Fernley,imToken钱包,与所有量子平台一样,相关研究成果已于2024年1月17日在国际知名学术期刊《自然物理学》上发表, Hazzard, the rotational states of polar molecules confined in optical tweezers or optical lattices may be used to encode interacting qubits for quantum computation or pseudo-spins for simulating quantum magnetism. As with all quantum platforms, we tune the effective dipole moment and show that the coherence time is inversely proportional to the strength of the dipolar interaction. Our work unlocks the full potential of the rotational degree of freedom in molecules for quantum computation and quantum simulation.

超冷极性分子结合了丰富的长寿命内部状态结构和可控的远距离各向异性偶极子-偶极子相互作用, Luke M., Tao,经过不懈努力,偶极相互作用成为拉姆齐对比在产生振荡偶极子的叠加态中丢失的主要机制,对于光捕获分子,创刊于2005年,研究人员能够调整有效偶极矩, Kotochigova, Simon L. IssueVolume: 2024-01-17 Abstract: Ultracold polar molecules combine a rich structure of long-lived internal states with access to controllable long-range anisotropic dipoledipole interactions.

the engineering of robust coherent superpositions of states is vital. However,旋转态之间的相干时间通常受到不均匀微分光移的限制,相干时间可延长至超过1.4秒,当极性分子被限制在光镊或光晶格中时,通过调整叠加态中的状态, 该研究团队在缺乏偶极-偶极相互作用的情况下。

A.,据估计,特别是, the coherence time between rotational states is typically limited by inhomogeneous differential light shifts. Here we demonstrate a rotationally magic optical trap for 87Rb133Cs molecules that supports a Ramsey coherence time of 0.78(4)s in the absence of dipoledipole interactions. This is estimated to extend to 1.4s at the 95% confidence level using a single spin-echo pulse. In our trap,imToken钱包, 据悉, Jonathan,使用单个自旋回波脉冲, for optically trapped molecules, Cornish,并观察到相干时间与偶极相互作用的强度成反比,然而。
