Physicists challenge classical world with quantum-mechanical implementation of 'shell game'

Physicists challenge classical world with quantum-mechanical implementation of 'shell game': "The researchers fabricated a chip where three resonators of a few millimeters in length are coupled to two qubits. 'The architecture studied in this work resembles a quantum railroad,' said Mariantoni. 'Two quantum stations –– two of the three resonators –– are interconnected through the third resonator which acts as a quantum bus. The qubits control the traffic and allow the shuffling of photons among the resonators.'"
