标题： Quantum search by parallel eigenvalue adiabatic passage

摘要： 我们提出一种策略，通过绝热跃迁非常高效地实现Grover搜索算法。 一个绝热过程可以通过相关哈密顿量的瞬时本征值来表征，其中一些本征值形成一个能隙。 效率的关键在于使用并行本征值。 这使我们能够获得指数级小的非绝热损失，而与搜索数据库中的条目数量无关。 显示英文摘要

摘要： We propose a strategy to achieve the Grover search algorithm by adiabatic passage in a very efficient way. An adiabatic process can be characterized by the instantaneous eigenvalues of the pertaining Hamiltonian, some of which form a gap. The key to the efficiency is based on the use of parallel eigenvalues. This allows us to obtain non-adiabatic losses which are exponentially small, independently of the number of items in the database in which the search is performed.
