Since I sort of implied a series in the previous post, and I have no better ideas, here’s a look at Thursday’s DAMOP program:

Anatomy of a Conference: DAMOP Day 1
The conference I’m at this week is the annual meeting of the Division of Atomic, Molecular, and Optical Physics of the American Physical Society (which this year is joint with the Canadian version, the Division of Atomic and Molecular Physics and Photon Interactions, or “DAMPΦ.” The Greek letter is a recent addition– as recently as… Continue reading Anatomy of a Conference: DAMOP Day 1
Cooling a “Macroscopic” Object to Its Quantum Ground State
Several people have sent me links to news stories about last week’s Nature paper, “Quantum ground state and single-phonon control of a mechanical resonator.” (It was also presented at the March Meeting, but I didn’t go to that session). This is billed as the first observation of quantum phenomena with a “macroscopic” or “naked eye… Continue reading Cooling a “Macroscopic” Object to Its Quantum Ground State
Four Things Everybody Should Know About Quantum Physics
Derek Lowe has a post talking about things biologists should know about medicinal chemistry. It’s a good idea for a post topic, so I’m going to steal it. Not to talk about medicinal chemistry, or biologists, of course, but to talk about my own field, and what everyone– not just scientists– should know about quantum… Continue reading Four Things Everybody Should Know About Quantum Physics
Poll: The Computers of the Future
Today’s Quantum Optics lecture is about quantum computing experiments, and how different types of systems stack up. Quantum computing, as you probably know if you’re reading this blog, is based on building a computer whose “bits” can not only take on “0” and “1” states, but arbitrary superpositions of “0” and “1”. Such a computer… Continue reading Poll: The Computers of the Future
The Early Days of Quantum Engineering
Buried in the weekend links dump at the arxiv blog was Scalable ion traps for quantum information processing: We report on the design, fabrication, and preliminary testing of a 150 zone array built in a `surface-electrode’ geometry microfabricated on a single substrate. We demonstrate transport of atomic ions between legs of a `Y’-type junction and… Continue reading The Early Days of Quantum Engineering
Quantum Computing in Diamond, on the Arxiv Blog
As I understand it, the Physics ArXiv Blog is not affiliated with the people who actually run the Arxiv (Paul Ginsparg et al.). Which is probably good, as I’m never entirely sure how seriously to take the papers they highlight. Take yesterday’s post, Diamond Challenges for Quantum-Computing Crown, which is about a paper that asks… Continue reading Quantum Computing in Diamond, on the Arxiv Blog
Transporting Ions Through an X-Junction: Quantum Computing Inches Closer
Physics World has a nice news article about a new experimental development in quantum computing, based on a forthcoming paper from the Wineland group at NIST in Boulder. I’d write this up for ResearchBlogging, but it’s still just on the arxiv, and I don’t think they’ve started accepting arxiv papers yet. The Physics World piece… Continue reading Transporting Ions Through an X-Junction: Quantum Computing Inches Closer
Congratulations to Cirac and Zoller
I’m not sure what the BBVA Foundation is, but they’ve awarded a Basic Science prize to Ignacio Cirac and Peter Zoller: The Basic Sciences award in this inaugural edition of the BBVA Foundation Frontiers of Knowledge Awards has been shared by physicists Peter Zoller (Austria, 1952) and Ignacio Cirac (Manresa, 1965), “for their fundamental work… Continue reading Congratulations to Cirac and Zoller
The Prestige for Ytterbium: Quantum Teleportation with Separated Atoms
My graduate alma mater made some news this week, with a new quantum teleportation experiment in which they “teleport” the state of one ytterbium ion to another ytterbium ion about a meter away. That may not sound like much, but it’s the first time anybody has done this with ions in two completely separate traps,… Continue reading The Prestige for Ytterbium: Quantum Teleportation with Separated Atoms
