The errors that quantum computers make are holding the technology back. But recent progress in quantum error correction has ...

A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement.

To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional ...

Adiabatic quantum computing An example problem represented by an energy landscape. Each point on the landscape represents a candidate solution. The deepest valley represents the actual solution with ...

Saturday Night Fever: you may remember the dance performed by John Travolta and Karen-Lynn Gorney to the Bee Gees song (1) "More than a woman". The two dancers perform a perfectly prepared dance, ...

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a manuscript for publication. Its centerpiece was an innocuous-looking equation ...

Canadian quantum computing startup Photonic Inc. said today it has closed on CAD$180 million ($130 million) in funding as part of the first phase of its latest investment round. The company said it’s ...

What is it about quantum computers that makes them more powerful than conventional machines? A new experiment shows that the property of “quantum contextuality” may be a key ingredient. Quantum ...

Researchers have shown that quantum signals can be sent from Earth up to satellites, not just down from space as previously believed. This breakthrough could make global quantum networks far more ...
