Quantum entanglement, a bewildering phenomenon where particles become interconnected regardless of the distance separating them, challenges our fundamental understanding of reality. It has puzzled ...

Here’s what you’ll learn when you read this story: Creating quantum entanglement from scratch can be tricky business, so researchers are exploring ways that entangled pairs can “share” these states ...

In their experiments, the team observed that the entanglement within the dark state could last up to 36 nanoseconds—a lifetime approximately 600 times longer than the 62 picoseconds typical of bright ...
