Quantum computing has proven nice potential to rework particular algorithms and functions and is anticipated 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 comparable to restricted qubit coherence instances and a excessive likelihood of errors. As a result of complexity of quantum algorithms, the necessity for error correction turns into essential, introducing extra complexity. Whereas creating, testing, and debugging quantum algorithms, Quantum simulators play an essential position in offering a managed, and error-free atmosphere. It additionally enhances availability when there are restricted bodily assets.
Present works embrace varied 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 primary classes, unfastened and tight integration. Free integration has a extra versatile coupling between quantum and classical programs, whereas, tight integration makes use of quantum processing models (QPUs) into HPC nodes instantly, much like how graphics processing models (GPUs) are built-in into HPC compute nodes. This bond permits classical programs to deal with conventional duties whereas quantum processors remedy particular issues they’re greatest at fixing. Nonetheless, managing assets and optimizing efficiency poses challenges throughout these hybrid programs.
Researchers from Oak Ridge Nationwide Laboratory, Oak Ridge, TN, USA have proposed a Quantum framework (QFw) specializing in unfastened integration of quantum computing with HPC environments. This technique treats quantum computer systems as separate parts inside 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 programs. This framework supplies a unified answer for hybrid functions with the utmost advantages of HPC for quantum simulation, with a simple transition to actual quantum {hardware}. It additionally supplies a versatile infrastructure on the Frontier supercomputer, supporting varied quantum circuit-building instruments and simulators.
The proposed QFw is designed to allow researchers to totally leverage HPC assets for quantum computing whereas permitting a seamless transition between simulation backends and actual quantum {hardware}. With QFw, functions can individually allocate HPC assets for classical and quantum duties and use any circuit composition software program they like. The framework supplies a backend to transform native quantum circuit buildings into QASM 2.0, a standard quantum job format. The Quantum Process Supervisor (QTM) layer applies particular workflows comparable to circuit slicing and end result 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 working 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 impartial circuits concurrently and the advantages of good useful resource administration. Furthermore, a PennyLane software 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 flexibleness 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 package deal, making it simpler for researchers to deal with their duties. The QFw permits simulations on HPC programs to transcend regular limits and simply transition to bodily quantum {hardware}. Its versatility permits the mixing of various quantum platforms, with out infrastructure or software adjustments. Furthermore, QFw’s plugin structure supplies a standard API to combine new platforms simply.
