Scientists have found a way to “photograph” electrons in motion “at a high frame rate.” This was reported by the publication New Atlas.
The frequency of modern processes is measured in billions of hertz – that is, the state of the system changes billions of times per second. “For quantum computing, this is very slow because the electrons inside a computer chip collide trillions of times per second, and each collision completes a cycle of quantum computing. To improve performance, we need snapshots of the movement of electrons that are a billion times faster. And now we have them,” said McKillo Kira of the University of Michigan, one of the authors of the paper.
The team’s new device takes measurements on a completely different time scale – attoseconds (10-eighteen), which is one quintillionth of a second.
To achieve this, scientists use two light pulses with a specific energy. The first pulse of infrared light puts the electrons in a state where they can move through the semiconductor material. A low-energy terahertz pulse is then applied, which directs the electrons into trajectories that cause head-on collisions. This produces a flash of light, and the exact timing of these flashes can be determined to reveal quantum interactions and other information. Scientists can then reconstruct the picture of events, as if by obtaining “photos” of the system at each moment of time with an interval of attoseconds.
Physicists say such devices are the first step towards improving quantum computers, as they expand our understanding of how electrons move, behave and interact in materials.
Named the best apps and games for iPhone, iPad, Mac, Apple TV and Apple Watch
Apple has announced the winners of the annual App Store Awards, naming the 16 best apps and games presented in the App Store in 2022.
This year’s winners represent a diverse community of developers from around the world whose apps and games have been selected by the Apple App Store editorial team for “exceptional experiences and deep cultural impact.”
This year’s App Store Award winners have reimagined our app experience with a fresh and thoughtful perspective. From self-taught soloists to international teams operating around the world, these entrepreneurs make a significant impact and represent how apps and games affect our communities and lives.
Tim Cook, Apple CEO
iPhone App of the Year is BeReal, which lets you share photos and chat with friends. It does not have filters and masks, so the pictures are as vivid as possible, close to reality. Apex Legends Mobile was named the best game for iPhone.
The iPad App of the Year was GoodNotes 5 by Time Base Technology Limited, which “takes digital note-taking to the next level with best-in-class Apple Pencil support.”
For Mac computers, MacFamilyTree 10 was the best app, which will be appreciated by genealogists, and for Apple Watch smartwatches, the Gentler Streak app was chosen.
You can see the full list of applications, including eight games, on the Apple website.
Recall that the former top manager criticized the App Store in a recent article.
ECSIPC Unveils LEET Z790H7-A Motherboard and LEET B660 Barebone Computer
ECS Industrial Computer, also known as ECSIPC, is a subsidiary of leading motherboard and computer manufacturer Elitegroup Computer Systems (ECS). ECSIPC has joined forces with Intel with the introduction of the LEET Z790H7-A motherboard and the LEET B660 barebones gaming computer.
The Z790H7-A motherboard provides excellent performance for gamers and professionals. It is compatible with 12th and 13th generation Intel Core processors (Raptor Lake-S and Alder Lake-S) and also supports Windows 11 64-bit.
The Intel Z790 chipset has improved the overclocking function, it also supports DDR5 and PCIe5 RAM. DDR5 delivers 50% higher throughput than DDR4, while PCIe 5.0 increases TPS from 16 GT/s (with PCIe 4.0) to 32 GT/s.
The Z790H7-A is equipped with 4 M.2 SSD slots. The motherboard is equipped with a USB 3.2 Gen2x2 Type-C (20 Gb / s) port, in particular, for external storage devices. The Z790H7-A motherboard is equipped with an 18-phase digital power supply. In terms of Internet support, the motherboard is equipped with an Intel 2.5G LAN connector and supports M.2 2230 802.11ax wireless communication.
The Z790H7-A motherboard uses one-click BIOS update, which makes it easy for ordinary users. The Z790H7-A motherboard boasts individual adjustable LEDs and an 8-channel ALC1220 audio chip with Japanese capacitors.
The LEET B660 barebone computer supports 12th generation Intel processors (Core i3, i5, i7 and i9). LEET B660 can be equipped with two graphics cards. In particular, the manufacturer offers versions with NVIDIA Nvidia RTX 3070/3060 Ti video cards, as well as AMD Radeon RX 6650 XT.
The computer received an ECS B660H7-M20 motherboard based on the Intel B660 chipset. It supports up to 64 GB of RAM, and the power supply has a power of 550 or 650 W, depending on the version.
LEET B660 is equipped with clear tempered glass side panels that can be easily opened without tools. The LEET B660 has plenty of room for airflow with large air intakes.
The PC itself is equipped with hard drive slots and supports up to three 2.5″ drives or one 3.5″ hard drive. In addition, the LEET B660 has multiple lighting modes including static, breathing and color cycle.
Former president of Neuralink launched a startup to develop a brain-computer interface without implants
A startup Hodak Science has been launched in the United States, where they are developing a brain-computer interface. At the same time, the Hodak Science version does not require implants. Its creator is the former president of Neuralink, Max Hodak.
For work, it is proposed to use not electronics, but photonics; for manipulations with the brain, it is proposed to use light. The startup has already received funding of $160 million. At the moment, the company has already developed the Science Eye prosthesis, which is being tested on rabbits, and will move to human trials in the coming years. It should help with the treatment of certain diseases of the central and peripheral vision.
Hodak Science also wants to create an operating system that will output data directly to the retina, which will allow you to show hints, instructions, and so on. So far, it has not been reported when it is worth waiting for ready-made solutions, but the operation itself has already been worked out. True, this requires stimulating the cells of the optic nerve, for this they are injected with an artificial protein.
At the same time, Hodak remains a shareholder of Neuralink, as well as a holder of securities in a competing startup, Synchron. These companies are developing implantable chips.
