Medicine & TechnologyResearchers have successfully demonstrated a secure transmission using measurement-device-independent quantum key distribution (MDI-QKD) protocol, sending information over 170 kilometers.
Technological advancements have allowed physicists to manipulate and study quantum particles, their states, and their interactions. However, they still need to figure out how to keep quantum systems from decaying long enough to practically run computations and transfer information—and a simple solution might just solve the problem
Physicists from Yale University have developed an "error-correcting cat". This device combines the concept of superposition from the famous Schrödinger's cat experiment, and the ability to fix some of the persisting problems with quantum computation.
Every science fiction fan is familiar with the notion of parallel universes with the Star Trek series being one of the first to popularize the notion. However, thanks to the Large Hadron Collider, we may soon have proof that a parallel universe does, in fact, exist.
