Quantum theory is incredibly successful, explaining the microscopic world with great accuracy, from the behaviour of subatomic particles to chemical reactions to solid-state electronics. There is not a single experimental finding challenging its predictions, and ever more quantum phenomena are exploited in technology, including interferometric sensing and quantum cryptography. In order to explore novel applications and test the validity of quantum physics at the macroscale researchers strive to prepare ever heavier and bigger objects in quantum superpositions. Experiments with levitated microscale particles are about to push this quest into uncharted waters.

微尺度粒子的量子实验

量子理论非常成功，可以非常准确地解释微观世界，从亚原子粒子的行为到化学反应再到固态电子学。没有一个实验发现挑战其预测，而且越来越多的量子现象在技术中得到利用，包括干涉传感和量子密码学。为了探索新的应用并在宏观尺度上测试量子物理学的有效性，研究人员努力在量子叠加中准备越来越重、越来越大的物体。悬浮微尺度粒子的实验即将把这一探索推向未知的领域。
