Beschreibung
Taking readers to the cutting edge of physics, mathematics, and computer science, Julian Brown tells the dramatic story of the groundbreaking efforts to create a fundamentally new kind of computer that would be astronomically more powerful than today's machines. In 1998, a team of researchers announced they had produced the world's first quantum computer in a cup of chloroform. In fascinating, fully accessible detail, Brown explains the ideas that led up to this accomplishment and explores the mind-stretching implications of this leap into the bizarre world of quantum physics. "The Quest for the Quantum Computer" is a riveting look at what promises to be one of the most important scientific and technological ideas of the twenty-first century.
