Theoretical physicists routinely introduce fictitious particles and fields in their calculations, in view of completing a theory or simply to make it more elegant. A striking example concerns the magnetic monopole imagined by Dirac in 1931: a […]

Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There […]
Quantum computing continues to advance at a rapid pace, but one challenge that holds the field back is mitigating the noise that plagues quantum machines. This leads to much higher error rates compared to classical […]
Whether it’s photovoltaics or fusion, sooner or later, human civilization must turn to renewable energies. This is deemed inevitable, considering the ever-growing energy demands of humanity and the finite nature of fossil fuels. Much research […]

A study led by Dr. Guancong Ma (Department of Physics, Hong Kong Baptist University, Kowloon Tong, Hong Kong, China) and Dr. Kun Ding (Department of Physics, Fudan University, Shanghai 200438, China) provides a new perspective […]
In recent years, physicists have discovered materials that are able to switch their electrical character from a metal to an insulator, and even to a superconductor, which is a material in a friction-free state that […]
Fragments of the interior of a proton have been shown by scientists from Mexico and Poland to exhibit maximum quantum entanglement. The discovery, already confronted with experimental data, allows us to suppose that in some […]
Contextuality is essential to explain the power of quantum computers and the security of quantum communications. The study has been published in the journal Science Advances. Click to rate this post! [Total: 0 Average: 0]You […]
Quantum computers are getting bigger, but there are still few practical ways to take advantage of their extra computing power. To get over this hurdle, researchers are designing algorithms to ease the transition from classical […]
