The research group led by Chen Jianxin at the Quantum Software Research Center within the Department of Computer Science at Tsinghua University, in partnership with Yan Fei's team at the Beijing Academy of Quantum Information Sciences, has attained a significant milestone in quantum computer architecture. They have developed AshN, the first instruction set architecture that enables direct programming of arbitrary two-qubit quantum gates. This groundbreaking achievement has been featured in Nature Physics. AshN employs a unified control scheme to comprehensively encompass all equivalence classes of two-qubit unitary matrices, thereby substantially reducing the number of gate operations and minimizing error accumulation. This innovation offers a fresh perspective and technical trajectory for advancements in the realm of quantum computing.
