A chip-based superconducting magnetic trap for levitating superconducting microparticles
摘要：
磁悬浮的超导微粒最近被提出作为一个有前途的平台进行量子实验的粒子在皮克制度。在这里，我们展示了超导技术，以实现基于芯片的超导微粒的磁悬浮。我们模拟并制作了一个基于芯片的磁阱，能够悬浮直径从0.5 $\,μ$ m到200 $\,μ$ m的超导粒子。该陷阱由两个堆叠的硅芯片组成，每个硅芯片上都有一个由铌制成的平面多绕组超导线圈。两个线圈在陷阱中心附近产生类似四极的磁场，在其中我们演示了在4，K和40，mK温度下对直径为50，$μ$ m的球形SnPb微粒的捕获。
英文摘要：
Magnetically-levitated superconducting microparticles have been recently proposed as a promising platform for performing quantum experiments with particles in the picogram regime. Here, we demonstrate the superconducting technology to achieve chip-based magnetic levitation of superconducting microparticles. We simulate and fabricate a chip-based magnetic trap capable of levitating superconducting particles with diameters from 0.5$\,μ$m to 200$\,μ$m. The trap consists of two stacked silicon chips, each patterned with a planar multi-winding superconducting coil made of niobium. The two coils generate a magnetic field resembling a quadrupole near the trap center, in which we demonstrate trapping of a spherical 50\,$μ$m diameter SnPb microparticle at temperatures of 4\,K and 40\,mK.
