Magnetic shielding is an essential component of all second generation quantum technology systems necessary to eliminate magnetic interference and enable quantum behaviour to be observed. A particular challenge for quantum systems is shielding of low frequency and DC magnetic fields. Existing magnetic shielding is bulky and heavy creating barriers to the realisation of portable and miniaturised quantum devices. Shielding is uniquely designed for each application, often with low production volume. Production is currently undertaken by hand in machining workshops; thereby limiting production sale-up and creating a vulnerability to low wage economies abroad. The QT-Shield solution seeks to apply advanced shielding design principles for the realisation of high performance compact-lightweight magnetic shielding delivering a >50% reduction in weight and >40% reduction in volume compared to conventional approaches. Shielding will be manufactured using a combination of advanced manufacturing processes; enabling automated production of customised shields at high volume. QT-Shield will demonstrate the feasibility of this approach through application of the advanced shielding for protection of a quantum gravity sensor demonstrator system.

磁屏蔽是所有第二代量子技术系统的重要组成部分，是消除磁干扰和观察量子行为所必需的。量子系统面临的一个特殊挑战是屏蔽低频和直流磁场。现有的磁屏蔽体积庞大且笨重，为实现便携式和小型化量子设备造成了障碍。屏蔽针对每种应用进行独特设计，通常产量较低。目前，生产是在机加工车间手工进行的；从而限制了生产销售并造成了对国外低工资经济体的脆弱性。 QT-Shield 解决方案旨在应用先进的屏蔽设计原理，实现高性能、紧凑、轻量级磁屏蔽，与传统方法相比，重量减轻 50% 以上，体积减少 40% 以上。屏蔽层将采用先进制造工艺的组合来制造；实现大批量定制防护罩的自动化生产。 QT-Shield 将通过应用先进的屏蔽来保护量子重力传感器演示系统，展示这种方法的可行性。
