Creating a Quantum Superposition of Living Things

KentuckyFC writes "Having created quantum superpositions of photons, atoms, and even molecules, scientists are currently preparing to do the same for larger objects — namely viruses. The technique will involve storing a virus in a vacuum and then cooling it to its quantum-mechanical ground state in a microcavity. Zapping the virus with a laser then leaves it in a superposition of its ground state and an excited one. That's no easy task, however. The virus will have to survive the vacuum, behave like a dielectric, and appear transparent to the laser light, which would otherwise tear it apart. Now a group of researchers has worked out that several viruses look capable of surviving the superposition process, including the common flu virus and the tobacco mosaic virus. They point out that after creating the superposition, scientists will be able to perform the Schrodinger's Cat experiment for the first time, which should be fun (but less so for the virus)."

The researchers who work with viruses disagree

[JoshuaZ]

A lot of the researchers who work with viruses consider them to be alive. See for example this piece by Abbie Smith explaining why viruses should be considered to be alive and why most of the arguments against are not convincing: http://scienceblogs.com/erv/2009/03/ten_five_reasons_clumsy_excuse.php. The people who argue that viruses aren't alive are almost inevitably non-biologists or biologists who don't work with viruses.

You know what else is common consensus? The plural of "virus" is "viruses".
