Services QaaS

Quantum as a Service (QaaS) is a cloud service model that provi­des remote, on‑demand access to quantum compu­ting resources—such as real quantum proces­sors, emula­tors, and develo­p­ment tools—over the inter­net. It is part of the broader quantum service enginee­ring, i.e. the appli­ca­tion of service‑oriented enginee­ring princi­ples, methods, and tools to the design, imple­men­ta­tion, and deploy­ment of quantum compu­ting capabi­li­ties while hiding hardware and compi­la­tion layers. QaaS lets develo­pers run quantum algorithms and build quantum‑enabled appli­ca­ti­ons without owning or opera­ting any quantum hardware themsel­ves. This supports hybrid quantum‑classical appli­ca­ti­ons, where classi­cal code offloads speci­fic optimiza­tion, simula­tion, or crypto­gra­phic tasks to quantum backends. Research propo­ses quantum service‑oriented archi­tec­tures where quantum capabi­li­ties are encap­su­la­ted as micro­ser­vices that can be independently deployed, scaled, and versio­ned, similar to classi­cal micro­ser­vice ecosystems.
