金刚石单氮空位缺陷中心的超导腔总线

A superconducting cavity bus for single Nitrogen Vacancy defect centres in diamond

J. Twamley, S. D. Barrett

摘要:

电路QED已经证明了超导共面谐振器中捕获的单个微波光子与附近的超导量子比特之间的非常强的耦合。在这项工作中,我们将展示如何通过设计一种新型的互连,可以通过磁相互作用将超导谐振器与少量(也许是单个)电子自旋强连接起来。通过将电子自旋选择在金刚石中的氮空位中心内,可以使用微波和射频照射来执行该电子自旋的光学读出、极化和控制。更重要的是,通过利用氮空位中心与附近的13 C核,使用这种互连,人们有可能建立一个量子设备,其中核自旋量子位通过氮空位电子自旋通过超导总线相互作用连接在厘米距离上。

英文摘要:

Circuit-QED has demonstrated very strong coupling between individual microwave photons trapped in a superconducting coplanar resonator and nearby superconducting qubits. In this work we show how, by designing a novel interconnect, one can strongly connect the superconducting resonator, via a magnetic interaction, to a small number (perhaps single), of electronic spins. By choosing the electronic spin to be within a Nitrogen Vacancy centre in diamond one can perform optical readout, polarization and control of this electron spin using microwave and radio frequency irradiation. More importantly, by utilising Nitrogen Vacancy centres with nearby 13C nuclei, using this interconnect, one has the potential build a quantum device where the nuclear spin qubits are connected over centimeter distances via the Nitrogen Vacancy electronic spins interacting through the superconducting bus.
