Quantum computing is one of those technologies which will be widely put to use before we actually understand well how it's working - I'm hoping that the surprises that come as a result of using it without fulling comprehending how it works, will not be too nasty….

Giant step forward taken in generating optical qubits
The optical chip overcomes a number of obstacles in the development of quantum computers. A research team has demonstrated that on-chip quantum frequency combs can be used to simultaneously generate multiphoton entangled quantum bit states. It is the first chip capable of simultaneously generating multi-photon qubit states and two-photon entangled states on hundreds of frequency modes. The chip is scalable, compact, and compatible with existing technologies. Ref. Source 2q.
World-first pinpointing of atoms at work for quantum computers
Scientists can now identify the exact location of a single atom in a silicon crystal, a discovery that is key for greater accuracy in the operation of tomorrow's silicon based quantum computers. Ref. Source 1t.
Quantum computers will definitely change how the world is going to use their technology soon. With the great accuracy granted, the electronic devices can work a lot faster which can bring out a whole new level of enjoyment as well as making the workforce easier for everyone.
Protecting quantum computing networks against hacking threats
As we saw during the 2016 US election, protecting traditional computer systems, which use zeros and ones, from hackers is not a perfect science. Now consider the complex world of quantum computing, where bits of information can simultaneously hold multiple states beyond zero and one, and the potential threats become even trickier to tackle. Researchers have uncovered clues that could help administrators protect quantum computing networks from external attacks. Ref. Source 3p.
Error-free into the quantum computer age. Ion-trap technologies available today are suitable for building large-scale quantum computers, research shows. Scientists have introduced trapped-ion quantum error correction protocols that detect and correct processing errors. Source 7d.
