This idea puts a morbid twist on quantum theory, suggesting that a copy of you may remain alive, no matter what.

Negative time is a peculiar quirk of quantum mechanics, like the possibility of an object being in two places at one time (think: Schrodinger’s cat ... Einstein’s theory of special relativity ...

The weird paradox of Schrödinger’s cat has found a lasting popularity. What does it mean for the future of quantum physics?

In 1935, the Austrian physicist Erwin Schrödinger published a rather critical three-part review of what he called the ‘present situation’ in the relatively new theory of quantum mechanics. For the ...

Explore the key moments in the history of quantum theory, from the early ideas of Albert Einstein and Werner Heisenberg to ...

Physicists have created a Schrödinger's cat state at unusually hot temperatures, and it could be a major step toward the development of practical quantum computers. Schrödinger's cat states ...

In 1935, Erwin Schrödinger used a thought experiment now known as “Schrödinger’s cat” to emphasize what he saw as a problem with some interpretations of quantum theory. His gedankenexperiment involved ...

The energy required can be calculated using quantum electrodynamics (QED)—the quantum theory of electromagnetism. However, insufficient knowledge of the structure of such heavy atomic nuclei ...
