Nitrogen-Vacancy Center as Open-Quantum-System Simulator
Chao Lei, Shijie Peng, Chenyong Ju +2
Quantum mechanical systems lose coherence through interactions with external environments---a process known as decoherence. Although decoherence is detrimental for most of the task…
Direct measurement of topological numbers with spins in diamond
Fei Kong, Chenyong Ju, Ying Liu +9
Topological numbers can characterize the transition between different topological phases, which are not described by Landau's paradigm of symmetry breaking. Since the discovery of…
Experimental observation of topological transitions in interacting multi-spin systems
Zhihuang Luo, Chao Lei, Jun Li +4
Topologically ordered phase has emerged as one of most exciting concepts that not only broadens our understanding of phases of matter, but also has been found to have potential app…
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…
Search via Quantum Walk
Frédéric Magniez, Ashwin Nayak, Jérémie Roland +1
We propose a new method for designing quantum search algorithms for finding a "marked" element in the state space of a classical Markov chain. The algorithm is based on a quantum w…
