There seems to be continuous progress toward sufficiently interesting
quantum computers.

Cost and rarity will keep these out of the hands of petty
criminals for a while but nations will want them if only
to be members of the "club".

QR (quantum resistant) encryption seems to be needed sooner not later
than I would have expected.

"An international team, led by a scientist from the University of Sussex,
have today unveiled the first practical blueprint for how to build a
quantum computer, the most powerful computer on Earth.

This huge leap forward towards creating a universal quantum computer is
published today (1 February 2017) in the influential journal *Science
Advances <http://advances.sciencemag.org/content/3/2/e1601540>*.

"It has long been known that such a computer would revolutionise industry,
science and commerce on a similar scale as the invention of ordinary
computers. But this new work features the actual industrial blueprint to
construct such a large-scale machine, more powerful in solving certain
problems than any computer ever constructed before. "
