Surface-Induced Spectral Broadening during Efficient Two-Photon Excitation of Cold Atoms near an Optical Nanofiber
Yuan Jiang, Xiaodong Qi, Nicolás Vera Paz +5
We report the experimental observation of the Cs 6S to 6D single-frequency two-photon transition at low excitation power using an optic…
LinSBFT: Linear-Communication One-Step BFT Protocol for Public Blockchains
Xiaodong Qi, Yin Yang, Zhao Zhang +2
This paper presents LinSBFT, a Byzantine Fault Tolerance (BFT) protocol with the capacity of processing over 2000 smart contract transactions per second in production. LinSBFT appl…
Gödel's Sentence Is An Adversarial Example But Unsolvable
Xiaodong Qi, Lansheng Han
In recent years, different types of adversarial examples from different fields have emerged endlessly, including purely natural ones without perturbations. A variety of defenses ar…
Concurrency Protocol Aiming at High Performance of Execution and Replay for Smart Contracts
Shuaifeng Pang, Xiaodong Qi, Zhao Zhang +2
Although the emergence of the programmable smart contract makes blockchain systems easily embrace a wider range of industrial areas, how to execute smart contracts efficiently beco…
Enhanced cooperativity for quantum-nondemolition-measurement--induced spin squeezing of atoms coupled to a nanophotonic waveguide
Xiaodong Qi, Yuan-Yu Jau, Ivan H. Deutsch
We study the enhancement of cooperativity in the atom-light interface near a nanophotonic waveguide for application to quantum nondemolition (QND) measurement of atomic spins. Here…
Dispersive response of atoms trapped near the surface of an optical nanofiber with applications to quantum nondemolition measurement and spin squeezing
Xiaodong Qi, Ben Q. Baragiola, Poul S. Jessen +1
We study the strong coupling between photons and atoms that can be achieved in an optical nanofiber geometry when the interaction is dispersive. While the Purcell enhancement facto…
Modeling and Deciphering on Two Spin-polariton Entanglement Experiments in NV Centers of Diamond
Xiaodong Qi
This work is a theoretical investigation on the spin-polariton (polarized single photon) entanglement in nitrogen vacancy (NV) centers in diamond in order to interpret the results…
