Optical toric code platform sets new record

Anyons form the basis for topological quantum computation and error correction, where the topological aspect of anyonic braiding is one of the important features that gives rise to fault tolerance. More qubits to control ...

ATLAS experiment observes light scattering off light

Light-by-light scattering is a very rare phenomenon in which two photons interact, producing another pair of photons. This process was among the earliest predictions of quantum electrodynamics (QED), the quantum theory of ...

New quantum sensor could improve cancer treatment

A new quantum sensor developed by researchers at the University of Waterloo's Institute for Quantum Computing (IQC) has proven it can outperform existing technologies and promises significant advancements in long-range 3-D ...

Putting photons in jail

A miniature prison for photons—that is the nanocavity discovered by scientists of the University of Twente. It is an extremely small cavity surrounded by an optical crystal, a structure of pores etched in two perpendicular ...

Researchers move closer to practical photonic quantum computing

For the first time, researchers have demonstrated a way to map and measure large-scale photonic quantum correlation with single-photon sensitivity. The ability to measure thousands of instances of quantum correlation is critical ...
