量子纠缠态的叠加态可以根据张量积分离吗?
In quantum mechanics, entanglement is a phenomenon where two or more particles become connected in such a way that the state of one particle cannot be described independently of the state of the others, even when they are separated by large distances. This phenomenon has been a subject of great interest due to its non-classical

退相干不能用量子系统与其周围环境纠缠来解释吗?
Decoherence in quantum systems is a fundamental concept that plays a crucial role in the behavior and understanding of quantum systems. The process of decoherence occurs when a quantum system interacts with its surrounding environment, leading to the loss of coherence and the emergence of classical behavior. This phenomenon is essential to consider when investigating

Grover 的量子搜索算法是否会指数级加速索引搜索问题?
Grover's quantum search algorithm indeed introduces an exponential speedup in the index search problem when compared to classical algorithms. This algorithm, proposed by Lov Grover in 1996, is a quantum algorithm that can search an unsorted database of N entries in O(√N) time complexity, whereas the best classical algorithm, the brute-force search, requires O(N) time
