Releases free preview of Quantum Development Kit

Posted by in categories: computing, quantum physics

So you want to learn how to program a quantum computer. Now, there’s a toolkit for that.

Microsoft is releasing a free preview version of its Quantum Development Kit, which includes the Q# programming language, a quantum computing simulator and other resources for people who want to start writing applications for a quantum computer. The Q# programming language was built from the ground up specifically for quantum computing.

Optically tunable microwave antennas for 5G applications

Posted by in categories: computing, engineering, internet

Multiband tunable antennas are a critical part of many communication and radar systems. New research by engineers at the University of Bristol has shown significant advances in antennas by using optically induced plasmas in silicon to tune both radiation patterns and operation frequency.

Conventional antenna tuning is performed with diodes or Micro-Electro-Mechanical Systems (MEMS) switches. However, these approaches have significant drawbacks as systems become more complex and move to higher frequencies, which is anticipated for 5G systems.

The first paper, published in IET Optoelectronics, co-authored by Dr Chris Gamlath, Research Associate in RF Engineering during his PhD, shows how a silicon superstrate placed over a slotted microstrip patch can be used to tune radiation patterns.

This Was the Portable Hard Drive of 1985—Clocking In at 20MB

Posted by in categories: computing, habitats

Portable hard drives seem like they’re bound to go way of the dinosaur, thanks to the rise of services like Dropbox and Google Drive. But if you wanted to take a large file home with you back in 1985, you didn’t have quite so many options. Your best bet? Maybe this hard drive from Maynard.

“Leave the computer, take the drive!” the ad said in big, bold letters in the July 1985 issue of Byte magazine. And look at just how portable that thing is!

Physicists Just Invented an Essential Component Needed For Quantum Computers

Posted by in categories: computing, quantum physics

In 2016, the Nobel Prize in Physics went to three British scientists for their work on superconductors and superfluids, which included the explanation of a rather odd phase of matter.

Now, for the first time, their discovery has a practical application – shrinking an electrical component to a size that will help quantum computers reach a scale that just might make them useful.

In a collaboration with Stanford University in the US, a team of scientists from the University of Sydney and Microsoft have used the newly found phase of matter — topological insulator — in shrinking an electrical component called a circulator 1,000 times smaller.

Is quantum artificial life possible?

Posted by in categories: biological, computing, quantum physics


Physicists in the QUTIS Quantum Biomimetics and Quantum Artificial Life research group at the Department of Physical Chemistry, University of the Basque Country in Spain have harnessed the unprecedented power of the IBM Q Cloud Quantum Computer —recently made available for public use ( IBM makes 20 qubit quantum computing machine available as a cloud service) —to reproduce the hallmark features of Darwinian life and evolution in microscopic quantum systems, proving they can efficiently encode quantum features and biological behaviors that are usually associated with living systems and natural selection.

The SMS text message turns 25 today

Posted by in category: computing

There weren’t too many historical events on December 3, 1992, but the date is an important one for mobile fans: 25 years ago today, the very first text message was sent. It simply read, “Merry Christmas”

On the same day that Whitney Houston’s I will always love you was the number 1 song in the US and Home Alone 2 topped the box office, 22-year-old Sema Group software architect Neil Papworth sent the first SMS (Short Message Service).

It was sent over the Vodafone GSM network in the UK, though back then handsets could only receive messages, not send them. Papworth sent it to an Orbitel 901 handset belonging to the then-director of Vodafone, Richard Jarvis, using a computer.

Undoing Aging with Molecular and Cellular Damage Repair

Posted by in categories: bioengineering, biotech/medical, computing, life extension

Dr. Aubrey de Grey Summarizes Rejuvenation Research at the MIT Technology Review. To learn more about the work of Dr. Aubrey de Grey and the SENS Foundation visit http://www.sens.org/

Since the dawn of medicine, aging has been doctors’ foremost challenge. Three unsuccessful approaches to conquering it have failed: treating components of age-related ill health as curable diseases, extrapolating from differences between species in the rate of aging, and emulating the life extension that famine elicits in short-lived species. SENS Research Foundation is spearheading the fourth age of anti-aging research: the repair of age-related damage, that is, rejuvenation biotechnology.

The Strategies for Engineered Negligible Senescence (SENS) approach was first proposed in 2002. “Senescence,” here, refers to the actuarial phenomenon—the trend that individuals within a population suffer from an increasing morbidity and mortality rate in (typically exponential) relation to their chronological age. “Negligible” is used in a statistical sense: we consider a level of senescence negligible if no age-related contribution to mortality is statistically demonstrable within a population, given the “background noise” of age-independent mortality (such as unfortunate encounters with motor vehicles). Finally, by “Engineered,” we indicate that this state is achieved by the deliberate application of biomedical therapies, and is not the normal situation. The goal of SENSE is thus unambiguously defined; we seek methods to convert a population experiencing a non-negligible level of senescence into one experiencing a negligible level.

Physicists set new record with 10-qubit entanglement

Posted by in categories: computing, quantum physics

(Phys.org)—Physicists have experimentally demonstrated quantum entanglement with 10 qubits on a superconducting circuit, surpassing the previous record of nine entangled superconducting qubits. The 10-qubit state is the largest multiqubit entangled state created in any solid-state system and represents a step toward realizing large-scale quantum computing.

Lead researcher Jian-Wei Pan and co-workers at the University of Science and Technology of China, Zhejiang University, Fuzhou University, and the Institute of Physics, China, have published a paper on their results in a recent issue of Physical Review Letters.

In general, one of the biggest challenges to scaling up multiqubit entanglement is addressing the catastrophic effects of decoherence. One strategy is to use superconducting circuits, which operate at very cold temperatures and consequently have longer coherence times.
