商品描述

An accessible introduction to an exciting new area in computation, explaining such topics as qubits, entanglement, and quantum teleportation for the general reader.

Quantum computing is a beautiful fusion of quantum physics and computer science, incorporating some of the most stunning ideas from twentieth-century physics into an entirely new way of thinking about computation. In this book, Chris Bernhardt offers an introduction to quantum computing that is accessible to anyone who is comfortable with high school mathematics. He explains qubits, entanglement, quantum teleportation, quantum algorithms, and other quantum-related topics as clearly as possible for the general reader. Bernhardt, a mathematician himself, simplifies the mathematics as much as he can and provides elementary examples that illustrate both how the math works and what it means.

Bernhardt introduces the basic unit of quantum computing, the qubit, and explains how the qubit can be measured; discusses entanglement―which, he says, is easier to describe mathematically than verbally―and what it means when two qubits are entangled (citing Einstein's characterization of what happens when the measurement of one entangled qubit affects the second as “spooky action at a distance”); and introduces quantum cryptography. He recaps standard topics in classical computing―bits, gates, and logic―and describes Edward Fredkin's ingenious billiard ball computer. He defines quantum gates, considers the speed of quantum algorithms, and describes the building of quantum computers. By the end of the book, readers understand that quantum computing and classical computing are not two distinct disciplines, and that quantum computing is the fundamental form of computing. The basic unit of computation is the qubit, not the bit.

商品描述(中文翻譯)

一本對於量子計算的易懂介紹,解釋了量子位元、纏結和量子傳輸等主題,適合一般讀者閱讀。

量子計算是量子物理學和計算機科學的美麗結合,將二十世紀物理學中最令人驚嘆的想法融入到一種全新的計算思維方式中。在這本書中,Chris Bernhardt向任何對高中數學感到舒適的人介紹了量子計算。他以盡可能清晰的方式解釋了量子位元、纏結、量子傳輸、量子算法和其他與量子相關的主題。作為一位數學家,Bernhardt盡量簡化數學,並提供了基本的例子,既說明了數學的運作方式,又說明了其含義。

Bernhardt介紹了量子計算的基本單位-量子位元,並解釋了如何測量量子位元;討論了纏結-他說數學上比口頭上更容易描述-以及當兩個量子位元被纏結時的含義(引用愛因斯坦對於當測量一個纏結的量子位元時如何影響第二個的描述,稱之為“遠距離的詭異行為”);並介紹了量子密碼學。他回顧了傳統計算的標準主題-位元、閘和邏輯-並描述了Edward Fredkin巧妙的撞球計算機。他定義了量子閘,考慮了量子算法的速度,並描述了量子計算機的構建。通過閱讀本書,讀者將理解量子計算和傳統計算不是兩個不同的學科,而是量子計算是計算的基本形式。計算的基本單位是量子位元,而不是位元。
