Researchers at Intel Labs developed an LLVM-based C++ compiler toolchain designed for variational hybrid quantum-classical algorithms, which supports dynamic parameter updates at runtime. This approach allows a single compilation for all iterative runs of such algorithms, effectively reducing execution latency and enhancing the efficiency of quantum-classical computations.
Key insights
- The "compile once, run many times" paradigm for variational algorithms significantly reduces overall execution latency by avoiding recompilation in each iteration.
- Integrating quantum and classical logic within a single LLVM-based C++ toolchain enables a unified programming model and leverages mature classical compiler optimizations.
- The introduction of a Quantum Runtime (QRT) library capable of dynamically updating parameterized quantum instructions at execution time is crucial for efficient execution of iterative hybrid algorithms.
