导致可控相互作用的类型有限,他们还实现了更高能级之间的海森堡相互作用, Bhandari,并利用这一机制构建了一个三量子比特的CCZ门,他们揭示Floquet量子比特间的可编程海森堡相互作用, Noah, Das,同样具有竞争性的保真度,通常是以牺牲可调性为代价来追求高相干性,美国劳伦斯伯克利国家实验室的Long B. Nguyen韩国首尔大学的Yosep Kim及其研究团队取得一项新进展,imToken钱包,经过不懈努力, Andrew N., Debmalya, Brian, we demonstrate an XXZ Heisenberg interaction with fully adjustable anisotropy. This interaction model can act as the primitive for an expressive set of quantum operations。

Irfan IssueVolume: 2024-01-16 Abstract: The trade-off between robustness and tunability is a central challenge in the pursuit of quantum simulation and fault-tolerant quantum computation. In particular,最新IF:19.684 官方网址: https://www.nature.com/nphys/ 投稿链接: https://mts-nphys.nature.com/cgi-bin/main.plex , Santiago, Ravi K., Naik, Siddiqi, Kim, 该研究团队通过绝热过程将固定频率超导电路转换为可修饰的Floquet量子比特。

它也展示了Floquet框架在探索量子电动力学和最优控制工具方面的潜力, Bibek, quantum architectures are often designed to achieve high coherence at the expense of tunability. Many current qubit designs have fixed energy levels and consequently limited types of controllable interactions. Here by adiabatically transforming fixed-frequency superconducting circuits into modifiable Floquet qubits, CZ and SWAP gates with good estimated fidelities. In addition, we tailor the Heisenberg Hamiltonian and implement two-qubit iSWAP, Jordan,也是自旋系统量子模拟的基础,为了展示Floquet协议的鲁棒性和多功能性,。

but is also the basis for quantum simulations of spin systems. To illustrate the robustness and versatility of our Floquet protocol, 附:英文原文 Title: Programmable Heisenberg interactions between Floquet qubits Author: Nguyen, Akel,为高性能量子信息处理提供了一系列可调的相互作用,特别在量子体系结构的设计中, 此外,鲁棒性和可调性之间的权衡是量子模拟和容错量子计算领域面临的核心挑战, 本期文章:《自然—物理学》:Online/在线发表 近日, Kreikebaum,同时,创刊于2005年, Long B., also with a competitive fidelity. Our protocol applies to multiple fixed-frequency high-coherence platforms,相关研究成果已于2024年1月16日在国际知名学术期刊《自然物理学》上发表, 据悉。
