Austrian physicists have developed a new architecture for universal quantum computers

Austrian physicists have developed a new architecture for building universal quantum computers, which reduces the number of physical qubits for calculating complex mathematical problems. This was reported by the press service of the University of Innsbruck.

Austrian physicists have developed a new architecture for universal quantum computers

This architecture was originally designed to solve optimization problems. In the process of its creation, we simplified it as much as possible in order to solve problems as quickly as possible. For example, in our system, physical qubits encode not single bits of data, but the relative distance between them. This saves us from the problem of interaction between all memory cells.“, – said Professor of the University of Innsbruck (Austria) Wolfgang Lechner.

Quantum computers are called special computing devices, whose power is growing very quickly due to the application of the principles of quantum mechanics in their work. They consist of so-called qubits – memory cells and primitive computing modules capable of storing both zero and one at the same time.

As a rule, qubits can be in this state for an extremely limited time, since random interactions with objects of the surrounding world can destroy the quantum state in which they are located and break the bonds that unite them with neighboring quantum memory cells. This is one of the main obstacles to the creation of complex computers containing several hundred or thousands of qubits of any type.

Professor Lechner and his colleagues have developed an unusual approach that solves this problem with a new architecture for building universal quantum computers. By the last word, scientists mean quantum computers that carry out calculations according to the same logical principles as conventional computers.

Austrian physicists discovered that such computing systems can be built on the basis of the mathematical parity principle, according to which most of the physical qubits of the system encode not logical bits, but a checksum, a kind of distance between neighboring information cells. This allows some types of two-qubit logical operations to be performed on a single physical qubit, and also protects memory cells from interference.

This can be implemented on any physical quantum computer, including machines based on ions, superconductors, photons, and cold atoms. In accordance with the calculations of scientists, the approach they created will significantly speed up many complex quantum calculations, including Fourier transforms and breaking ciphers using the Shor algorithm.

According to the researchers, they are already working on bringing this architecture to life on an experimental quantum computer, which is being developed at the University of Innsbruck. Successful testing of this approach for quantum computing will expand the scope of practical applicability of already existing multi-qubit systems, the scientists concluded.

Named the best apps and games for iPhone iPad Mac

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

Named the best apps and games for iPhone, iPad, Mac, Apple TV and Apple Watch

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.

Former president of Neuralink launched a startup to develop a

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.
