This paper introduces the autonomous Quantum Processing Unit (aQPU), a theoretical framework modeling quantum computation as self-contained thermal machines rather than relying on external classical control. By integrating internal timekeeping and memory, it establishes new bounds linking thermodynamic costs to computational speed, complexity, and fidelity for fully isolated systems. This work advances fundamental understanding of physical limits in quantum information processing without proposing immediate hardware implementations or consumer applications.
Autonomous Quantum Processing Unit: An Autonomous Thermal Computing Machine & its Physical Limitations
arXiv:2402.00111v3 Announce Type: replace Abstract: Computation is an input-output process, where a program encoding a problem to be solved is inserted into a machine that outputs a solution. Quantum computation conventionally relies on classical, external control outside the quantum computer to execute a program, obscuring computational and thermodynamic resources required. To understand the fundamental limits of computation, however, it is pivotal to work with a fully self-contained description of a quantum computation, modeling the resources on the same footing as the computation itself. By developing a framework that we dub the autonomous Quantum Processing Unit (aQPU) we model quantum computation in the framework of autonomous thermal machines. Consisting of an internal quantum timekeeping mechanism, instruction register and memory system the aQPU allows investigating relationships between thermodynamic cost, complexity, speed and fidelity of a desired quantum computation.
