Compact lightweight high performance magnetic shielding enabling portable & miniaturised quantum technology systems - "QT-Shield"

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。现有的磁屏蔽既笨重又笨重，为实现便携和微型量子设备制造了障碍。屏蔽是专为每种应用而设计的，通常生产量很小。目前，生产是在机械加工车间手工进行的；因此限制了生产销售，并造成了对国外低工资经济的脆弱性。Qt-Shield解决方案寻求应用先进的屏蔽设计原则，实现高性能紧凑轻便的磁屏蔽，与传统方法相比，重量减轻了50%，体积减少了40%。屏蔽将使用先进制造工艺的组合来制造；实现大批量定制屏蔽件的自动化生产。Qt-Shield将通过将先进的屏蔽应用于量子重力传感器演示系统的保护来证明这种方法的可行性。

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.
