First formulated in 1935, the famous thought experiment attempts to explain the weirdness of quantum superposition, but a new ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

A research team has, for the first time in the world, elucidated the microscopic mechanism by which quantum order is lost and collapses in "open quantum environments" existing in nature. Since ...

Researchers have shown that ultracold atoms can be driven into a strange new quantum state called a fractional Fermi sea, where particles organize themselves in unexpected ways. The discovery points ...

The approach is known for high accuracy, but scaling it up while preserving that accuracy is technically difficult. Helios ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction. Yet daily life ...

NASA's upgraded Cold Atom Lab came back online aboard the International Space Station this week — the fourth and final hardware overhaul of a facility that has spent eight years turning the ISS into ...

Quantum mechanics, the theory governing the microscopic world, is famously counterintuitive. A particle can exist in a superposition of multiple states, such as different positions, until a ...

Physicists at UC Santa Barbara have uncovered a new way to manipulate unusual magnetic states by exploiting “frustration” inside a crystal’s atomic structure. The team discovered a rare system where ...

Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their ...

Quantum measurement dynamics explores how the act of observation influences the state of a quantum system, with particular emphasis on spin degrees of freedom under both continuous and projective ...
