Slight temperature changes, imperceptible manufacturing imperfections, and heat generated by their own components can completely ruin an entire quantum quantum system-on-chip. Silicon photonics could ...

A breakthrough experiment led by a team from the University of Stuttgart in Germany brings a quantum internet a step closer, with physicists teleporting a quantum state between photons produced by ...

Light is usually treated as something simple, a clean beam that either shines or does not. At the quantum level, however, ...

Highly anticipated: Scientists at the University of Arizona have demonstrated a method to capture and manipulate quantum uncertainty in real time using rapid pulses of light, marking what they ...

In the classical world, a beam of light is a smooth, continuous wave. In the quantum realm, however, photons manifest as the discrete constituents (quanta) of light. These photons can be carefully ...

Researchers from Wits University and Universitat Autònoma de Barcelona show how controlling the structure of photons in space and time enables tailored quantum states for next-generation communication ...

Two-photon absorption and quantum light spectroscopy have emerged as transformative tools in modern optical research. At the heart of these techniques is the simultaneous absorption of two photons to ...

Quantum light sources often produce inconsistent or contaminated single photons, limiting the reliability of quantum technologies. Researchers coated atomically thin tungsten diselenide with a uniform ...

A programmable photonic circuit has been developed that can execute various quantum algorithms and is potentially highly scalable. This device could pave the way for large-scale quantum computers ...
