Quantum thesis
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.

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.
