In a laboratory at Oxford University, scientists have achieved something that once seemed science fiction: they made two separate quantum computers work together as one. Instead of being connected by wires, these machines shared information through light, effectively forming a single, unified quantum computer. The experiment marks the first time researchers have run a full quantum algorithm across two distant …

Using ultra-fast laser pulses and special cameras, scientists have simulated an optical illusion that appears to defy Einstein’s theory of special relativity. One consequence of special relativity is that fast-moving objects should appear shortened in the direction of motion — a phenomenon known as Lorentz contraction. This effect has been confirmed indirectly in particle accelerator experiments. But in 1959, mathematician …

IN A NUTSHELL 🌌 Physicists propose the universe may eventually collapse under its own gravity due to evolving dark energy. 🔍 A new model suggests a finite lifespan of 33.3 billion years, with less than 20 billion years remaining. 🪐 The study highlights a negative cosmological constant (λ) that could reverse the universe’s expansion. 🔬 The role of axions is …

If recent discoveries that dark energy is evolving hold any water, our Universe will collapse under its own gravity on a finite timeline, new calculations suggest. Based on several recent dark energy results, a new model finds that the Universe has a lifespan of just 33.3 billion years. Since we are now 13.8 billion years after the Big Bang, this …

Can you prove whether a large quantum system truly behaves according to the weird and wonderful rules of quantum mechanics — or if it just looks like it does? In a groundbreaking study, physicists from Leiden, Beijing en Hangzhou found the answer to this question. You could call it a ‘quantum lie detector’: Bell’s test designed by famous physicist John …

A black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing. Using a chain of atoms in single file to simulate the event horizon of a black hole, a team of physicists in 2022 observed the equivalent of what we call Hawking radiation – particles born from disturbances in the …

Under the right conditions, superconducting magnets allow electricity to flow essentially undisturbed, producing intense magnetic fields for a variety of uses, including nuclear fusion experiments. Naturally, a larger magnetic field gives scientists more room to explore—something that may soon be available to physicists in China, thanks to the creation of a record-setting superconducting magnet. In a September 28 statement, the …

Stellar black holes form from the collapse of massive stars at the end of their lives, typically weighing 3 to 50 times the mass of the sun. When a star runs out of fuel, it explodes in a supernova, leaving behind a region so dense that nothing can escape, not even light. Primordial black holes, by contrast, are theoretical objects …
