PauliEngine: High-Performant Symbolic Arithmetic for Quantum Operations
It provides a scalable backend for operator-based quantum software tools and simulations, addressing the need for fast classical manipulation of qubit operators in hybrid quantum-classical computation.
PauliEngine introduces a high-performance C++ framework for symbolic arithmetic of Pauli strings, achieving substantial runtime speedups over state-of-the-art implementations through binary symplectic representation and optimized bit-wise operations.
Quantum computation is inherently hybrid, and fast classical manipulation of qubit operators is necessary to ensure scalability in quantum software. We introduce PauliEngine, a high-performance C++ framework that provides efficient primitives for Pauli string multiplication, commutators, symbolic phase tracking, and structural transformations. Built on a binary symplectic representation and optimized bit-wise operations, PauliEngine supports both numerical and symbolic coefficients and is accessible through a Python interface. Runtime benchmarks demonstrate substantial speedups over state-of-the-art implementations. PauliEngine provides a scalable backend for operator-based quantum software tools and simulations.
