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.

Microsoft is pursuing topological qubits with its Majorana hardware program while offering Azure Quantum as a cloud aggregator of partner hardware. The topological bet is high-risk and high-reward: if the underlying physics holds up, the resulting qubits would be intrinsically more stable than any competing approach. Software side: the Q# language and Azure Quantum job orchestration.
