I'm cautiously optimistic, but I get the impression that this is another one of those "date('Y') + 1 will be the year Linux goes mainstream on desktops" situations. Quantum computers have come leaps and bounds in the past few years. Especially impressive is research into improving the signal-to-noise ratio of qubits through "dressing" them in microwaves[0]. Despite this, quantum computers still aren't, in the overwhelming majority of cases, better at solving problems than classical machines. Some work still needs to be done in terms of getting better signal-to-noise in qubits, as well as in…

arxiv link: https://arxiv.org/abs/1603.04800 Short explanation: Qubits encode information needed for quantum computers. Noise from the environment can destroy that information. By introducing a driving field to the qubit they made the qubit+driving field the new qubit ("dressed" qubit) and it was more robust to noise. It also gives some different levers to change the information (namely, the driving field).
