Scientists have demonstrated a unique phase of matter

Posted by in categories: particle physics, quantum physics

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: the atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.$$!ad_code_content_spilt_video_ad!$$” Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the fascinating experiment. In the laboratory, her team observed how macrodroplets formed in a quantum gas.

New Theory Shows Interaction Between Parallel Worlds And The Potential To Rewrite Quantum Theory

Posted by in categories: cosmology, quantum physics

The 20th century was loaded with experiments and discoveries that I sometimes forget how big of an impact things like quantum theory really had on our lives. Bold new thought experiments and suggestions have been made that seemingly left us wondering what our universe might be made of after all.

Quantum technology 2.0

Posted by in categories: quantum physics, transportation

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.

New quantum states for better quantum memories

Posted by in categories: computing, particle physics, quantum physics

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.”

Quantum Computers Could Crush Today’s Top Encryption in 15 Years

Posted by in categories: encryption, finance, quantum physics, robotics/AI

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.

More reliable way to produce single photons

Posted by in categories: computing, particle physics, quantum physics

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.

The Dangers of Quantum Computing

Posted by in categories: augmented reality, computing, quantum physics

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.

How will quantum computing impact security processes?

Posted by in categories: cybercrime/malcode, encryption, mobile phones, quantum physics

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.
