Quantum computing could revolutionize our world. For specific and crucial tasks, it promises to be exponentially faster than the zero-or-one binary technology that underlies today’s machines, from supercomputers in laboratories to smartphones in our pockets. But developing quantum computers hinges on building a stable network of qubits—or quantum bits—to store information, access it and perform computations.

Yet the qubit platforms unveiled to date have a common problem: They tend to be delicate and vulnerable to outside disturbances. Even a stray photon can cause trouble. Developing fault-tolerant qubits—which would be immune to external perturbations—could be the ultimate solution to this challenge.

A team led by scientists and engineers at the University of Washington has announced a significant advancement in this quest. In a pair of papers published June 14 in Nature and June 22 in Science, the researchers report that in experiments with flakes of semiconductor materials—each only a single layer of atoms thick—they detected signatures of “fractional quantum anomalous Hall” (FQAH) states.

Making history with 42 digits, scientists at Paderborn University and KU Leuven have unlocked a decades-old mystery of mathematics with the so-called ninth Dedekind number.

Experts worldwide have been searching for the value since 1991. The Paderborn scientists arrived at the exact sequence of numbers with the help of the Noctua supercomputer located there. The results will be presented in September at the International Workshop on Boolean Functions and their Applications (BFA) in Norway.

What started as a master’s thesis project by Lennart Van Hirtum, then a computer science student at KU Leuven and now a research associate at the University of Paderborn, has become a huge success. The scientists join an illustrious group with their work. Earlier numbers in the series were found by mathematician Richard Dedekind himself when he defined the problem in 1,897, and later by greats of early computer science such as Randolph Church and Morgan Ward. “For 32 years, the calculation of D was an open challenge, and it was questionable whether it would ever be possible to calculate this number at all,” Van Hirtum says.

Tesla says its long-awaited Dojo supercomputer, which is supposed to bring its self-driving effort to a new level, is finally going into production next month.

Dojo is Tesla’s own custom supercomputer platform built from the ground up for AI machine learning and, more specifically, for video training using the video data coming from its fleet of vehicles.

The automaker already has a large NVIDIA GPU-based supercomputer that is one of the most powerful in the world, but the new Dojo custom-built computer uses chips and an entire infrastructure designed by Tesla.

O.o!!!! Year 2022

A new photonic quantum computer takes just 36 microseconds to perform a task that would take a conventional supercomputer more than 9,000 years to complete. The new device, named Borealis, is the first quantum computer from a startup to display such “quantum advantage” over regular computers. Borealis is also the first machine capable of quantum advantage to be made available to the public over the cloud.

Quantum computers can theoretically achieve a quantum advantage that enables them to find the answers to problems no classical computers could ever solve. The more components known as qubits that a quantum computer has, the greater its computational power can grow, in an exponential fashion.

Microsoft today announced its roadmap for building its own quantum supercomputer, using the topological qubits the company’s researchers have been working on for quite a few years now. There are still plenty of intermediary milestones to be reached, but Krysta Svore, Microsoft’s VP of advanced quantum development, told us that the company believes that it will take fewer than 10 years to build a quantum supercomputer using these qubits that will be able to perform a reliable one million quantum operations per second. That’s a new measurement Microsoft is introducing as the overall industry aims to move beyond the current era of noisy intermediate-scale quantum (NISQ) computing.

We think… More.

At its Ignite conference, Microsoft today put its stake in the ground and discussed its progress in building a quantum computer and giving developers tools to experiment with this new computing paradigm on their existing machines.
