While reviewing this book, I designed and delivered a first-year undergraduate computing lecture and workshop drawing on its content, with excellent impact A masterpiece that should be read by all who are interested in quantum computing.</P> (<B>Colin Price</B> <i><I>Times Higher Education</I></i>)<br /><br /><P>[ <I>Quantum Computing</I>] offers one of the best introductions to the themes and concepts of quantum measurement that I have ever read...The authors have the rare capacity of offering us a steady quality of educational throughput, regardless of the inherent difficulty of the theme presented...It is a significant education oeuvre.</P> (<B>Constantin S.

The book should be a good addition to the educational literature on the subject.</P> (<B>Karoline Wiesner</B>, School of Mathematics and Center for Complexity Science, University of Bristol)

  Abstract: Quantum random number generators are widely used in many applications, ranging from
  sampling and simulation, fundamental science to cryptography, such as a quantum key distribution
  system. Among all the previous works, quantum noise from phase ﬂu
