The work is motivated by the need for conceptual tools for the development of quantum-communication systems that are usable by non-specialists in quantum physics while also correctly capturing at a useful abstraction the underlying quantum phenomena. Our approach involves defining a quantum abstract machine (QAM) whose operations correspond to well-known quantum circuits; these operations, however, are given direct abstract semantics in a style similar to that of Berry&#39;s and Boudol&#39;s Chemical Abstract Machine. This paper defines the QAM&#39;s semantics and shows via examples how it may be used to model and reason about existing quantum communication protocols.</p>1 aLi, Liyi1 aChang, Le1 aCleaveland, Rance1 aZhu, Mingwei1 aWu, Xiaodi  uhttps://arxiv.org/abs/2402.13469
