Quantum thesis
Arqit sells symmetric-key encryption software designed to be resilient against future quantum attacks. It is not a quantum computer company; it is a post-quantum cryptography company whose product addresses the security threat that scalable quantum computing would create. Read Arqit as a security thesis adjacent to the quantum trade, not as a bet on quantum hardware itself.

IBM runs the most mature commercial quantum program of any public company. IBM Quantum operates a fleet of superconducting processors over the cloud, publishes a detailed hardware roadmap, and ships Qiskit, the most widely used open-source quantum software stack. Quantum is a tiny share of IBM revenue, but no other diversified bet has more direct quantum exposure or a longer track record.
