It has taken 20 years of development, but researchers now have a device that can scale to millions of qubits without errors ...

One of the tiniest building blocks of the universe has a weigh-in problem, and Ashutosh Kotwal is determined to get to the ...

What makes something quantum? This question has kept a small but dedicated fraction of the world's population—most of them ...

Physicists have developed a novel approach to maintain special quantum characteristics, even in 3D materials, with potential applications in optical systems and advanced computing.

Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to ...

Density describes how closely packed the particles are in a solid, liquid or gas. There is little difference between the density of a liquid and its corresponding solid (eg water and ice).

Matter is made up of small particles called atoms. Atoms can exist on their own or together as molecules. Atoms are very small and around 100,000,000 of them end to end would measure 1 centimetre.
