Spontaneous decay induced quantum dynamics in Rydberg blockaded Λ-type atoms
Chang Qiao, Wenxian Zhang
Strongly Rydberg-blockaded two-level atoms form a Rydberg superatom, which is excited only to a collective symmetrical Dicke state. However, emerging often in the alkali-earth atom…
Selective quantum Zeno effect of ultracold atom-molecule scattering in dynamic magnetic fields
Hanwei Yang, Zunqi Li, Songbin Zhang +6
We demonstrated that final states of ultracold scattering between atom and molecule can be selectively produced using dynamic magnetic fields of multiple frequencies. The mechanism…
Quantum secure direct communication with private dense coding using general preshared quantum state
Jiawei Wu, Gui-Lu Long, Masahito Hayashi
We study quantum secure direct communication by using a general preshared quantum state and a generalization of dense coding. In this scenario, Alice is allowed to apply a unitary…
When can a local Hamiltonian be recovered from a steady state?
Jing Zhou, D. L. Zhou
With the development of quantum many-body simulator, Hamiltonian tomography has become an increasingly important technique for verification of quantum devices. Here we investigate…
Quantum phases transition revealed by the exceptional point in Hopfield-Bogoliubov matrix
Dong Xie, Chunling Xu, An Min Wang
We use the exceptional point in Hopfield-Bogoliubov matrix to find the phase transition points in the bosonic system. In many previous jobs, the excitation energy vanished at the c…
Remote generation of magnon Schrödinger cat state via magnon-photon entanglement
Feng-Xiao Sun, Sha-Sha Zheng, Yang Xiao +3
Magnon cat state represents a macroscopic quantum superposition of collective magnetic excitations of large number spins that not only provides fundamental tests of macroscopic qua…
Quantum Computing by Cooling
Jiajin Feng, Biao Wu, Frank Wilczek
Interesting problems in quantum computation take the form of finding low-energy states of (pseudo)spin systems with engineered Hamiltonians that encode the problem data. Motivated…
Quantum state tomography of molecules by ultrafast diffraction
Ming Zhang, Shuqiao Zhang, Yanwei Xiong +9
Ultrafast electron diffraction and time-resolved serial crystallography are the basis of the ongoing revolution in capturing at the atomic level of detail the structural dynamics o…
Detecting Einstein-Podolsky-Rosen steering in non-Gaussian spin states from conditional spin-squeezing parameters
Jiajie Guo, Feng-Xiao Sun, Daoquan Zhu +3
We present an experimentally practical method to reveal Einstein-Podolsky-Rosen steering in non-Gaussian spin states by exploiting a connection to quantum metrology. Our criterion…
Ghost imaging with non-Gaussian quantum light
Dongyu Liu, Mingsheng Tian, Shuheng Liu +5
Non-local point-to-point correlations between two photons have been used to produce "ghost" images without placing the camera towards the object. Here we theoretically demonstrated…
A generalised multipath delayed-choice experiment on a large-scale quantum nanophotonic chip
Xiaojiong Chen, Yaohao Deng, Shuheng Liu +15
Famous double-slit or double-path experiments, implemented in a Young's or Mach-Zehnder interferometer, have confirmed the dual nature of quantum matter, When a stream of photons,…
Quantum imaginary time evolution steered by reinforcement learning
Chenfeng Cao, Zheng An, Shi-Yao Hou +2
The quantum imaginary time evolution is a powerful algorithm for preparing the ground and thermal states on near-term quantum devices. However, algorithmic errors induced by Trotte…
Quantification of Wigner Negativity Remotely Generated via Einstein-Podolsky-Rosen Steering
Yu Xiang, Shuheng Liu, Jiajie Guo +4
Wigner negativity, as a well-known indicator of nonclassicality, plays an essential role in quantum computing and simulation using continuous-variable systems. Recently, it has bee…
Deterministic quantum one-time pad via Fibonacci anyons
Cheng-Qian Xu, D. L. Zhou
Anyonic states, which are topologically robust originated from their peculiar structure of Hilbert space, have important applications in quantum computing and quantum communication…
Transfer matrix study of the Anderson transition in non-Hermitian systems
Xunlong Luo, Tomi Ohtsuki, Ryuichi Shindou
In this paper, we present in-depth transfer matrix analyses of the Anderson transition in three non-Hermitian (NH) systems, NH Anderson, U(1) and Peierls models, that belong to NH…
Microscope for Quantum Dynamics with Planck Cell Resolution
Zhenduo Wang, Jiajin Feng, Biao Wu
We introduce the out-of-time-correlation(OTOC) with the Planck cell resolution. The dependence of this OTOC on the initial state makes it function like a microscope, allowing us to…
Deterministic distribution of multipartite entanglement and steering in a quantum network by separable states
Meihong Wang, Yu Xiang, Haijun Kang +6
As two valuable quantum resources, Einstein-Podolsky-Rosen entanglement and steering play important roles in quantum-enhanced communication protocols. Distributing such quantum res…
