Quantum Spottings

Quantum ghosts, dynamical decoupling, why a diamond is forever in quantum computing, transversal press, quantum phrases I can’t grok, and quantum jumping.

  • Quantum ghosts: here and here. These articles describe the work reported in Laing, Rudolph, and O’Brien. “Experimental Quantum Process Discrimination.” Phys. Rev. Lett., 102, 160502 (2009) arXiv:0801.3831. The idea is to discriminate “non-orthogonal” quantum processes via the use of entanglement, which is cool. (I’m a bit surprised that this classic paper is not referenced.)
  • Optimized dynamical decoupling performed in ions at NIST. Paper published in Nature: Biercuk, Uys, Van Devender, Shiga, Itano, and Bollinger, “Optimized dynamical decoupling in a model quantum memory” Nature 458, 996-1000 (2009). Press here and here.
  • Words I should probably understand, but don’t: Quantum vertical leap, quantum growth, quantum bit induction.
  • UCSB scores some big dollars, $6 million, for diamond quantum computing research.
  • Describing transversal gate sets is not going to be easy if you want it to be comprehensible to the public. This is one such attempted describing the Eastin-Knill theorem.
  • Quantum design theory:

    The essence of quantum design theory is knowing that your walls, your rug, your artwork — all of your possessions — do give off energy, and each piece does its part to contribute to the mood in a room.

  • And last, but not least, quantum jumping: “is the process of ‘jumping’ into parallel dimensions, and gaining skills, knowledge, wisdom and inspiration from alternate versions of yourself.” See that’s my problem, I keep destructively interfering with myself when I perform a quantum jump.

  1. Well, that’s what you get when you just feed the Google Alerts for “quantum” into your blog without any filtering. Someone should tell the cranks that “quantum design” and “quantum jump” are already in use for non-crackpot purposes.
