Some good news: two new papers from my lab (I am an author on both) will appear in the September 20th and 27th issues of Nature. In the September 20th paper we demonstrate a device which produces single microwave photons on-demand. The September 27th paper shows multiplexed read-out and control of two qubits coupled by a quantum bus. We also take some steps toward a two-qubit gate.
It is kind of funny that these papers will appear nearly simultaneously since the photon on-demand paper was submitted 5-6 months earlier.
