Researchers have developed a special type of amplifier that uses a technique known as squeezing to amplify quantum signals by a factor of 100 while reducing the noise that is inherent in quantum ...

The ability to achieve quantum-limited amplification of optical signals contained in optical fibers is arguably among the most important technological advances that are underlying our modern ...

Quantum computing, an approach to deriving information that leverages quantum mechanical effects, relies on qubits, quantum units of information that can exist in superpositions of states. To ...

Modern communication networks rely on optical signals to transfer vast amounts of data. But just like a weak radio signal, these optical signals need to be amplified to travel long distances without ...

A focus-stacked macro photograph of a fabricated gallium phosphide photonic chip featuring multiple spiral waveguides and other test structures. The chip width is just 0.55 cm across. Due to the high ...

Scientists at EPFL, Lausanne, Switzerland, have developed photonic integrated circuits that demonstrated a new principle of light amplification on a silicon chip. They say can be employed for optical ...
