When two observers measure an entangled state, the frequencies of their observed results manifest the strength of quantum theory. Extreme values governing these statistics have now been successfully ...

Quantum statistics has long provided the theoretical framework for understanding the behaviour of particles at microscopic scales, traditionally delineated by Bose–Einstein and Fermi–Dirac ...

The study of quantum dots has advanced our understanding of electron transport at the nanoscale. These semiconductor nanostructures, which confine electrons in discrete energy levels, provide an ideal ...

A new study explores how EOS transmits ultrashort laser pulses through crystals that change in response to an applied electric field. This technique allows researchers to accurately capture the shape ...

Amplifier’s ability to operate at frequencies greater than 20 gigahertz provides path forward for more scalable quantum computing while controlling noise from thermal photons.

Researchers from the School of Physics at Wits University, working with collaborators from the Universitat Autònoma de Barcelona, have demonstrated how quantum light can be engineered in space and ...

Quantum computing promises a new generation of computers capable of solving problems hundreds of millions of times more quickly than today’s fastest supercomputers. This is done by harnessing spooky ...

For nearly a century, some of the strangest questions in physics have revolved around how quantum objects move, interact and share information in ways that defy everyday intuition. Now a cluster of ...

Quantum computing is generating a lot of excitement in the tech world right now. Following several recent breakthroughs, this once theoretical technology is increasingly accessible to researchers and ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...
