Quantum theory and general relativity have long described the universe with incompatible languages, one speaking in probabilities and the other in smooth curves of spacetime. A new line of work argues ...
The collaboration of TU Wien with research groups in China has resulted in a crucial building block for a new kind of quantum computer: The realization of a novel type of quantum logic gate makes it ...
A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending ...
Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...

The quantum physics behind why we forget
Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...
For bringing quantum effects to a scale once thought impossible, three physicists have won the 2025 Nobel Prize in physics. In the 1980s, John Clarke, Michel Devoret and John Martinis demonstrated the ...
