Observation of Floquet topological phases with large Chern numbers
Kai Yang, Shaoyi Xu, Longwen Zhou +7
One of the most intriguing advantage of Floquet engineering is to generate new phases with large topological invariants. In this work, we experimentally simulate a periodically que…
Beating the Standard Quantum Limit under Ambient Conditions with Solid-State Spins
Tianyu Xie, Zhiyuan Zhao, Xi Kong +10
Precision measurement plays a crucial role in all fields of science. The use of entangled sensors in quantum metrology improves the precision limit from the standard quantum limit…
Experimental study of quantum coherence decomposition and trade-off relations in a tripartite system
Zhe Ding, Ran Liu, Chandrashekar Radhakrishnan +6
Quantum coherence is the most fundamental of all quantum quantifiers, underlying other well-known quantities such as entanglement, quantum discord, and Bell correlations. It can be…
Nanoscale magnetic resonance imaging of proteins in a single cell
Pengfei Wang, Sanyou Chen, Maosen Guo +10
Magnetic resonance imaging (MRI) is a non-invasive and label-free technique widely used in medical diagnosis and life science research, and its success has benefited greatly from c…
Three-dimensional entanglement on a silicon chip
Liangliang Lu, Lijun Xia, Zhiyu Chen +9
Entanglement is a counterintuitive feature of quantum physics that is at the heart of quantum technology. High-dimensional quantum states offer unique advantages in various quantum…
Floquet dynamical quantum phase transitions
Kai Yang, Longwen Zhou, Wenchao Ma +8
Dynamical quantum phase transitions (DQPTs) are manifested by time-domain nonanalytic behaviors of many-body systems.Introducing a quench is so far understood as a typical scenario…
Experimental Observation of a Generalized Thouless Pump with a Single Spin
Wenchao Ma, Longwen Zhou, Qi Zhang +7
Adiabatic cyclic modulation of a one-dimensional periodic potential will result in quantized charge transport, which is termed the Thouless pump. In contrast to the original Thoule…
Experimental Test of Born's Rule by Inspecting Third-Order Quantum Interference on a Single Spin in Solids
Fangzhou Jin, Ying Liu, Jianpei Geng +7
As a fundamental postulate of quantum mechanics, Born's rule assigns probabilities to the measurement outcomes of quantum systems and excludes multi-order quantum interference. Her…
Experimental Demonstration of Uncertainty Relations for the Triple Components of Angular Momentum
Wenchao Ma, Bin Chen, Ying Liu +6
The uncertainty principle is considered to be one of the most striking features in quantum mechanics. In the textbook literature, uncertainty relations usually refer to the prepara…
Experimental test of non-classicality of quantum mechanics using an individual atomic solid-state quantum system
Xi Kong, Mingjun Shi, Mengqi Wang +12
Quantum mechanics provides a statistical description about nature, and thus would be incomplete if its statistical predictions could not be accounted for some realistic models with…
Experimental test of Heisenberg's measurement uncertainty relation based on statistical distances
Wenchao Ma, Zhihao Ma, Hengyan Wang +9
Incompatible observables can be approximated by compatible observables in joint measurement or measured sequentially, with constrained accuracy as implied by Heisenberg's original…
Resolving Remoter Nuclear Spins in a Noisy Bath by Dynamical Decoupling Design
Wenchao Ma, Fazhan Shi, Kebiao Xu +7
We experimentally resolve several weakly coupled nuclear spins in diamond using a series of novelly designed dynamical decoupling controls. Some nuclear spin signals, hidden by dec…
Experimental fault-tolerant universal quantum gates with solid-state spins under ambient conditions
Xing Rong, Jianpei Geng, Fazhan Shi +7
Quantum computation provides great speedup over its classical counterpart for certain problems. One of the key challenges for quantum computation is to realize precise control of t…
