An international research team has controlled hybrid electron-photon quantum states in helium atoms. Control of these special quantum states was enabled by the pulse formation of very intense ...

In the world of quantum physics, the rules that govern reality behave in ways that challenge what we think we know. Particles ...

Quantum sensing has transformational potential across many areas of technology and science, most prominently biomedical ...

Through carrier multiplication, in which a single absorbed photon generates two electron-hole pairs, called excitons, quantum dots have the unique ability to convert photons more efficiently to ...

Quantum properties of each photon emitted -- such as the photon's polarization, wavelength and/or emission timing -- can function as a quantum bit of information, or "qubit," for quantum computing ...

As we celebrate the International Year of Quantum 2025, the frontier of light-matter interaction is undergoing a revolution. These advances are poised to transform technology, from medical imaging to ...

Because they are strongly bound, the electron quickly returns to the atom. When it does this, it releases a single photon encoded with very specific quantum information.

Swiss research center EPFL has used an integrated photonics approach to efficiently modulate an electron beam, potentially offering a new platform for investigations into free-electron quantum optics.

Such experimental verification of the quantum nature of energy emitted from a single quantum dot was done for a single atom in 1977 and for a single molecule in 1992.

Light excites the quantum dot core, transferring energy to a magnetic manganese ion through ultrafast sub-picosecond spin exchange. The manganese ion then undergoes spin-flip relaxation, resulting ...
