말뭉치

  1. On the other hand, quantum chaos describes chaotic classical dynamical systems in terms of quantum theory.[1]
  2. Quantum chaos is responsible for the scrambling of information occurring in complex systems such as blackholes.[1]
  3. Thus, one could leverage balanced energy gain and loss as an experimental tool not only to probe quantum chaos but to study many-body quantum systems in general.[1]
  4. "Decoherence limits quantum computing, so it follows that because increasing quantum chaos reduces decoherence, you can keep computing longer," Saxena said.[1]
  5. Quantum chaos is a branch of physics which studies how chaotic classical dynamical systems can be described in terms of quantum theory.[2]
  6. Quantum chaos typically deals with systems whose properties need to be calculated using either numerical techniques or approximation schemes (see e.g. Dyson series).[2]
  7. Nevertheless, learning how to solve such quantum problems is an important part of answering the question of quantum chaos.[2]
  8. Statistical measures of quantum chaos were born out of a desire to quantify spectral features of complex systems.[2]
  9. I must emphasize, however, that the term "quantum chaos" serves more to describe a conundrum than to define a well-posed problem.[3]
  10. Considering the following interpretation of the bigger picture may be helpful in coming to grips with quantum chaos.[3]
  11. Quantum chaos is concerned with establishing the relation between boxes P (chaotic systems) and Q (quantum systems).[3]
  12. "At present this seems to be the best textbook on quantum chaos.[4]
  13. The book is based on lectures on classical and quantum chaos held by the author at Heidelberg University.[5]
  14. Quantum chaos began as an attempt to nd chaos, in the sense of extreme sensitivity to in quantum me- changes in initial conditions, chanical systems.[6]
  15. These are some of the questions that quantum chaos tries to answer.[6]
  16. This book, however, is one of the first to deal with quantum chaos, the natural progression from such classical systems.[7]
  17. In this book the author deals with three major issues in quantum chaos.[7]
  18. The primary issues in quantum chaos in a three-body system are what are the signs of chaos, and how large the quantum system has to be to display chaotic behavior.[8]
  19. In quantum chaos, trajectories do not diverge exponentially because they are constrained by the fact that the entire evolution must be unitary.[9]
  20. Several signatures have been studied in the literature to identify quantum chaos but all of them fall short in some way or the other.[10]
  21. Then, we will discuss a few well-studied signatures of quantum chaos and the subtleties associated with them.[10]
  22. There are some major differences between classical and quantum mechanics, and these differences are important for our discussion of quantum chaos.[11]
  23. “Our work challenges the expectation that decoherence generally suppresses quantum chaos,” Saxena said.[12]
  24. Decoherence limits quantum computing, so it follows that because increasing quantum chaos reduces decoherence, you can keep computing longer,” Saxena said.[12]
  25. The subject of quantum chaos is an active field of research in which many basic issues still require clarification.[13]
  26. A novel quantity to measure quantum chaos in spectra is proposed and a conjecture about its universal statistical behaviour is put forward.[14]
  27. There thus exists no quantum chaos (QC`} that manifests itself in the long-time behaviour of the dynamics.[14]
  28. This experiment has been carried out by the team of J. C. Garreau and P. Szriftgiser (quantum chaos group of the PhLAM lab).[15]
