Observation of Non-Markovianity at Room Temperature by Prolonging Entanglement in Solids
Shijie Peng, Xiangkun Xu, Kebiao Xu +7
The non-Markovia dynamics of quantum evolution plays an important role in open quantum sytem. However, how to quantify non-Markovian behavior and what can be obtained from non- Mar…
Breaking the quantum adiabatic speed limit by jumping along geodesics
Kebiao Xu, Tianyu Xie, Fazhan Shi +6
Quantum adiabatic evolutions find a broad range of applications in quantum physics and quantum technologies. The traditional form of the quantum adiabatic theorem limits the speed…
Experimental Adiabatic Quantum Factorization under Ambient Conditions Based on a Solid-State Single Spin System
Kebiao Xu, Tianyu Xie, Zhaokai Li +8
The adiabatic quantum computation is a universal and robust method of quantum computing. In this architecture, the problem can be solved by adiabatically evolving the quantum proce…
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…
NV-Center Based Digital Quantum Simulation of a Quantum Phase Transition in Topological Insulators
Chenyong Ju, Chao Lei, Xiangkun Xu +3
Nitrogen-vacancy centers in diamond are ideal platforms for quantum simulation, which allows one to handle problems that are intractable theoretically or experimentally. Here we pr…
Observation of Time-domain Rabi Oscillations in the Landau-Zener Regime with a Single Electronic Spin
Jingwei Zhou, Pu Huang, Qi Zhang +7
Under resonant conditions, a long sequence of landau-zener transitions can lead to Rabi oscillations. Using a nitrogen-vacancy (NV) center spin in diamond, we investigated the inte…
