量子系统的纠缠通常受其耦合哈密顿量和初始状态属性的限制。在此，我们通过对隧道耦合玻色子场模式的精确分析证明，因式分解的多玻色子双模态可通过双模耦合的频闪符号翻转实现完全纠缠。其纠缠可随翻转次数指数增长。除特定禁止态外，此效应普遍适用于双模态制备，可为多种量子技术应用提供纠缠资源。
英文摘要
The entanglement of quantum systems is commonly restricted by their coupling Hamiltonian and initial state properties. Here, we prove by exact analysis of tunnel-coupled bosonic field modes, that factorized multi-boson two-mode states can become fully entangled via stroboscopic sign flips of the two-mode coupling. Their entanglement can exponentially grow with the number of flips. With the exception of specific prohibitive states that are invariant under such sign-flip control, this effect universally applies to two-mode state preparation. Remarkably, this linear control may provide entanglement resources for diverse quantum technological applications by readily available means.
