商品描述
Today's computers-both in theory (Turing machines) and practice (PCs)-are based on classical physics. However, modern quantum physics tells us that the world behaves quite differently. A quantum system can be in a superposition of many different states at the same time, and can exhibit interference effects during the course of its evolution. Moreover, spatially separated quantum systems may be entangled with each other and operations may have "non-local" effects because of this. Quantum computation is the field that investigates the computational power and other properties of computers based on quantum-mechanical principles. An important objective is to find quantum algorithms that are significantly faster than any classical algorithm solving the same problem.
商品描述(中文翻譯)
今天的電腦——無論是在理論上（圖靈機）還是在實踐中（個人電腦）——都是基於經典物理學。然而，現代量子物理告訴我們，世界的運作方式截然不同。量子系統可以同時處於多種不同狀態的疊加中，並且在其演化過程中可以顯示出干涉效應。此外，空間上分離的量子系統可能彼此糾纏，因而操作可能會因這一點而產生「非局部」的效應。量子計算是研究基於量子力學原則的電腦的計算能力及其他特性的領域。一個重要的目標是尋找顯著快於任何經典算法的量子算法，以解決相同的問題。
