Two stopped light pulses interact with each other

(Phys.org) -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the efficiency with ...

First-ever calculation performed on optical quantum computer chip

(PhysOrg.com) -- A primitive quantum computer that uses single particles of light (photons) whizzing through a silicon chip has performed its first mathematical calculation. This is the first time a calculation has been performed ...

Bringing a power tool from math into quantum computing

The Fourier transform is an important mathematical tool that decomposes a function or dataset into a its constituent frequencies, much like one could decompose a musical chord into a combination of its notes. It is used across ...

Quantum sound waves to open doors for more powerful sensors

For the last decade, scientists have been making giant leaps in their ability to build and control systems based on the bizarre rules of quantum mechanics, which describe the behavior of particles at the subatomic scale.

Scaling silicon quantum photonic technology

An international team of quantum scientists and engineers led by the University of Bristol and involving groups from China, Denmark, Spain, Germany and Poland, have realised an advanced large-scale silicon quantum photonic ...
