If you have trouble wrapping your mind around quantum physics, don’t worry — it’s even hard for supercomputers. The solution, according to researchers from Google, Harvard, Lawrence Berkeley National Laboratories and others? Why, use a quantum computer, of course. The team accurately predicted chemical reaction rates using a supercooled quantum circuit, a result that could lead to improved solar cells, batteries, flexible electronics and much more.

Chemical reactions are inherently quantum themselves — the team actually used a quote from Richard Feynman saying “nature isn’t classical, dammit.” The problem is that “molecular systems form highly entangled quantum superposition states, which require many classical computing resources in order to represent sufficiently high precision,” according to the Google Research blog. Computing the lowest energy state for propane, a relatively simple molecule, takes around ten days, for instance. That figure is required in order to get the reaction rate.

Luv it; more believers.

Quantum computers promise to enable faster, far more complex calculations than today’s silicon chip-based computers. But they also raise the possibility that future computers could retroactively break the security of any digital communications that exist today, which is why Google is experimenting with something called “post-quantum cryptography.”

While quantum computer development remains in its early stages, some such computers are already in operation. In theory, future generations of quantum computers could “decrypt any Internet communication that was recorded today, and many types of information need to remain confidential for decades,” software engineer Matt Braithwaite wrote yesterday in a post on Google’s security blog. “Thus even the possibility of a future quantum computer is something that we should be thinking about today.”

I shared this yesterday; however, another article with another spin (no pun intended)

Working at the Massachusetts Institute of Technology’s (MIT) Fermilab physics laboratory in Illinois, a team of physicists studied the states of neutrinos, among the smallest components of an atom.

Interesting study occurring on subatomic particles (aka neutrinos) in how they can be in superposition, without individual identities, when traveling hundreds of miles.

Now, MIT physicists have found that subatomic particles called neutrinos can be in superposition, without individual identities, when traveling hundreds of miles. Their results, to be published later this month in Physical Review Letters, represent the longest distance over which quantum mechanics has been tested to date.

By narrowing the bandgap of titania and graphene quantum dots.

Researchers have found a method of harvesting light.

Griffith University researchers have discovered significant new potentials for light harvesting through narrowing the bandgap of titania and graphene quantum dots.

Until quite recently, creating a hologram of a single photon was believed to be impossible due to fundamental laws of physics. However, scientists at the Faculty of Physics, University of Warsaw, have successfully applied concepts of classical holography to the world of quantum phenomena. A new measurement technique has enabled them to register the first ever hologram of a single light particle, thereby shedding new light on the foundations of quantum mechanics.

Scientists at the Faculty of Physics, University of Warsaw, have created the first ever hologram of a single light particle. The spectacular experiment, reported in the journal Nature Photonics, was conducted by Dr. Radoslaw Chrapkiewicz and Michal Jachura under the supervision of Dr. Wojciech Wasilewski and Prof. Konrad Banaszek. Their successful registering of the hologram of a single photon heralds a new era in holography: quantum holography, which promises to offer a whole new perspective on quantum phenomena.

“We performed a relatively simple experiment to measure and view something incredibly difficult to observe: the shape of wavefronts of a single photon,” says Dr. Chrapkiewicz.

This truly makes QC more practical on many fronts. First, no need for QC to reside in an “icebox” room/ environment. Second, with the recent findings on making quantum computing scalable; we now have a method in place to not make QC devices over heat as well. So, again another major step forward by Sydney and their partners in Switzerland and Germany.

A group of international researchers, including a leading research from the University of Sydney, has made a breakthrough discovery, making a conducting carbon material that they demonstrated could be used to perform quantum computing at room temperature, rather than near absolute zero (−273°C).

Few of us really understand the weird world of quantum physics – but our bodies might take advantage of quantum properties.

A team of researchers has overcome a key challenge — how to build a quantum computer that is capable of functioning at room temperature.
