Remotely Prepared Quantum States (image) University of Vienna Caption This is a graphic representation of remotely prepared quantum states. In their experiment, the researchers demonstrated that it is possible to prepare quantum states remotely by means of quantum discord (outside the circle) which might not always be possible to achieve by means of entanglement (inside the circle).
