Ramped fields create more robust entanglement between trapped-ion qubits

August 26, 2026 While quantum computing could be the future, it is currently plagued by finicky hardware. To make the technology practical, researchers must demonstrate that it consistently and continuously works and performs at scale. In a new study, published in Physical Review Letters, researchers at Lawrence Livermore National Laboratory (LLNL) and the Ion Storage

Scientists observe Einstein’s gravity in the quantum world

September 2, 2026 An international team including Nobel Prize-winning physicist Professor Sir Roger Penrose has observed a long-predicted effect of gravity on a falling quantum object for the first time. The result shows that a fundamental principle at the heart of Einstein’s theory of gravity remains consistent with the behavior of matter in the quantum

Unconventional quantum materials could dramatically boost the search for dark matter

September 9, 2026 For decades, physicists have searched for dark matter, the invisible substance thought to make up roughly 85% of all matter in the universe. Although its gravitational influence shapes galaxies and the large-scale structure of the cosmos, dark matter has never been directly detected. Now, an international team has identified a new class

Layer-based design offers new route to topological magnets

September 9, 2026 Topological quantum materials combine unusual electronic states with properties such as magnetism or superconductivity, offering possibilities for future electronics and quantum technologies. Researchers at Tohoku University have now shown that changing the number of layers in a crystal can provide a systematic way to design topological magnets. The work is published in

Could quantum protocols make electronic voting more secure?

September 9, 2026 Electronic voting, the use of electronic systems to cast, record or count votes, could potentially simplify the process of electing new political leaders or other representatives. While some countries have already started using internet-connected devices or electronic voting machines at polling stations, the trustworthiness, security and anonymity of electronic voting systems are

Making superconductors thinner can change how they accommodate magnetic fields

September 2, 2026 What happens when a superconductor becomes so thin that electrons can no longer behave as if they were moving through an ordinary three-dimensional piece of metal? This question has been at the center of my recent work on quantum confinement in metallic films. Over the past few years, I have been developing

A new game demonstrates quantum advantage with provable classical limits

September 8, 2026 For decades, physicists have worked to prove the strange predictions of quantum mechanics with real experiments. As quantum computers have grown more powerful, researchers have devised increasingly sophisticated ways to test whether these machines are truly harnessing quantum effects—but every method so far has run into limits.

Superfluid qubit could help scale up quantum computers

September 8, 2026 Superfluid helium could offer a new way to tackle one of the biggest challenges in scaling up quantum computers, say researchers from the University of Surrey. The research team has introduced a conceptual design for a new type of qubit that could be much less vulnerable to errors. Read the full article

A photon that challenges Einstein: According to current physics, it should never have reached Earth

September 8, 2026 How did a photon survive a journey of more than 2 billion light-years when, according to known physics, it should have been absorbed long before reaching Earth? This is the question at the heart of a new study by Giorgio Galanti (INAF) and Marco Roncadelli (INFN), accepted for publication in Physical Review

Physicists take Hall effect in a new direction

August 31, 2026 Carnegie Mellon University scientists have uncovered a new phenomenon that challenges a longstanding assumption about how electronic materials respond to magnetic fields. The discovery broadens the fundamental understanding of the Hall effect, a principle widely used to measure the magnetic and electronic properties of materials. Read the full article →
