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.

Experiments with ultracold magnetic atoms reveal liquid-like quantum droplets that are 20 times larger than previously observed droplets.

Ultracold atoms can exhibit quantum behavior that mimics superfluids and superconductors. Tuning the atom-atom interactions can also reveal never-before-seen phases of matter. Following this approach, researchers working with magnetic atoms in a cigar-shaped trap have generated a single liquid-like macrodroplet, containing 20 times more atoms than in previously observed droplets. The experiment demonstrates that the stability of these droplets is due to quantum fluctuations.

When trapped atoms are cooled to near absolute zero, they form a Bose-Einstein condensate (BEC), in which their wave functions become coherent. The BEC is a macroscopic quantum object, but some of its quantum behaviors (such as quantum fluctuations) are difficult to observe because their effects are small compared to the mean-field interaction energy in this dilute system. For this reason, researchers are eager to reach parameter regimes where quantum fluctuations reveal themselves.

Microsoft says it’s doubling down on quantum computing after nabbing four top scientists who will work with a Microsoft hardware veteran to turn research into reality.

There is much to be learned from this process for other areas of technology.

Rethink electron microscopy to build quantum materials from scratch, urge Sergei V. Kalinin, Albina Borisevich and Stephen Jesse.

Quantum and Crystalize formations for data storage.

How can you store quantum information as long as possible? A team from the Vienna University of Technology is making an important step forward in the development of quantum storage.

The memory that we use today for our computers differs only between 0 and 1. However, quantum physics also allows arbitrary superimpositions of states. On this principle, the “superposition principle”, ideas for new quantum technologies are based. A key problem, however, is that such quantum-physical overlays are very short-lived. Only a tiny amount of time you can read the information from a quantum memory reliably, then it is irretrievably lost.

In 5 years if you’re looking at QC in your future state roadmap; then welcome to the dinosaur age of technology.

BEIJING: China today launched a 712-km quantum communication line, stated to be the worlds longest secure telecommunications network, which boasts of ultra-high security making it impossible to wiretap, intercept or crack the information transmitted through them.

The new quantum communication line links Hefei, capital of Anhui province, to Shanghai, the countrys financial hub.

In Brief

• Researchers have created quantum dot light-emitting diodes (LEDs) that can produce entangled photons, which could be used to encode information in quantum computing.
• As of June, the record for the most photons entangled at a time was 10. Before that, the record was eight and that could only be produced at a rate of around nine events per hour.

Researchers from the Tyndall National Institute have devised a method that would make entangling photons easier, and accelerate our journey towards the quantum computing age.

In future, greenhouse gas carbon dioxide could be removed from the atmosphere by deploying a new biological method. A team headed by Tobias Erb, Leader of a Research Group at the Max Planck Institute for Terrestrial Microbiology in Marburg, has developed a synthetic but completely biological metabolic pathway based on the model of photosynthesis that fixes carbon dioxide from the atmosphere 20% more efficiently that plants can photosynthetically. The researchers initially planned the new system, which they presented in the magazine Science this week, on the drawing board and then turned it into reality in the laboratory.

Climate change is one of the most pressing challenges of our time. The concentration of carbon dioxide (CO2) in the atmosphere owing to human activities has continually risen since the start of the Industrial Revolution. All scientific evidence indicates that this increase is exacerbating the greenhouse effect and changing the climate. The consequences are already clearly evident. To overcome the environmental as well as the social challenge of climate change, “we must find new ways of sustainably removing excessive CO2 from the atmosphere and turning it into something useful,” underlined Erb, who leads a Junior Research Group at the Max Planck Institute in Marburg.
