论文摘要
根据量子绝热定理,我们可以原则上从简单的哈密顿式的微不足道真空开始获得量子系统的真空。在具有有限的时间长度和非限时时间步长的实际绝热数字量子模拟中,我们只能获得近似真空,该真空被认为是真正真空和激发态的叠加。我们提出了一种改善近似真空的程序。
According to the quantum adiabatic theorem, we can in principle obtain a true vacuum of a quantum system starting from a trivial vacuum of a simple Hamiltonian. In actual adiabatic digital quantum simulation with finite time length and non-infinitesimal time steps, we can only obtain an approximate vacuum that is supposed to be a superposition of a true vacuum and excited states. We propose a procedure to improve the approximate vacuum.
