This project aims to engineer novel quantum electronic devices based on strongly-coupled, one-dimensional superconducting microcircuits. These will be realised using chains of nanoscale superconducting islands fabricated on a chip. The project expects to achieve a special type of insulating state, where individual charges can be transported one by one. This would be significant as a primary standard that precisely links time (or frequency) to charge. The project also aims to create a current mirror device, in which a supercurrent sent down one chain induces a reflected supercurrent in the other, forming the basis of a new superconducting quantum bit. Other devices will be used to study a simplified model related to high temperature superconductors.

该项目旨在设计基于强耦合一维超导微电路的新型量子电子器件。这些将使用芯片上制造的纳米级超导岛链来实现。该项目预计将实现一种特殊类型的绝缘状态，在这种状态下，单个电荷可以逐个运输。这作为精确地将时间(或频率)与充电联系在一起的主要标准将具有重要意义。该项目还旨在创造一种电流镜装置，在这种装置中，沿着一条链发送的超级电流在另一条链上感应反射的超级电流，形成新的超导量子比特的基础。其他设备将用于研究与高温超导体相关的简化模型。
