Analysts at Booz Allen Hamilton warn that Chinese espionage efforts could soon focus on encrypted data.
This entrepreneurs immigrant parents instilled self-sufficiency. Now, he’s taking on tech giants like Apple and Microsoft by engineering a laptop anyone can build and repair on their own.
According to reports, Samsung will increase the proportion of Exynos chips used in its own models in 2022 to reduce its dependence on Qualcomm chips. Samsung’s use of Exynos chips in its own models will increase by about 2–3 times next year. At the same time, Samsung has set a sales target of 300 million mobile phones next year.
Industry insiders pointed out that Samsung is vigorously supporting Exynos chips. On the one hand, it will increase the proportion of Exynos chips in its own models. On the other hand, it is open to partners. Recall that the company co-developed the Exynos 1,080 chip with Vivo which the latter used in the Vivo X60 series.
Today’s quantum computers are complicated to build, difficult to scale up, and require temperatures colder than interstellar space to operate. These challenges have led researchers to explore the possibility of building quantum computers that work using photons—particles of light. Photons can easily carry information from one place to another, and photonic quantum computers can operate at room temperature, so this approach is promising. However, although people have successfully created individual quantum “logic gates” for photons, it’s challenging to construct large numbers of gates and connect them in a reliable fashion to perform complex calculations.
Now, Stanford University researchers have proposed a simpler design for photonic quantum computers using readily available components, according to a paper published Nov. 29 in Optica. Their proposed design uses a laser to manipulate a single atom that in turn, can modify the state of the photons via a phenomenon called “quantum teleportation.” The atom can be reset and reused for many quantum gates, eliminating the need to build multiple distinct physical gates, vastly reducing the complexity of building a quantum computer.
“Normally, if you wanted to build this type of quantum computer, you’d have to take potentially thousands of quantum emitters, make them all perfectly indistinguishable, and then integrate them into a giant photonic circuit,” said Ben Bartlett, a Ph.D. candidate in applied physics and lead author of the paper. “Whereas with this design, we only need a handful of relatively simple components, and the size of the machine doesn’t increase with the size of the quantum program you want to run.”
On-chip frequency shifters in the gigahertz range could be used in next generation quantum computers and networks.
The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks and computers, will require even more control over the properties of a photon.
One of the hardest properties to change is a photon’s color, otherwise known as its frequency, because changing the frequency of a photon means changing its energy.
In a recently published white paper, imec provided an overview of the building blocks for the next generation of medical implants. Integrating the building blocks into smart chips provides a comprehensive solution that is smaller, smarter and more connected.
MS say that Malaysian semiconductor fabrication plants are back to 100%. auto chip shortage is now in the rear-view mirror I hope they are correct. I’d like to hear it from auto producers too though. Toyota, at least, is upbeat though:
With feature updates galore, paradigm-changing DDR5 memory, and much more, the technology backing Intel’s 12th Generation Core CPUs is just as interesting as the chips themselves. We’ve got a breakdown.
Physicists have created a new ultra-thin two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a new platform for quantum computing and advance research into unconventional superconductivity and quantum criticality.
The researchers showed that by starting from seemingly common materials, a radically new quantum state of matter can appear. The discovery emerged from their efforts to create a quantum spin liquid which they could use to investigate emergent quantum phenomena such as gauge theory. This involves fabricating a single layer of atomically thin tantalum disulfide, but the process also creates islands that consist of two layers.
