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 new room-temperature quantum device developed at Stanford uses twisted light and advanced materials to link photons and ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...

For many of us, advanced physics can be tough to understand to begin with, which makes it all the more impressive whenever someone earns a Nobel Prize for advancing the field even further. The latest ...

One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

So, quantum computing teleportation. It sounds like something out of science fiction, right? But it’s actually a ...

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 ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...

Technological devices are getting ever smaller, but as they approach the scale at which quantum physics matters, our understanding of how they interact with their environment evaporates. James Millen ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...
