How to overcome noise in quantum computations

Researchers Ludovico Lami (QuSoft, University of Amsterdam) and Mark M. Wilde (Cornell) have made significant progress in quantum computing by deriving a formula that predicts the effects of environmental noise. This is crucial ...

Scientists boost quantum signals while reducing noise

A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer, which harnesses quantum mechanical phenomena to solve certain problems too complex ...

A diamond-based quantum amplifier

In physics, weak microwave signals can be amplified with minimal added noise. For instance, artificial quantum systems based on superconducting circuits can amplify and detect single microwave patterns, although at millikelvin ...

Quantum leap for research into unhackable communications networks

Scientists at Heriot-Watt University in Edinburgh, Scotland, have published new research into the phenomenon known as quantum entanglement. This is when two particles—such as photons of light—remain connected even when ...

Nanoengineers boost signals from fluorescent sensors

Fluorescent sensors, which can be used to label and image a wide variety of molecules, offer a unique glimpse inside living cells. However, they typically can only be used in cells grown in a lab dish or in tissues close ...
