Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

(via PBS Space Time) Does quantum mechanics allow the future to retroactively influence the past, as in the infamous delayed choice quantum eraser experiment? How about we get an actual quantum ...

Researchers have demonstrated a type of quantum eraser. The physicists show that they can pinpoint and correct for mistakes in quantum computing systems known as 'erasure' errors. Quantum computers of ...

In 2023, researchers revisited the Quantum Eraser experiment with updated technology and disturbing results. Evidence suggests that observation and measurement might alter the past. Such findings have ...

Quantum entanglement is a fundamental phenomenon in nature and one of the most intriguing aspects of quantum mechanics. It ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

While errors are normally hard to spot in quantum devices, researchers have shown that, with careful control, some errors can cause atoms to glow. Researchers used this capability to execute a quantum ...
