论文摘要
我们证明，单轴扭曲（OAT）是一种创建玻色粒量子的非经典状态的多功能方法，是多体钟相关的强大来源。我们开发了该过程的完全分析和普遍处理，这使我们能够确定钟形相关性出现的关键时间，并在随后的所有时间预测钟形相关性的深度。我们的发现以使用Bose-Hubbard模型生成的燕麦动力学的高度非平凡的例子进行了说明。
We demonstrate that the one-axis twisting (OAT), a versatile method of creating non-classical states of bosonic qubits, is a powerful source of many-body Bell correlations. We develop a fully analytical and universal treatment of the process, which allows us to identify the critical time at which the Bell correlations emerge, and predict the depth of Bell correlations at all subsequent times. Our findings are illustrated with a highly non-trivial example of the OAT dynamics generated using the Bose-Hubbard model.
