Quantum supremacy, a term coined by John Preskill in 2012, refers to the point at which quantum computers can perform tasks beyond the reach of classical computers. Universal quantum computation, a theoretical concept where a quantum computer could efficiently solve any problem that a classical computer can solve, is a significant milestone in the field

In the realm of quantum information, a qubit, the fundamental unit of quantum information, can indeed be conceptualized as undergoing state rotations during its evolution. This notion stems from the inherent quantum mechanical properties of qubits, which allow them to exist in superpositions of classical states, unlike classical bits that can only be in one

Can quantum entanglement be induced by local interaction?
In the realm of quantum mechanics, quantum entanglement is a phenomenon where two or more particles become interconnected in such a way that the state of one particle cannot be described independently of the state of the others, even when separated by vast distances. This phenomenon has been a subject of intense study due to

Shor 的量子因式分解演算法總是能以指數方式加速找出大數的質因數嗎?
與經典演算法相比,Shor 的量子因式分解演算法確實在尋找大數素因數方面提供了指數級的加速。該演算法由數學家 Peter Shor 於 1994 年開發,是量子計算領域的關鍵進步。它利用疊加和糾纏等量子特性來實現質因數分解的顯著效率。在經典計算中,
