Scientists can currently only give in-principle demonstrations of the powerful advantages offered by the quantum physics of photons – particles of light. A true quantum technology revolution, that genuinely exploits photons’ exotic nature, requires methods and apparatus that work unconditionally. The main barrier is the extreme fragility of quantum properties due to unavoidable losses. This project will overcome this barrier by developing innovative loss-tolerant protocols and devices that unconditionally show and exploit quantum effects, both for long-distance applications and ultra-precise measurement technologies. This collaboration will bring the world’s best photon detectors to Australia, as a key resource for this work and for future research.

目前，科学家只能对照片的量子物理学（光颗粒粒子）提供的强大优势进行原则演示。真正的量子技术革命，真正探讨了照片的异国性质，需要无条件起作用的方法和设备。主要的障碍是由于不可避免的损失，量子性质的极端脆弱性。该项目将通过开发具有创新损失的协议和设备来克服这一障碍，这些方案和设备无条件地显示和利用量子效应，包括长距离应用和超专业测量技术。这项合作将使世界上最好的光子探测器带到澳大利亚，这是这项工作和未来研究的关键资源。
