Quantum optics investigates the quantum properties of light and its interaction with matter at the level of individual photons. It encompasses the generation, control and detection of non-classical ...

The 5.4 km free-space quantum communication link between the University of Ottawa and the National Research Council Canada, where real-time atmospheric turbulence measurements were conducted to train ...

A new study explores the behavior of photons, the elementary particles of light, as they encounter boundaries where material properties change rapidly over time. This research uncovers remarkable ...

Researchers have found a clever way to make quantum dots, tiny light-emitting crystals, produce streams of perfectly controlled photons without relying on expensive, complex electronics. By using a ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

For the first time, our team at the Insti­tute for Exper­i­men­tal­physik at Inns­bruck Univer­sity in collab­o­ra­tion with ...

In context: Quantum computers are all about qubits, the basic units that operate according to the principles of quantum mechanics instead of the zeros and ones of today's computers. They promise ...

But after reading Decoherence and Quantum Darwinism, a book published in March 2025 by the physicist Wojciech Zurek, I’m excited by the possibility of an answer that does away with all those fanciful ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
