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.
