Quantum computing systems have the potential to outperform classical computers on some tasks, helping to solve complex real-world problems in shorter times. Research teams worldwide have thus been trying to realize this quantum advantage over traditional computers, by creating and testing different quantum systems.

Researchers at Tsinghua University recently developed a new programmable quantum phononic processor with trapped ions. This processor, introduced in a paper in Nature Physics, could be easier to scale up in size than other previously proposed photonic quantum processors, which could ultimately enable better performances on complex problems.

“Originally, we were interested in the proposal of Scott Aaronson and others about Boson sampling, which might show the quantum advantages of simple linear optics and photons,” Kihwan Kim, one of the researchers who carried out the study, told Phys.org. “We were wondering if it is possible to realize it with the phonons in a trapped ion system.”

Art projects can fundamentally be anything you like, as long as you say they’re art at the end of it all. They don’t always work, or work well, but they often explore new ideas. Often, artists working on installations fall back on similar tools and techniques used by the maker community. [Julian] is no exception, and his Biotic Explorers work has many touchstones that will be familiar to the Hackaday set.

The Biotic Explorers Research Group is a broad art project, involving the creation of a fictitious scientific association. [Julian] created imaginary scientists, reports, and research to flesh out this world. The project culminates in the development of a prototype communications system, which uses pH sensors at either end of a fungal network in soil to send messages.

Liquids are applied to change the pH of the system, which can be picked up at the other end of the soil bed. The pH levels are read as digital signals, with pH levels either side of neutral reading as high and low bits. pH sensors can be expensive, so [Julian] chose the cheapest available, and tapped into their LCD display lines to read their output into an microcontroller. The system displays data using commonly available OLED displays, and hobby servo motors are used to control the dispensing of liquid.

Quantum mechanics had a disordered beginning in the 1920s, and is still developing today. Science is rarely a done deal, says Chanda Prescod-Weinstein

The ancient Celts were fierce warriors who lived in mainland Europe. But during the Renaissance, an idea took hold that they lived in the British Isles.

The relationship between the individual human subject and the world was once the central focus of Western philosophy. Modern neuroscience has instead tended to assume that the world is purely material and physical, and the problem of consciousness a question of how to generate thought from matter. Yet, we are no closer to solving the deep puzzle of consciousness and many argue that the American philosopher Thomas Nagel is right when he maintains that the question of consciousness ‘cannot be detached from subject and object’.

Is the notion that the world is purely material a fundamental mistake? Would we be more likely to unlock the mysteries of consciousness by once again adopting the framework of the subject and object? Or will slow, piecemeal advances in neuroscience and analytic philosophy eventually yield the answers that we have been searching for?

Revolutionary cognitive psychologist Donald Hoffman (joining us live from across the pond), neuroscientist Hannah Critchlow and philosopher Sam Coleman battle to unlock consciousness. Hosted by award-winning novelist Joanna Kavenna.

The living mycelium networks are capable of efficient sensorial fusion over very large areas and distributed decision making. The information processing in the mycelium networks is implemented via propagation of electrical and chemical signals en pair with morphological changes in the mycelium structure. These information processing mechanisms are manifested in experimental laboratory findings that show that the mycelium networks exhibit rich dynamics of neuron-like spiking behaviour and a wide range of non-linear electrical properties. On an example of a single real colony of Aspergillus niger, we demonstrate that the non-linear transformation of electrical signals and trains of extracellular voltage spikes can be used to implement logical gates and circuits.

“One of the greatest shifts that will occur in our lifetimes is going from driving to being driven.”

Kyle Vogt, CEO of GM’s driverless car maker Cruise (YC W14), aims to have a fleet of at least 1 million robo-taxis on U.S. roads by 2030 and in markets like Japan and Dubai. vehicles will overtake human-driven cars in ten years, the CEO of GM’s Cruise predicts.

It’s a very modern conjurer’s trick: Create a SXSW talk out of thin air, with the help of generative AI. That’s what whurley did this year in Austin. It took nine weeks for whurley — a staple of the Austin tech scene — to create and prepare for a keynote at SXSW 2018, where he would debut Strangeworks, a quantum computing startup he co-founded and runs. Five years later, generative AI would complete the task in just a few hours.

And it was actually pretty good. The 45-minute speech was comprehensive, interesting and struck a whurley-like tone. There was one swear word (fuck) and a few jokes (including two lawyer ones) that the audience laughed at.
