In a white paper written on the same day as the Caltech paper, Gidney and his colleagues announced that they had developed a new method for breaking ECC that was at least 10 times more efficient than previous methods. They estimate that most cryptocurrencies would provide seconds to a machine with less than 500,000 qubits. … Read more
A century later, the quantum the land is still incredibly productive and stubborn a miracle. Its equations are parallel laser devices and LEDsguide the MRI scanner, and underwrite the transistors that heat up our phones, yet leave us confused as to what numbers it really tells us about the truth. The theory predicts about amazing … Read more
By mid-2025, the group of physicists to Massachusetts Institute of Technology achieved something that had eluded researchers for nearly a century: the direct visualization of an obscure “second sound.” This is a rare regime there temperature it is no longer different but moves like the wavehumming like sound in a quantum liquid. The findings, published … Read more
As digital communication accelerates and cyber threats increase, researchers are working to develop more secure ways to transmit information. One of the most promising methods is quantum cryptography, which uses individual photons to generate encryption keys. A team of researchers from the Department of Physics at the University of Warsaw has developed and tested a … Read more
A Theory of Gravity That Could Rewrite the Universe’s First Minutes The first fraction of a second after the Big Bang has always posed a problem. Physics can explain a lot about the universe once it’s stable and expanding, but in the beginning, when heat and energy were extremes, it was still hard to pin … Read more
Modern cosmology is built on three theoretical pillars: special relativity, Newtonian gravity, and quantum mechanics. Each is supported by considerable experimental evidence, but each describes the physical world in a way that contradicts the other two. Quantum theory describes a small. Objects that are driven by electromagnetic forces, both strong and weak. The dim world … Read more
Inside Short New research from Caltech and Oratomic suggests that fault-tolerant quantum computers may only need 10,000-20,000 qubits—much fewer than previously thought—which could speed up times up to this decade. The team has developed highly efficient quantum error correction systems using systems of neutral atoms, reducing the number of physical qubits from 1,000 to five. … Read more
From scaling to error correction, many problems still need to be solved before a working quantum computer can be built, but researchers continue to find the necessary solutions. Quantum computers can be used to solve complex problems that are impossible for the most conventional computer. But building a working quantum computer is, of course, not … Read more
Isosurface of the Dyson orbital, taken from Piccinelli, Samuele, et al., “Exploring paths towards quantum chemistry: the case of a molecule with a half-Möbius topology,” arXiv, 9 March 2026. arXiv:2603.08696 A recent paper in the journal Science announced the discovery of a truly new and surprising substance that could have a major impact on our … Read more
Light usually travels in straight paths, but what if it was twisted, spun, and behaved like a mini-tornado? Scientists have now made this possible by creating optical vortices—small swirling particles of light in a microscopic system. Until now, generating such complex light systems required multiple setups or complex nanostructures, making it difficult to scale. A … Read more
