Unifying Qubit Routing Across Diverse Quantum ISAs via Canonical Representation
Zhaohui Yang, Kai Zhang, Xinyang Tian +6
Qubit mapping/routing is a critical stage in compilation for both near-term and fault-tolerant quantum computers, yet existing scalable methods typically impose several times the r…
Room-Temperature entangled quantum processor on integrated semiconductor photonics platform
Haibo Hu, Yu Zhou, Ailun Yi +9
The rise of the 4H-silicon-carbide-on-insulator (SiCOI) platform marks a promising pathway towards the realization of monolithic quantum photonic networks. However, the challenge o…
GSQAS: Graph Self-supervised Quantum Architecture Search
Zhimin He, Maijie Deng, Shenggen Zheng +2
Quantum Architecture Search (QAS) is a promising approach to designing quantum circuits for variational quantum algorithms (VQAs). However, existing QAS algorithms require to evalu…
Experimental Examination of Entanglement Estimates
Songbo Xie, Yuan-Yuan Zhao, Chao Zhang +4
Recently a proper genuine multipartite entanglement (GME) measure has been found for three-qubit pure states [see Xie and Eberly, Phys. Rev. Lett. 127, 040403 (2021)], but capturin…
Complementarity between Success Probability and Coherence in Grover Search Algorithm
Minghua Pan, Haozhen Situ, Shenggen Zheng
Coherence plays a very important role in Grover search algorithm (GSA). In this paper, we define the normalization coherence N(C), where C is a coherence measurement. In virtue of…
Quantum Architecture Search with Meta-learning
Zhimin He, Chuangtao Chen, Lvzhou Li +2
Variational quantum algorithms (VQAs) have been successfully applied to quantum approximate optimization algorithms, variational quantum compiling and quantum machine learning mode…
