  ...In her analysis of this scenario, Vaccaro has found that a "present" quantum state of a neutral kaon is a billion times more similar to its future quantum state than its past quantum state. This means the present state is more likely to evolve into the future than the past. "The overall effect is like a random walk with a strong bias in one direction," Vaccaro says. "We may sometimes step backwards, but on average we are moving forwards in time...

  ...If you want to learn how to define a Hermitian phase operator without getting into a whole lot of trouble you should read the first six chapters..."  "...no one professing expertise in modern quantum optics can afford not to read it...",
  G. Milburn, Australian Physics 46, 86 (2009).
  
  "...Since the commentary introductions to the chapters are well readable, this book can well serve as a textbook for people who have some fundamental knowledge in quantum optics...",
