Quantum Computing Era Dawns

What happened

Quantum computing's global market expanded to between $1.8 billion and $3.5 billion in 2025, with projections indicating a rise to $20.2 billion by 2030, supported by over $2 billion in venture capital funding in 2024. Significant progress in quantum error correction, exemplified by Google's 105-qubit Willow chip demonstrating exponential error reduction and IonQ achieving 99.99% accuracy on core gate actions, has reduced qubit requirements. New hardware includes Fujitsu and RIKEN's 256-qubit superconducting computer, with a 1,000-qubit machine planned by 2026, IBM's 1,386-qubit Kookaburra processor due in 2025, and Quantinuum's Helios system. These systems are now applied in traffic optimisation, telecom performance, and medical device simulation.

Why it matters

The accelerated commercialisation and increasing capabilities of quantum computing introduce an operational constraint by significantly increasing the complexity of future computational environments. This raises due diligence requirements for IT security and strategic planning teams to assess emerging cryptographic vulnerabilities and integrate novel processing capabilities. Procurement and R&D departments face an increased burden in evaluating quantum-ready infrastructure and talent, increasing exposure to new technological dependencies and potential skill gaps within the organisation.
