量子计算机的算力可体现为量子计算机可实现并行计算, Grover算法(Quantum Search Algorithm)是量子计算领域的主要算法之一。Grover算法是由Grover于1996年提出的平方根加速的随机数据库量子搜索算法,旨在利用量子计算机进行比经典计算机更快的数据搜索。在数据库足够混乱且没有具体的数据结构限定的条件下,Grover算法可以快速解决...

Grover algorithm is a quantum search algorithm that can find the target state efficiently. However, with the increase in the amount of searching data, the circuit of Grover algorithm is faced with complex gate decomposition problem. In today's NISQ era, resources are very limited, so the depth...

Secondly, as underscored in22, the runtime of quantum algorithms predominantly hinges on T-depth rather than gate count, circuit depth, or measurement depth. Therefore, optimizing T-depth emerges as critical for achieving efficient execution. Certainly, Grover's algorithm faces limitations in ...
