Quantum dots, semiconductor nanostructures exhibiting discrete energy levels, have emerged as quintessential quantum emitters for on‐demand single-photon generation. Their unique confinement ...

Leveraging the principles of quantum mechanics, quantum computers can perform calculations at lightning-fast speeds, enabling them to solve complex problems faster than conventional computers. In ...

Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative ...

The consortium of the BMBF project SPINNING coordinated by Fraunhofer IAF has succeeded in decisively advancing the development of spin-photon-based quantum computers. On October 22 and 23, 2024, the ...

Data security on the internet is under threat: in the future, quantum computers could decode even encrypted files sent over the internet in no time. Researchers worldwide are, therefore, experimenting ...

For quantum communication to work, light sources must emit photons one at a time, not in random bunches. Several materials ...

Quantum entanglement has shifted from a philosophical puzzle to a design brief for engineers working at the scale of atoms, ...

The BMFTR-funded SPINNING project has successfully demonstrated that hybrid-integrable, scalable, and near-room-temperature solid-state quantum components represent a robust and energy-efficient ...

A new chip-based quantum memory uses 3D-printed “light cages” to store light in atomic vapor with high precision. Quantum ...

A group of South Korean researchers has successfully developed an integrated quantum circuit chip using photons (light particles). This achievement is expected to enhance the global competitiveness of ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...
