An international research team involving Paderborn University has achieved a crucial breakthrough on the road to a quantum internet. For the first time ever, the polarization state of a single photon ...

The proposed method uses a single rare-earth ion, trapped inside a tapered optical fiber, to directly generate and guide single photons within the fiber, representing a key low-cost component for ...

QuiX Quantum, a Dutch photonic quantum computing pioneer, has secured more than $17 million in Series A funding to deliver the world’s first single-photon-based universal quantum computer in 2026. The ...

Controlling light at the level of individual photons could one day do for quantum networks what switching and routing have done for classical internet infrastructure. To help realize that vision, ...

Researchers at RIKEN have demonstrated experimentally that a microwave photonic circuit device known as a Josephson traveling-wave parametric amplifier (JTWPA) can achieve the low-noise, high-gain ...

Sparrow Quantum, a Copenhagen-based startup specializing in single-photon emitters suitable for a range of quantum technology applications, has raised €21.5 million in a series A funding round. Led by ...

An experiment measuring a single atom's recoil confirmed that observing a particle destroys interference, settling the ...

Physicists have now teleported the quantum state of a single photon between distant quantum dots, turning a long theorized building block of the quantum internet into a working device. By reliably ...
