Blistering chip pumps 1.5 Gbps down wireless channel Japanese semiconductor group Rohm, working with Osaka University researchers, has showed off a prototype chip it says can pump an impressive 1.5 Gbps down a wireless channel using carrier frequencies in the Terahertz range. The difficult very difficult Terahertz band – frequencies between 100 GHz and 10 THz – has been the …
At those frequencies is it limited to very short range peer to peer or can they be used for WiFi like purposes?
On another note, the translation is quite impressive, guess it has a fairly regulated grammar but even so a lot better than most European Language translations that I've tried with Google (and seeing as they are supposed to use the EU parliament documents, of which there are millions you'd expect it to be a lot better)
Nothing in the quantum hardware world is fully cooked yet, but quantum computing is quite a bit further along than quantum networking – an esoteric but potentially significant technology area, particularly for ultra-secure transactions. Amazon Web Services is among those working to bring quantum connectivity from the lab to the real world.
Short of developing its own quantum processors, AWS has created an ecosystem around existing quantum devices and tools via its Braket (no, that's not a typo) service. While these bits and pieces focus on compute, the tech giant has turned its gaze to quantum networking.
Alongside its Center for Quantum Computing, which it launched in late 2021, AWS has announced the launch of its Center for Quantum Networking. The latter is grandly working to solve "fundamental scientific and engineering challenges and to develop new hardware, software, and applications for quantum networks," the internet souk declared.
Mega, the New Zealand-based file-sharing biz co-founded a decade ago by Kim Dotcom, promotes its "privacy by design" and user-controlled encryption keys to claim that data stored on Mega's servers can only be accessed by customers, even if its main system is taken over by law enforcement or others.
The design of the service, however, falls short of that promise thanks to poorly implemented encryption. Cryptography experts at ETH Zurich in Switzerland on Tuesday published a paper describing five possible attacks that can compromise the confidentiality of users' files.
The paper [PDF], titled "Mega: Malleable Encryption Goes Awry," by ETH cryptography researchers Matilda Backendal and Miro Haller, and computer science professor Kenneth Paterson, identifies "significant shortcomings in Mega’s cryptographic architecture" that allow Mega, or those able to mount a TLS MITM attack on Mega's client software, to access user files.
Sometimes it takes research to prove what was already suspected, like how utterly uncomfortable it would be to work in the metaverse.
An international team of researchers conducted a study [PDF] to just such an end, putting participants in VR headsets and taking an inventory of their self-reported physical and mental states throughout a five day, eight-hour-a-day period spent in headsets and a virtual "office".
Unlike a real job, participants were allowed to set their own work agendas and didn't perform standardized tasks yet even still had trouble undertaking these.
Video Robot boffins have revealed they've created a half-millimeter wide remote-controlled walking robot that resembles a crab, and hope it will one day perform tasks in tiny crevices.
In a paper published in the journal Science Robotics , the boffins said they had in mind applications like minimally invasive surgery or manipulation of cells or tissue in biological research.
With a round tick-like body and 10 protruding legs, the smaller-than-a-flea robot crab can bend, twist, crawl, walk, turn and even jump. The machines can move at an average speed of half their body length per second - a huge challenge at such a small scale, said the boffins.
Engineers at the University of Pennsylvania say they've developed a photonic deep neural network processor capable of analyzing billions of images every second with high accuracy using the power of light.
It might sound like science fiction or some optical engineer's fever dream, but that's exactly what researchers at the American university's School of Engineering and Applied Sciences claim to have done in an article published in the journal Nature earlier this month.
The standalone light-driven chip – this isn't another PCIe accelerator or coprocessor – handles data by simulating brain neurons that have been trained to recognize specific patterns. This is useful for a variety of applications including object detection, facial recognition, and audio transcription to name just a few.
Chinese academics have christened an ocean research vessel that has a twist: it will sail the seas with a complement of aerial and ocean-going drones and no human crew.
The Zhu Hai Yun, or Zhuhai Cloud, launched in Guangzhou after a year of construction. The 290-foot-long mothership can hit a top speed of 18 knots (about 20 miles per hour) and will carry 50 flying, surface, and submersible drones that launch and self-recover autonomously.
According to this blurb from the shipbuilder behind its construction, the Cloud will also be equipped with a variety of additional observational instruments "which can be deployed in batches in the target sea area, and carry out task-oriented adaptive networking to achieve three-dimensional view of specific targets." Most of the ship is an open deck where flying drones can land and be stored. The ship is also equipped with launch and recovery equipment for its aquatic craft.
The US Justice Department has directed prosecutors not to charge "good-faith security researchers" with violating the Computer Fraud and Abuse Act (CFAA) if their reasons for hacking are ethical — things like bug hunting, responsible vulnerability disclosure, or above-board penetration testing.
Good-faith, according to the policy [PDF], means using a computer "solely for purposes of good-faith testing, investigation, and/or correction of a security flaw or vulnerability."
Additionally, this activity must be "carried out in a manner designed to avoid any harm to individuals or the public, and where the information derived from the activity is used primarily to promote the security or safety of the class of devices, machines, or online services to which the accessed computer belongs, or those who use such devices, machines, or online services."
Video Engineers at MIT have created paper-thin speakers using a plastic film and a piezoelectric layer embossed with tiny domes.
These sheet speakers could potentially be applied to any surface for sound output or input: think surround sound or noise cancellation in aircraft. The technology also has potential for ultrasound imaging and echolocation, among other possibilities.
The work is described in a paper published recently in the journal IEEE Transactions on Industrial Electronics, "An Ultra-Thin Flexible Loudspeaker Based on a Piezoelectric Micro-Dome Array."
Researchers in the US have received a $15 million National Science Foundation (NSF) award to develop superconductor chips that ought to be much faster and use significantly less energy than the hardware the world today relies on for computing.
A team at the University of Southern California's Viterbi School of Engineering is leading the effort, and it goes by the name DISCoVER, a rather fun acronym that stands for Design and Integration of Superconductive Computation for Ventures beyond Exascale Realization.
As the name suggests, the scientists are looking to use superconducting materials as an alternative to today's semiconductors to develop new kinds of superfast and highly energy efficient integrated circuits that can enable sustainable and large-scale exascale computing.
Updated Intel and QuTech claim to have created the first silicon qubits for quantum logic gates to be made using the same manufacturing facilities that Intel employs to mass produce its processor chips.
The demonstration is described by the pair as a crucial step towards scaling to the thousands of qubits that are required for practical quantum computation.
According to Intel, its engineers working with scientists from QuTech have successfully created the first silicon qubits at scale at Intel's D1 manufacturing factory in Hillsboro, Oregon, using a 300mm wafer similar to those the company uses to mass produce processor chips.
