Searching for errors in the quantum world

The theory of quantum mechanics is well supported by experiments. Now, however, a thought experiment by ETH physicists yields unexpected contradictions. These findings raise some fundamental questions—and they're polarising ...

Should your driverless car kill you to save a child's life?

Robots have already taken over the world. It may not seem so because it hasn't happened in the way science fiction author Isaac Asmiov imagined it in his book I, Robot. City streets are not crowded by humanoid robots walking ...

Authors' 'invisible' words reveal blueprint for storytelling

The "invisible" words that shaped Dickens classics also lead audiences through Spielberg dramas. And according to new research, these small words can be found in a similar pattern across most storylines, no matter the length ...

Schrödinger's cat with 20 qubits

Dead or alive, left-spinning or right-spinning—in the quantum world particles such as the famous analogy of Schrödinger's cat can be all these things at the same time. An international team, including researchers from ...

The 'great smoky dragon' of quantum physics

University of Vienna physicists have, for the first time, evaluated the almost 100-year long history of quantum delayed-choice experiments—from the theoretical beginnings with Albert Einstein to the latest research works ...

Four common misconceptions about quantum physics

Quantum mechanics, the theory which rules the microworld of atoms and particles, certainly has the X factor. Unlike many other areas of physics, it is bizarre and counter-intuitive, which makes it dazzling and intriguing. ...
