Nice update and glad the author mentioned Airbus, Gooch and Housego as I often see these 2 contributors missed in QC roadmap and companies engaged on QC activities. Airbus has been heavily involved with QC research and development for a few years now.

How can quantum information be stored as long as possible? An important step forward in the development of quantum memories has been achieved by a research team of TU Wien.
Conventional memories used in today’s computers only differentiate between the bit values 0 and 1. In quantum physics, however, arbitrary superpositions of these two states are possible. Most of the ideas for new quantum technology devices rely on this “Superposition Principle.” One of the main challenges in using such states is that they are usually short-lived. Only for a short period of time can information be read out of quantum memories reliably, after that it is irrecoverable.
A research team at TU Wien has now taken an important step forward in the development of new quantum storage concepts. In cooperation with the Japanese telecommunication giant NTT, the Viennese researchers lead by Johannes Majer are working on quantum memories based on nitrogen atoms and microwaves. The nitrogen atoms have slightly different properties, which quickly leads to the loss of the quantum state. By specifically changing a small portion of the atoms, one can bring the remaining atoms into a new quantum state, with a lifetime enhancement of more than a factor of ten. These results have now been published in the journal “Nature Photonics.”
I believe we’re really looking at less than 10yrs given the speed of evolution of QC to date. Instead of two new QC discoveries each year to advance QC; we’re now seeing 2 new discoveries every 2 months now not to mention China and US advancements on networking and communications and scalable QC for devices which Google plans to release their QC device in 2017.
Quantum computers could bring about a quantum leap in processing power, with countless benefits for fields like data science and AI. But there’s also a dark side: this extra power will make it simple to crack the encryption keeping everything from our emails to our online banking secure.
A recent report from the Global Risk Institute predicted that there is a one in seven chance vital cryptography tools will be rendered useless by 2026, rising to a 50% chance by 2031. In the meantime, hackers and spies can hoover up data encrypted using current approaches and simply wait until quantum computers powerful enough to crack the code have been developed.

Physicists at the University of Bath have developed a technique to more reliably produce single photons that can be imprinted with quantum information.
The invention will benefit a variety of processes which rely on photons to carry quantum information, such as quantum computing, secure quantum communication and precision measurements at low light levels.
Photons, particles of light, can be imprinted with information to be used for things like carrying out calculations and transmitting messages. To do this you need to create individual photons, which is a complicated and difficult process.
Any technology with the word “quantum” in the name is by nature impossible for lay people to understand and even difficult for scientists to get their arms fully around. However, though its workings are mysterious, quantum science offers very useful everyday tools.
There has been a race for quantum computing for years. Part of the reason is that these devices will leave today’s computers in the dust. The other element is that planners see that current computing technology is reaching its growth limits. Quantum computing is the key to the future to them, not science fiction.
Microsoft, which Computerworld says has been researching quantum computing for more than a decade, is expanding its quantum computing efforts. It has put Todd Holmdahl, one of the people involved in the development of Kinect, HoloLens and Xbox, in charge of developing quantum hardware and software. It’s also hired professors from the Delft University of Technology in the Netherlands; the University of Copenhagen; ETH Zurich and University of Sydney in Australia.
DAILY VIDEO: Microsoft Starts Quantum Computer Development Program; Cerber Ransomware Expands Database Encryption Attacks; IBM Debuts Watson Internet of Things Services Practice; and there’s more.
Today’s topics include Microsoft’s plan to build a Quantum computer, Trend Micro’s find that the Cerber malware is seeking out database files to encrypt and hold for ransom, IBM’s new Watson internet of things services for the automotive, electronics and insurance industries, and the release of the Microsoft Office Online Server update.
Microsoft is on a mission to build a quantum computer, and the company has appointed Todd Holmdahl to manage the project. Holmdahl is the corporate vice president of Microsoft Quantum, a unit dedicated to turning the company’s quantum computing research into real-world products.

How does one prevent hacking from a QC system? Easy, on board to QC first before others do.
Quantum computers have the potential to perform calculations faster than ever possible before, inviting a significant rethink in how we approach cyber security.
Given the amount of research being ploughed into this area, we are likely to see a commercially viable machine in the near future, so cryptographers and the cyber security industry in general should work to have a clear view on the implications way ahead of that achievement.

The mere mention of “quantum consciousness” makes most physicists cringe, as the phrase seems to evoke the vague, insipid musings of a New Age guru. But if a new hypothesis proves to be correct, quantum effects might indeed play some role in human cognition. Matthew Fisher, a physicist at the University of California, Santa Barbara, raised eyebrows late last year when he published a paper in Annals of Physics proposing that the nuclear spins of phosphorus atoms could serve as rudimentary “qubits” in the brain — which would essentially enable the brain to function like a quantum computer.
Isher’s hypothesis faces the same daunting obstacle that has plagued microtubules: a phenomenon called quantum decoherence. To build an operating quantum computer, you need to connect qubits — quantum bits of information — in a process called entanglement. But entangled qubits exist in a fragile state. They must be carefully shielded from any noise in the surrounding environment. Just one photon bumping into your qubit would be enough to make the entire system “decohere,” destroying the entanglement and wiping out the quantum properties of the system. It’s challenging enough to do quantum processing in a carefully controlled laboratory environment, never mind the warm, wet, complicated mess that is human biology, where maintaining coherence for sufficiently long periods of time is well nigh impossible.

Microsoft is accelerating its efforts to make a quantum computer as it looks to a future of computing beyond today’s PCs and servers.
Microsoft has researched quantum computing for more than a decade. Now the company’s goal is to put the theory to work and create actual hardware and software.
To that effect, Microsoft has put Todd Holmdahl—who was involved in the development of Kinect, HoloLens, and Xbox—to lead the effort to create quantum hardware and software. The company has also hired four prominent university professors to contribute to the company’s research.
