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.

科学家目前只能从原理上证明光子（光粒子）量子物理学所提供的强大优势，真正利用光子的奇异性质需要无条件工作的方法和设备。由于不可避免的损失，量子特性极其脆弱，该项目将通过开发创新的抗损失协议和设备来克服这一障碍，这些协议和设备无条件地显示和利用量子效应，适用于长距离应用和超精确测量。这项合作将把世界上最好的光子探测器带到澳大利亚，作为这项工作和未来研究的关键资源。
