Topological eigenvalues braiding and quantum state transfer near a third-order exceptional point
He Zhang, Tong Liu, Zhongcheng Xiang +3
Non-Hermitian systems exhibit a variety of unique features rooted in the presence of exceptional points (EP). The distinct topological structure in the proximity of an EP gives ris…
Synthetic multi-dimensional Aharonov-Bohm cages in Fock state lattices
Jiajian Zhang, Wenhui Huang, Ji Chu +13
Fock-state lattices (FSLs), composed of photon number states with infinite Hilbert space, have emerged as a promising platform for simulating high-dimensional physics due to their…
Quantum tomography of a third-order exceptional point in a dissipative trapped ion
Y. -Y. Chen, K. Li, L. Zhang +9
The requirement for Hermiticity in quantum mechanics ensures the reality of energies, while the parity-time symmetry offers an alternative route to achieve this goal. Interestingly…
Experimental certification of high-dimensional entanglement with randomized measurements
Ohad Lib, Shuheng Liu, Ronen Shekel +4
High-dimensional entangled states offer higher information capacity and stronger resilience to noise compared with two-dimensional systems. However, the large number of modes and s…
Optimal estimation of three parallel spins with genuine and restricted collective measurements
Changhao Yi, Kai Zhou, Zhibo Hou +2
Collective measurements on identical and independent quantum systems can offer advantages in information extraction compared with individual measurements. However, little is known…
Contractive Unitary and Classical Shadow Tomography
Yadong Wu, Ce Wang, Juan Yao +3
The rapid development of quantum technology demands efficient characterization of complex quantum many-body states. However, full quantum state tomography requires an exponential n…
