Quantum non-locality with mass-entangled metastable helium atoms atoms

该项目的目的是使用超冷氦原子来测试量子纠缠的各个方面。亚稳态氦的独特性质将为这一基本量子性质提供重要的新知识。预期的结果包括测量质量纠缠原子之间的贝尔测试，以及使用量子纠缠态作为测试质量来测试弱等效原理（自由落体的普遍性）。这应该会带来好处，包括为试图统一量子力学和广义相对论的新理论提供输入，并将与新兴的量子技术相关，如更强大的量子计算或复杂系统的量子模拟。

The aim of this project is to use ultracold helium atoms to test aspects of quantum entanglement. The unique properties of metastable helium will provide significant new knowledge of this fundamental quantum property. Expected outcomes include measuring a Bell test between mass entangled atoms and testing the weak equivalence principle (the universality of free fall) using a quantum entangled state as the test masses. This should provide benefits including input into new theories that attempt to unify quantum mechanics with general relativity and will be relevant for emerging quantum technologies such as more powerful quantum computing or quantum simulation of complex systems.
