Quantum computing has proven nice potential to rework particular algorithms and purposes and is predicted to work alongside conventional Excessive-Efficiency Computing (HPC) environments. Furthermore, Noisy Intermediate-Scale Quantum (NISQ) units have emerged as highly effective computational platforms, however they face challenges akin to restricted qubit coherence occasions and a excessive likelihood of errors. As a result of complexity of quantum algorithms, the necessity for error correction turns into vital, introducing further complexity. Whereas growing, testing, and debugging quantum algorithms, Quantum simulators play an necessary function in offering a managed, and error-free atmosphere. It additionally enhances availability when there are restricted bodily sources.
Present works embrace numerous approaches to combine quantum computing into HPC environments. This integration method makes use of the ability of quantum algorithms whereas sustaining the reliability and flexibility of conventional computing. It’s divided into two essential classes, free and tight integration. Free integration has a extra versatile coupling between quantum and classical techniques, whereas, tight integration makes use of quantum processing models (QPUs) into HPC nodes instantly, just like how graphics processing models (GPUs) are built-in into HPC compute nodes. This bond permits classical techniques to deal with conventional duties whereas quantum processors clear up particular issues they’re greatest at fixing. Nevertheless, managing sources and optimizing efficiency poses challenges throughout these hybrid techniques.
Researchers from Oak Ridge Nationwide Laboratory, Oak Ridge, TN, USA have proposed a Quantum framework (QFw) specializing in free integration of quantum computing with HPC environments. This methodology treats quantum computer systems as separate parts throughout the bigger HPC system and focuses on on-premises integration. On this case, a quantum machine is related to the HPC middle utilizing high-bandwidth interconnects and a distributed file system, connecting it with classical HPC techniques. This framework gives a unified answer for hybrid purposes with the utmost advantages of HPC for quantum simulation, with a straightforward transition to actual quantum {hardware}. It additionally gives a versatile infrastructure on the Frontier supercomputer, supporting numerous quantum circuit-building instruments and simulators.
The proposed QFw is designed to allow researchers to totally leverage HPC sources for quantum computing whereas permitting a seamless transition between simulation backends and actual quantum {hardware}. With QFw, purposes can individually allocate HPC sources for classical and quantum duties and use any circuit composition software program they like. The framework gives a backend to transform native quantum circuit constructions into QASM 2.0, a standard quantum process format. The Quantum Process Supervisor (QTM) layer applies particular workflows akin to circuit reducing and outcome aggregation. The Quantum Platform Supervisor (QPM) handles communication with the platform, executing quantum duties by means of platform-specific operations.
The QFw is evaluated utilizing completely different frontends like Qiskit and PennyLane, and backends like TNQVM and NWQ-Sim. The SupermarQ benchmark is used to generate a 20-qubit GHZ circuit, and measure efficiency. The outcomes obtained on evaluating QFw present the effectivity in operating a number of simulations collectively, and finishing 8 simulations in 66.97 seconds, in comparison with 52.47 seconds for a single simulation. This highlights the potential for saving time when simulating unbiased circuits concurrently and the advantages of sensible useful resource administration. Furthermore, a PennyLane utility is efficiently built-in, demonstrating the QFw’s flexibility in combining completely different frontends and backends.
In conclusion, researchers from Oak Ridge Nationwide Laboratory, have launched a Quantum framework (QFw) providing researchers the pliability to advance quantum analysis on the Frontier supercomputer with none technical limitations. It permits customers to make the most of any frontend circuit-building software program with any backend simulation bundle, making it simpler for researchers to deal with their duties. The QFw permits simulations on HPC techniques to transcend regular limits and simply transition to bodily quantum {hardware}. Its versatility permits the mixing of various quantum platforms, with out infrastructure or utility adjustments. Furthermore, QFw’s plugin structure gives a standard API to combine new platforms simply.
