'One-positron cyclotron' could test a key prediction of the Standard Model
The positron is the antimatter counterpart of the electron, identical in mass but carrying an equal and opposite electric charge. Like the electron, it also behaves like a tiny bar magnet, and according to a key prediction ...
Counting magnetic flux quanta offers new way to measure photon numbers
Researchers at AIST have directly observed magnetic flux quanta generated in a superconductor by photon absorption and demonstrated a new principle of photon detection that identifies the number of photons based on the number ...

Experiment shows when quantum 'cat' states stop bouncing back
Quantum systems can occupy superpositions, quantum states that combine different possibilities. For instance, a microwave field can be prepared in a superposition of an empty state and a state that contains microwave light.
Light-based method enables precise control of ultrafast electron flow in a scanning tunneling microscope
What would it take to watch an electron move through a material? Researchers would need to see individual atoms and capture an electron's motion at incredibly short timescales. A Technion-led team has brought those two capabilities ...

Quantum interference traps electron waves in metal for first time
Ever since quantum mechanics first described particles, like electrons, as rippling waves, researchers have wondered if those waves could be trapped in place. Writing today in Science a century later, a team of Columbia University ...

Lost Schrödinger manuscript reveals his true view of quantum randomness
Unlike classical physics, quantum mechanics generally cannot tell us exactly what will happen in an individual event. Instead, it predicts the probabilities of different outcomes. As one of the theory's early pioneers, Erwin ...
Laser-made lattice reveals discrete light solitons in tunable atomic vapor
Scientists from the Quantum Technologies Group at the Institute of Physics Zagreb, in collaboration with a colleague from the Physics Department at the Faculty of Science (PMF), have experimentally demonstrated for the first ...

Atomic memory keeps distant ions entangled for about 10 seconds
Quantum networks, systems that connect devices and allow them to exchange information encoded in the quantum states of particles, could enable more secure communications. To build these networks, physicists need to devise ...
A hidden rivalry between two quantum states at the heart of superconductors
Transmitting electricity without losing any energy may sound impossible, yet this is precisely the promise of superconductivity. For nearly 40 years, scientists have been working to understand materials that exhibit this ...

Steering electrons with extreme ultraviolet light—team achieves quantum coherent control
Light is one of the most powerful tools scientists have for probing matter. By interacting with electrons, light reveals how atoms, molecules and materials are structured and how they evolve in time. Highly energetic ultraviolet ...

Individual atomic collisions can now be detected in the lab, potentially opening up pathways to new physics
Tiny atoms and molecules are constantly bombarding each other all around us. While we regularly measure the large-scale effects of these interactions, measuring the effect of each individual collision is far more difficult. ...
Quantum probability can't be derived without assuming it first
For nearly a century, physicists have relied on the Born rule to calculate the chances of different outcomes when they measure a quantum system. Yet despite decades of effort, nobody has managed to derive the rule from more ...
A quantum pathway to entropy-free energy transfer
For scientists, breakthroughs often stem from unexpected turns. A research team led by Oscar Dahlsten, an associate professor in the Department of Physics at City University of Hong Kong (CityUHK), set out to prove a theoretical ...
