IBM says its future is in quantum-centered supercomputing and plans to have the 4,000 qubit 'System Two' online by 2025, stitching three together for a 16,000 qubit machine soon after. It uses chip to chip communication to allow them to work in concert for more rapid scale-up.

Jay Gambetta, IBM Fellow and vice president of IBM Quantum said 2023 is a major inflection point for quantum computing, the starting point when the quantum-centric supercomputer is first realised and scaling is enabled. He said that it does so by “combining quantum communication and computation to increase computational capacity”.
British startup Universal Quantum is taking a similar approach, developing multi-chip quantum computers for more rapid scaleup.
But it is still some time before we reach any real supremacy as a study by the University of Sussex found we'd need 13 million qubits to crack 256 bit encryption in a day.
