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 ...

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 ...

Physicists prove a long-suspected quantum speed limit for thermalization
Whether we are waiting for a car windshield to defrost in winter or a warm drink to cool down, how long it takes for an object to settle into a stable, even temperature within its environment (thermal equilibrium) depends ...
Hybrid diamond chip strengthens interactions between light and quantum bits
Researchers have developed and demonstrated a new hybrid photonic platform that integrates quantum emitters with photonic devices, providing a way to reliably control the interaction between photons and quantum information ...

Quantum magic state cleanup cuts errors 40-fold in first successful hardware test
Qubits, the quantum equivalent of digital bits, are fragile and prone to errors. That makes building reliable quantum computers extremely difficult. One fix has been to use traditional magic state distillation, which filters ...
New high-frequency method boosts 2D material readout for next-gen quantum computers
Quantum computers represent a next step in the fast-paced evolution of technology. Using quantum bits (qubits), they have the potential to run certain calculations exponentially faster than conventional computers. However, ...
