 2023.

Moreover, IBM is succeeding in achieving its set goals for 2023 for developing Qiskit Runtime and other workflows built in the cloud to bring a serverless approach to the core quantum software stack, giving developers advanced flexibility and simplicity.
The serverless approach will be a pioneering step in achieving the effective and efficient distribution of problems across quantum and classical systems, creating the fabric of quantum-centric supercomputing.
According to IBM CEO Arvind Krishna, there are a few hurdles that might hinder the plans to build the 4000 qubit system. Scaling the quantum computer systems, communicating amongst them, and getting the software to work and scale from a cloud into the computers are some of the problems Krishna mentioned.
