No 'second law of entanglement' after all, claims study

The second law of thermodynamics is often considered to be one of only a few physical laws that is absolutely and unquestionably true. The law states that the amount of 'entropy'—a physical property—of any closed system ...

New type of entanglement lets scientists 'see' inside nuclei

Nuclear physicists have found a new way to use the Relativistic Heavy Ion Collider (RHIC)—a particle collider at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory—to see the shape and details inside ...

Researchers develop a light source that produces two entangled light beams

Scientists are increasingly studying quantum entanglement, which occurs when two or more systems are created or interact in such a manner that the quantum states of some cannot be described independently of the quantum states ...

High-visibility quantum interference between two independent semiconductor quantum dots achieved

This year's Nobel Prize in Âé¶¹ÒùÔºics celebrated the fundamental interest of quantum entanglement, and also envisioned the potential applications in "the second quantum revolution"—a new age when we are able to manipulate ...

Did physicists make a wormhole in the lab? Not quite, but a new experiment hints at the future of quantum simulations

Scientists made headlines last week for supposedly generating a wormhole. The research, reported in Nature, involves the use of a quantum computer to simulate a wormhole in a simplified model of physics.

Using 'cat states' to realize fault-tolerant quantum computers

Error correction in quantum computers could be simplified by a new protocol proposed by an all-RIKEN team based on "cat states." It could cut the computing resources needed to fix errors to the same level as conventional ...
