Hardware-Tailored Diagonalization Circuits
Published in npj Quantum Information, 2024
We present a theoretical framework for constructing hardware-tailored (HT) quantum circuits that efficiently diagonalize sets of commuting Pauli operators with minimal gate overhead. Unlike standard approaches that rely on tensor product bases or incur high SWAP costs, our method adapts circuit construction to hardware constraints, enabling more scalable implementations. We demonstrate an algorithm for grouping Hamiltonian terms into jointly HT-diagonalizable sets and show that our method reduces the number of required measurements compared to conventional strategies.
