A team from Griffith’s Centre for Quantum Dynamics in Australia have demonstrated how to rigorously test if pairs of photons — particles of light — display Einstein’s “spooky action at a distance”, even under adverse conditions that mimic those outside the lab.

They demonstrated that the effect, also known as quantum nonlocality, can still be verified even when many of the photons are lost by absorption or scattering as they travel from source to destination through an optical fiber channel. The experimental study and techniques are published in the journal Science Advances.

Quantum nonlocality is important in the development of new global quantum information networks, which will have transmission security guaranteed by the laws of physics. These are the networks where powerful quantum computers can be linked.

The technology underpinning the new bionic hand was developed in 2014, but at the time, the equipment necessary to support it was so big the prosthetic limb could not leave the lab.

For Dennis Aabo Sorensen, who lost his hand in 2004 in a firecracker explosion, regaining the experience of touch was “fantastic.” He told CattolicaNews that “being able to feel different textures, understanding whether objects were hard or soft and how I was holding them was just incredible.”

Researchers found that Dennis was able to distinguish between a hard, soft or medium object in 78 percent of cases. In 88 percent of cases, he could correctly describe the size and shape of specific objects such as a baseball, a glass, and a tangerine. Three years later, Almerina has been given the same ability just by carrying a small computer in a backpack.

A material known as gallium nitride (GaN), poised to become the next semiconductor for power electronics, could also be essential for various space applications. Yuji Zhao, an expert in electrical and computer engineering at Arizona State University (ASU), plans to develop the first ever processor from gallium nitride, which could revolutionize future space exploration missions.

Gallium nitride is a semiconductor compound commonly used in light-emitting diodes (LEDs). The material has the ability to conduct electrons more than 1,000 times more efficiently than silicon. It outstrips silicon in speed, temperature, power handling, and is expected to replace it when silicon-based devices will reach their limits.

Besides LEDs, GaN can be used in the production of semiconductor power devices as well as RF components. Now, Yuji Zhao aims to use this material to develop a high-temperature microprocessor for space applications. He received a three-year $750,000 grant from NASA’s Hot Operating Temperature Technology (HOTTech) program for his project.

Japanese RIKEN researchers are trying to adapt existing the silicon metal–oxide–semiconductor field-effect transistors (MOSFETs) to integrate qubits with current electronics, offering the potential for scaling up quantum devices and bringing quantum computing closer to becoming a reality.

Keiji Ono and colleagues from the RIKEN Center for Emergent Matter Science and the Toshiba Corporation in Japan, in collaboration with researchers from the United States, are investigating the properties of qubits produced by imperfections or defects in silicon MOSFETs. In particular, they are exploring their potential for developing quantum computing devices that are compatible with current manufacturing technologies.

“Companies like IBM and Google are developing quantum computers that use superconductors,” explains Ono. “In contrast, we are attempting to develop a quantum computer based on the silicon manufacturing techniques currently used to make computers and smart phones. The advantage of this approach is that it can leverage existing industrial knowledge and technology.”

Biotech is one of today’s many hot frontiers of technology, but one thing holding it back is that it’s significantly less amenable to traditional computing techniques than other areas. A new startup called Asimov, spun off from research at MIT, is working on bridging the gap between the digital and the biological by creating, essentially, a set of computer-aided biology design tools. It’s a prescient enough idea that it has attracted $4.7 million in seed funding.

The problem that Asimov addresses is this. Say you’re a pharmaceutical company trying to make a tiny biocompatible machine that holds a certain amount of medication and releases it when it senses some other molecule.

In order to do so, you’d have to — well, among about a million other things — design what amounts to a logic gate and signal processor that works at the molecular scale. This is a daunting prospect, as creating molecular machinery is a labor-intensive process often involving creating thousands of variations of a given structure and testing them repeatedly to see which works.

The flip side is there’s only a tiny storage density improvement in play here; Toshiba is using 1.56TB platters, while its competitors are back on ~1.5TB. Shoving more platters into a drive while retaining a 3.5-inch form factor is mechanically impossible after a certain point. And while hydrogen gas is only about half as dense as helium, that’s still a much smaller improvement than what helium offered compared with Earth’s atmosphere.

The MG07ACA14TE (14TB) and the MG07ACA12TE (12TB) are both 7200 RPM drives with SATA 6G support. The 14TB drive is rated for 260MB/s of sequential read performance, while the 12TB drive is rated for 250MB/s. Toshiba has talked about a 16TB drive, according to Anandtech, but that much space would require roughly 1.8TB platters, a significant jump over what the company is using today.

Seagate has pledged to bring the next leap in recording technology, Heat-Assisted Magnetic Recording (HAMR) to market, alongside helium-filled drives of at least 18TB. Those drives could be on the market as soon as 2018. Western Digital is backing a technology known as MAMR (Microwave-Assisted Magnetic Recording), in which microwave fields emitted by a spin-torque oscillator allows drives to use weaker magnetic fields when writing data. This is supposed to boost densities up to 4.5Tbits/inch over time, which would theoretically enable 40TB hard drives, eventually. MAMR may be ready by 2019, though all timelines should be taken provisionally; some of these technologies have been in the works for a decade or more.

Practical quantum computing has been big news this year, with significant advances being made on theoretical and technical frontiers.

Some of the earliest computers relied upon tape drives for storage, but we’ve since moved on to faster and more versatile storage technologies. Still, tape drives continue to exist in enterprise, and they’ve been advancing by leaps and bounds while you haven’t been paying attention. IBM just announced a new record in data storage density — 201 gigabits per square inch on a magnetic tape (that’s one square inch of it above). That works out to a whopping 330TB of uncompressed data on a single tape drive cartridge.

IBM reached this plateau in magnetic tape density by developing several new technologies. Older versions of IBM’s magnetic tape used a thin film of barium ferrite particles applied to the surface like paint. “Sputtered tape” uses several layers of thin metal film that are applied using a new vacuum technology. A layer of lubricant is also applied to the reading surface of the tape to keep the tape in good working order as it’s run through the drive. The higher density arrangement of magnetic nanoparticles will, of course, require new drive technology to read.
