Arqit's QuantumCloud offers a network-agnostic quantum-safe key distribution layer targeted at governments, telecoms, and critical infrastructure. Approach sidesteps the fiber/free-space distance limits of traditional QKD by using a cloud-brokered symmetric key protocol. Revenue is still nascent (government pilot contracts); differentiation from NIST PQC algorithms is contested by some cryptographers. Risk: extremely small revenue base, ongoing cash burn, and debate over whether QuantumCloud constitutes true QKD or a classical symmetric-key wrapper.
