"We show that optical bias fields injected into multistable #optical systems enable a controllable source of #quantum #randomness, and we demonstrated this concept in an optical parametric oscillator (OPO). By injecting bias pulses with less than one #photon on average, we controlled the probabilities of the two possible OPO output states."

Perhaps the whole #Universe is the result of a #vacuumfluctuation, originating from what we could call #quantumnothingness.
