Submission Quantum measurements leave Schrödinger's cat alive->

Walking The Walk writes: Your co-workers who keep using Schrödinger's cat metaphor may need to find a new one. New Scientist reports that

by making constant but weak measurements of a quantum system, physicists have managed to probe a delicate quantum state without destroying it – the equivalent of taking a peek at Schrodinger's metaphorical cat without killing it. The result should make it easier to handle systems such as quantum computers that exploit the exotic properties of the quantum world.

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
