Quantum Superpositioning: Like Kids with ADHD, both excited and grounded.

Scientists at the Max-Planck-Institut fur Quantenoptik in Germany(Max Plank Institute for Quantum Optics) are proposing a bold new experiment dealing with quantum super-positioning. What they propose to do is to place a virus into a superposition.

What super-positioning means is when something is in two or more states at the same time. The classic analogy is known as the Schroedinger cat experiment. This is a thought-experiment(meaning its never been performed in real life, but only in the mind) where a cat is placed in a box, where a poison will be released only if a radioactive object decays within the time period inside the box. The decay probability is 50%, so the cat has a 50% chance of being alive, and an equal chance of being dead. The trick, however, is that until observed, the cat is in both states, as in, the cat is both dead and alive. The cat is in a superposition, two states at once.

This is intuitively difficult for many people, including physicists. When the cat is observed, the cat becomes either dead or alive, but not both. This is called collapsing the wave function, where observation of some form(even by a sensor) causes the superposition to resolve to one state or another.

What the researchers want to do is to cool some matter, namely a virus, down to its quantum ground state in a vacuum, until there is no subatomic activity from the virus. Then they zap the virus with a special kind of laser, which causes the virus to both be in an excited state, and a ground state, at the same time; a superposition. Having performed this same experiment with photons, electrons, and even whole molecules, they wish to see if they can make a much larger bit of matter reach a superposition. This will help show if such quantum mechanical effects apply on the macroscopic(large) scale, instead of just the microscopic scale.

The virus they need to use for the experiment needs to have several special qualities, and luckily(for our karmic revenge) the common flu virus fits this bill. In addition the tobacco mosaic virus would also be perfect for the experiment.
