New Blueprint Lets Quantum Programs Run on Any Hardware Without Rewriting
Researchers have created a middle layer that lets quantum applications switch between different quantum computers — from gate-based systems to annealers — by changing only a configuration file, not the code itself. The approach, borrowed from decades of high-performance computing practices, could dramatically reduce the cost and complexity of deploying quantum solutions across competing hardware platforms.
Originaltitel: An HPC-Inspired Blueprint for a Technology-Agnostic Quantum Middle Layer
<p>We present a blueprint for a quantum middle layer that supports applications across various quantum technologies. Inspired by concepts and abstractions from HPC libraries and middleware, our design is backend-neutral and context-aware. A program only needs to specify its intent once as typed data and operator descriptors. It declares what the quantum registers mean and which logical transformations are required, without committing to gates, pulses, continuous-variable routines, or anneal backend. Such execution details are carried separately in a context descriptor and can change per backend without modifying the intent artifacts. We develop a proof of concept implementation that uses JSON files for the descriptors and two backends: a gate-model path realized with IBM Qiskit Aer simulator and an annealing path realized with D-Wave Ocean’s simulated annealer. On a Max-Cut problem instance, the same typed problem runs on both backends by varying only the operator formulation (Quantum Approximated Optimization Algorithm formulation vs. Ising Hamiltonian formulation) and the context. The proposed middle layer concepts are characterized by portability, composability, and its minimal core can evolve with hardware capabilities.</p>
