Learning quantum disentanglement scheduling from reduced states via modular hybrid policies
Y. -X. Xiao, J. -Z. Han, Z. Zheng +4
Quantum control with restricted state access is central to near-term quantum devices, where full wave-function information is unavailable. We study this problem through multiqubit…
Scalable high-fidelity and near-deterministic preparation of large photon-number states
Mo Xiong, Jize Han, Chuanzhen Cao +3
The scalable preparation of large photon-number (Fock) states is a long-standing frontier in quantum science, with direct implications for quantum metrology and bosonic quantum inf…
Enhancing Dynamic Range of Sub-Quantum-Limit Measurements via Quantum Deamplification
Qi Liu, Ming Xue, Matthew Radzihovsky +4
Balancing high sensitivity with a broad dynamic range is a fundamental challenge in measurement science, as improving one often compromises the other. While traditional quantum met…
Improving adiabatic quantum factorization via chopped random-basis optimization
Tianlai Yang, Mo Xiong, Ming Xue +2
Integer factorization remains a significant challenge for classical computers and is fundamental to the security of RSA encryption. Adiabatic quantum algorithms present a promising…
Efficient generation of multiqubit entanglement states using rapid adiabatic passage
Shijie Xu, Xinwei Li, Xiangliang Li +2
We propose the implementation of a rapid adiabatic passage (RAP) scheme to generate entanglement in Rydberg atom-array systems. This method transforms a product state in a multi-qu…
High-fidelity and robust controlled-Z gates implemented with Rydberg atoms via echoing rapid adiabatic passage
Ming Xue, Shijie Xu, Xinwei Li +1
High-fidelity and robust quantum gates are essential for quantum information processing, where neutral Rydberg atoms trapped in optical tweezer arrays serving as a versatile platfo…
