Feature: A Quantum of Silence
Single photons have weird yet useful behaviours, with applications ranging from secure communications to quantum computing. While current silicon photon sources often produce additional “noise photons” that interfere with these emerging technologies, new research has discovered a method to quieten this quantum chaos.
Feature: How Certain Can You Be?
A team of physicists has challenged the limits of Heisenberg’s famous uncertainty principle by measuring quantum particles with unprecedented accuracy.

Quantum cryptography experiments onboard a new Chinese Earth satellite foreshadow secret communications on a global scale with security guaranteed by the laws of physics.
Feature: When Parallel Worlds Collide
Bizarre quantum phenomena, such as particles tunnelling through barriers and behaving like waves, can be explained by subtle interactions between our world and others.
