Rice physicists are closing in on a method that will create a new condensed matter state in which all electrons in a material act as one by manipulating them with light and a magnetic field. This research advance technologies such as quantum computers.

For particle physicists, studying the interactions between photons and electrons has long been an area of interest. After all, observing such phenomena could eventually lead us to the creation of a viable quantum computer.

Physicist Junichiro Kono and his colleagues at Rice University are making headway on a method to create a new condensed matter state, where electrons in a material “couple” after they are manipulated with light and a magnetic field.

Meet the punk rock version of Device making via Q-Dots.

A wide range of materials can now be synthesized into semiconducting quantum dots. Because these materials grow from solutions, there is scope to combine quantum dots into devices by using simple, low-cost manufacturing processes. Kagan et al. review recent progress in tailoring and combining quantum dots to build electronic and optoelectronic devices. Because it is possible to tune the size, shape, and connectivity of each of the quantum dots, there is potential for fabricating electronic materials with properties that are not available in traditional bulk semiconductors.

Who knew that the big secret to eternal everlasting love is simply by Quantum Mechanics.

EHarmony recruits two USC data scientists to break down the hidden factors that result in long-lasting relationships.

I can honestly say that many of us working with QC hasn’t warned folks for a while on the hacking risks around QC going against even today’s most sophisticated encryption models & methods; and to be developing a strategy in how to best handle this risk. With last weeks launch by China has shown the world that we are definitely not a decade away from this risk.

Education and planning are key, cyber-security expert Tyler Cohen Wood says.

Nice.

Protein engineering techniques might one day lead to colorful ultrasound images of cells deep within our bodies.

Researchers have developed a chemical sensing material consisting of a group of carbon nanotubes individually wrapped with supramolecular polymers that can be used with a mobile phone to detect toxins.

Execellent.

Every year, humans advance climate change and global warming — and quite likely our own eventual extinction — by injecting about 30 billion tonnes of carbon dioxide into the atmosphere.

A team of scientists from the University of Toronto (U of T) believes they’ve found a way to convert all these emissions into energy-rich fuel in a carbon-neutral cycle that uses a very abundant natural resource: silicon. Silicon, readily available in sand, is the seventh most-abundant element in the universe and the second most-abundant element in the earth’s crust.

The idea of converting carbon dioxide emissions to energy isn’t new: there’s been a global race to discover a material that can efficiently convert sunlight, carbon dioxide and water or hydrogen to fuel for decades. However, the chemical stability of carbon dioxide has made it difficult to find a practical solution.
