Free-space quantum secure direct communication (QSDC) does not require the laying of optical fibers, which can effectively prolong the transmission distance and break the limitation of terrain. It is ...

How much does a quantum measurement disturb what comes next? A team at TU Wien has discovered a surprisingly simple formula that sets a fundamental limit on the trade-off between measurement ...

During the 2024-25 school year, students in Southern Adventist University’s physics club taught lessons about the basics of Quantum Information Science and Technology (QUIST) at three local schools.

“Einstein and Bohr would have never thought that this is possible, to perform such an experiment with single atoms and single photons,” said Wolfgang Ketterle, head of the MIT group whose new ...
