A new type of chemistry performed at very cold temperatures on very small particles enables quick, precise reactions.
Quantum computing could give us machines massively more powerful than today’s, but we still have a long way to go, say leaders in the field.
The tech story of the century so far has been the mainstream arrival of generative artificial intelligence, which drives the uncanny capabilities of systems such as ChatGPT, and is fast being absorbed into our everyday lives.
Whether to mimic human creativity, double as empathetic counsellor or eliminate clerical drudgery, generative AI has delivered an unprecedented surge in excitement for its potential benefits.

Sandia’s 20 year experience in building and testing ion traps has culminated in its latest offering: the Enchilada Trap.
Sandia National Laboratories revealed the Enchilada Trap, a groundbreaking ion trap central to some quantum computers, in a press release.
This innovative device promises to reshape the landscape of quantum computing, providing researchers with a potent tool to explore the experimental and transformative field of quantum computation.
The central problem quantum state engineering is trying to solve, says Ryan Glasser is “what do I need to do to get my quantum system to be in the state I desire?” Researchers hope ManQala, a version of the ancient game mancala, has answers. (Credit: Tobias Tullius/Unsplash)
The game mancala may have originated as far back as 6,000 BCE in Jordan and is played around the world to this day. It consists of stones that players move between a series of small pits on a wooden game board. The point of the game is to get all the stones into the last pit at the end of the board.
The crisis of understanding, according to Popper, arose in physics along with the Copenhagen interpretation, or, more precisely, from the point of view of Bohr and Heisenberg on the status of quantum mechanics.
In his opinion, quantum mechanics should be interpreted as the last revolution in physics, since the inherent boundaries of knowledge were reached in it.
Quantum computing, just like traditional computing, requires a method to store the information it uses and processes. In the computer you’re using right now, information—whether it be photos of your dog, a reminder about a friend’s birthday, or the words you’re typing into your browser’s address bar—must be stored somewhere. Quantum computing, a relatively new field, is still exploring where and how to store quantum information.

As the name implies, Nature Physics is a peer-reviewed, scientific journal covering physics and is published by Nature Research. It was first published in October 2005 and its monthly coverage includes articles, letters, reviews, research highlights, news and views, commentaries, book reviews, and correspondence.
The Defense Advanced Research Projects Agency (DARPA) has announced a new program it says will develop synthetic metamaterials that could lead to breakthroughs in quantum computing and information science.
Called the Synthetic Quantum Nanostructures program, or SynQuaNon, the new DARPA initiative “aims to address this challenge with a fundamental science effort that seeks to develop synthetic metamaterials to enable enhanced functionalities and novel capabilities,” read a statement issued by the agency this week.
The program aims to produce a range of new quantum materials that will have a variety of uses in quantum computing and other information science applications.
They use a process called DNA origami.
This is according to a press release by the institution published on Friday.
TV screens equipped with quantum rods have the ability to generate 3D images for virtual reality devices. Now, MIT engineers have conceived of a way to precisely assemble arrays of quantum rods in the devices using scaffolds made of folded DNA that allow depth and dimensionality to be added to virtual scenes.

Irradiating a uniaxial magnetic system with a specific sequence of microwave pulses can induce in the system quantum oscillations that cause the material’s spins to flip back and forth.
To make higher-density magnetic data systems, researchers are looking to crystalline materials that have switchable magnetic orientations. But for some of these materials, switching the magnetization direction—for example from spin-up to spin-down—requires overcoming a large energy barrier. Now Seiji Miyashita at the University of Tokyo and Bernard Barbara of the Institut Néel, CNRS Grenoble, France, predict that experimentalists could reverse a material’s magnetization by applying to it a specific sequence of microwave or optical-frequency pulses [1]. The approach could find applications in quantum information storage.
To reverse the spin of a magnetic material, researchers can apply high temperatures or high magnetic fields to push the system over the potential energy barrier that separates its spin states. Another option is to induce resonant quantum tunneling to move electrons through the barrier. Miyashita and Barbara propose a further method that bypasses the constraints associated with the application of intense magnetic fields in these previous methods.
Practical applications for quantum entanglement have already been proposed, as entangled particles have been suggest for use in powerful quantum computers and “impossible” to crack networks. Now, it seems quantum entanglement may be linked to wormholes.
