The world’s biggest tech companies are betting big on computers that control themselves - CNN

For all their promise, quantum computers have a hard time modeling the interactions between the two families of building blocks that underlie our Universe – can you imagine a chef that struggles to describe how sugar and milk make cake? But researchers may have found a way to overcome this challenge by modeling a theoretical 'hybrid' quantum computer that promises to combine the best of both worlds. The fundamental particles that make up the cosmic cake of our existence are grouped as either fermions or bosons. In simplest terms, fermions are particles of matter, including electrons and protons, and bosons include force-mediating particles, like the photons (light) that carry the electromagnetic force.  Quantum computers are great at modeling fermions, because they're more discrete, just like the qubits that power quantum computing.

Quantum computers represent a next step in the fast-paced evolution of technology. Using quantum bits (qubits), they have the potential to run certain calculations exponentially faster than conventional computers. However, developing and fine-tuning quantum computers requires an enormous number of repetitive tests. To accelerate quantum technology development, we need a method that can read quantum states at ultrafast speeds.

A major software advance could aid the creation of bigger, more reliable quantum computers, a study suggests. Researchers have developed an algorithm that enables off-the-shelf computers to run quantum simulations previously only possible using the world's most powerful supercomputers. It means the simulations can be run using around 5% of the computing power previously needed to perform them with a supercomputer, the team says. The advance could make it cheaper and easier to run experiments vital for understanding the limitations of current quantum computers and informing the design of improved devices, experts say. Simulations confront quantum computing's limits

Author and electrician Steve McKeown wants to inspire younger generations of trades workers It was a surreal moment for Steve McKeown. His wife texted him a picture of their three children holding a copy of Lion the Electrician — a book he wrote and published himself — they found 700 kilometres away at a Coles bookstore in Sault Ste. Marie.

Trak Racer has announced its intention to enter the sim racing wheel and pedal market in 2027, with a Fanatec-based entry-level bundle. While it is not named or priced yet, expect 3Nm of force from a direct drive wheel base, a round wheel and a simple non-load-cell two-pedal set. The Australian brand was recently purchased by Corsair, the same American tech company that purchased Fanatec in 2024. In recent years, it has developed its own range of sim racing electronics, including wheel bases. These were predominantly in the upper echelons of the market, with one claiming to output 30Nm of torque, although they seemingly never went beyond the prototype stage. With Corsair owning both Trak Racer and Fanatec, it was assumed the former would focus on cockpits and seats, with the latter on wheels, pedals and electronic accessories.
