Unitary collapse of Schrödinger's cat state
The authors study a system composed of a single qubit coupled to a soft-mode quantum oscillator. They show that spontaneous unitary evolution of this system create a Schr"odinger-cat-like state of the oscillator, which is subsequently lost in a sudden process strongly resembling the measurement-induced collapse of wave function.
