Phase diagram of a dual-species Rydberg atom ladder
Lei-Yi-Nan Liu, Shi-Rong Peng, Ze-Yuan Huang +4
Dual-species Rydberg atom arrays extend single-species platforms by introducing competing interaction scales and enhanced quantum fluctuations, enabling phenomena beyond homogeneou…
Improving the performance of quantum approximate optimization for preparing non-trivial quantum states without translational symmetry
Zheng-Hang Sun, Yong-Yi Wang, Jian Cui +1
The variational preparation of complex quantum states using the quantum approximate optimization algorithm (QAOA) is of fundamental interest, and becomes a promising application of…
Detecting Confined and Deconfined Spinons in Dynamical Quantum Simulations
Qiaoyi Li, Jian Cui, Wei Li
Dynamical spin-structure factor (DSF) contains fingerprint information of collective excitations in interacting quantum spin systems. In solid state experiments, DSF can be measure…
Quantum information scrambling in the presence of weak and strong thermalization
Zheng-Hang Sun, Jian Cui, Heng Fan
Quantum information scrambling under many-body dynamics is of fundamental interest. The tripartite mutual information can quantify the scrambling via its negative value. Here, we f…
Diagonal entropy in many-body systems: Volume effect and quantum phase transitions
Zhengan Wang, Zheng-Hang Sun, Yu Zeng +4
We investigate the diagonal entropy(DE) of the ground state for quantum many-body systems, including the XY model and the Ising model with next nearest neighbour interactions. We f…
Optimal control of Rydberg lattice gases
Jian Cui, Rick van Bijnen, Thomas Pohl +2
We present optimal control protocols to prepare different many-body quantum states of Rydberg atoms in optical lattices. Specifically, we show how to prepare highly ordered many-bo…
