Single-atom Laser Built at Caltech

Posted by Hemos on from the one-atom-long dept.

hweimer writes "A research group at Caltech has successfully constructed a laser consisting of only one caesium atom. The emitted light is very weak but highly ordered, so such a device may be used to control a quantum computer. More on this can be found at PhysicsWeb."

    Easy. Just mount a low-intensity x-ray (or similar hard radiation) laser on each shotgun pellet, arrange them in a nice spherical shell around the patient, all pointing towards the centre, and make sure the tumour is right at the centre of the shell. All the low, harmless intensities will add up to some real stuff in the middle et voila! Radiation therapy with a shotgun!
