Physicists at the University of Bonn have cleared a further hurdle on the path to creating quantum computers: in a recent study, they present a method with which they can very quickly and precisely sort large numbers of atoms. The work has now been published in Physical Review Letters.

Imagine you are standing in a grocery store buying apple juice. Unfortunately, all of the crates are half empty because other customers have removed individual bottles at random. So you carefully fill your crate bottle by bottle. But wait: The neighboring crate is filled in exactly the opposite way! It has bottles where your crate has gaps. If you could lift these bottles in one hit and place them in your crate, it would be full straight away. You could save yourself a lot of work.

New Graphene based flash memory card coming.

Dotz Nano (ASX: DTZ) has successfully completed a proof of concept research study into the use of Graphene Quantum Dots (GQDs) in flash memory devices with the Kyung Hee University in South Korea.

GQDs are being developed for use in various applications including medical imaging, sensing, consumer electronics, energy storage, solar cells and computer storage.

In Brief:

Physicists were able to simulate high-energy experimens thanks to this primitive quantum computer. Prediction of theoretical physics may soon be tested.

Our current computers are not capable of running simulations of high-energy physics experiments. However, quite recently, scientists were able to use a primitive quantum computer in the simulation of the spontaneous creation of particle-antiparticle pairs. This makes it easier for physicists to further investigate the fundamental particles. A research team published their findings in the journal, Nature.

Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, have long required elaborate and expensive equipment to use.

Now, researchers at Princeton University have drastically shrunk much of that equipment: moving from a tabletop setup with lasers and mirrors to a pair of microchips small enough to fit on a fingertip.

In two articles recently published in the IEEE Journal of Solid State Circuits, the researchers describe one microchip that can generate terahertz waves, and a second chip that can capture and read intricate details of these waves.

With the work we are doing on cell circuitry technology and Quantum; these implants will become more and more seamless in all living things.

A biosensor developed in Clemson University, South Carolina, funded by the U.S. Department of Defense, will be able to transmit information regarding blood lactate and glucose levels of a wounded soldier or of other injured patients. The biochip will be implanted in the patient’s body for a short time and will wirelessly transmit the levels of lactate and glucose to the medical staff.

The biochip, sized 2mm x 4mm x 0.5mm, is a dual sensing element coated with hydrogels to prevent it from being rejected by human tissue. The sensor has the ability to transmit life saving readings to the medical personnel. The implantation of the chip will only be temporary, although long term biochip implants are also being tested and may be used as a precaution in some cases.

Researchers at the University of Central Florida (UCF) in the US are combining nanoscience with the principle of Faraday rotation, a magnetic phenomenon discovered in 1845, in a new method for speedy medical tests.

The team applied the magneto-optical technique, called frequency-domain Faraday rotation spectroscopy—or fd-FRS, to characterize proteins, using antibody-functionalized magnetic nanoparticles (MNPs).

Our story on QC just keeps advancing as I cannot wait to see this technology on our smart devices.

Holographic atomic memory, invented and constructed by physicists from the Faculty of Physics at the University of Warsaw, is the first device able to generate single photons on demand in groups of several dozen or more. The device, successfully demonstrated in practice, overcomes one of the fundamental obstacles towards the construction of some type of quantum computer.

Completely secure, high-speed quantum communication, or even a model of quantum computer, may be among the possible applications for the new source of single photons recently built at the Faculty of Physics at the University of Warsaw (UW Physics), Poland. An unprecedented feature of this new device is that for the first time it enables the on-demand production of a precisely controlled group of photons, as opposed to just a single one.

Off to the races again; hope folks are onboard. Quantum Bio will grow in importance; and you were warned.

Microsoft today announced that they have open sourced Bio Model Analyzer, a cloud-based tool which allows for biologists to model cell interaction and communication. This latest move is one of the many Microsoft Research initiatives which aims to help lab experts use computer science to speed up breakthroughs in cancer research and treatment.

According to the post, the Bio Model Analzyer (BMA) allows for researchers and science to compare the normal processes of healthy cells to the abnormal processes that occur when disease infects the body. Set against more traditional methods, when using computers, researchers can quickly explore many more possibilities than were previously possible. Jasmin Fisher, a Senior researcher in the programming principles and tools group in Microsoft’s Cambridge, U.K explains in the post:

In Brief

• Scientists were able to rig up a system in which they could view a “photon-blockade breakdown” where the system switched from opaque to transparent.
• This discovery has implications in both the development of advanced computer memory systems and better quantum simulations in the future.

For the first time, physicists have experimentally observed a first-order phase transition occur in a quantum system – verifying years of theoretical predictions.

Phase transitions are something that we see on a daily basis when our ice melts into water, or steam evaporates from a boiling kettle. While these transitions are easy for us to observe, phase transitions also happen on the very tiny, quantum-scale, where they play an important role in physics. But, up until now, no one had ever witnessed one experimentally.
