IBM has also received more funding [newscientist.com] to pursue universal quantum computing:

The race to build a full-blown quantum computer is heating up. Tech giant IBM has been working on error-correcting techniques for quantum hardware, and has now won funding from the US Intelligence Advanced Research Projects Activity (IARPA) to take it to the next level.

[...] Chow says they need around 20 physical qubits to create one logical qubit, but packing the qubits close together will be tricky. "When you put many of them together, you don't know that they are going to work the same way as when you just have one," he says. "How you properly engineer this larger chip is going to be a big challenge."

IBM and IARPA have not yet revealed how much funding is going into the five-year research programme, but money is already pouring into quantum computing around the world.
