Amid high expectations for quantum technology, a new paper in Science reports a proven quantum advantage. In an experiment, ...

A paradox at the heart of quantum physics has been tested in an extraordinary fashion, pushing the boundaries of human intuition beyond breaking point by measuring a pulse of light in 37 dimensions.

The Irish mathematician and physicist William Rowan Hamilton, who was born 220 years ago last month, is famous for carving some mathematical graffiti into Dublin's Broome Bridge in 1843.

In a Caltech lab, a computer screen showed thousands of tiny points of light—each one a single atom, held in place by laser ...

A survey of Scientific American’s century of quantum coverage helps explain the enduring popularity of strange physics ...

Photosynthesis and other natural processes depend on energy moving quickly and efficiently across molecules. When sunlight strikes a leaf, energy races across protein structures before it can be ...

Caltech physicists report they have created the largest qubit array assembled to-date: 6,100 neutral-atom qubits trapped in a ...

While many plans for quantum computers transmit data using the particles of light known as photons, researchers from the ...

The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

Fluorescent proteins can be turned into qubits within cells and could give us a deeper understanding of biology at the ...

Made out of a fluorescent protein, the qubit is just 3 nanometers in diameter, scientists report August 20 in Nature. By hitting the protein with laser light, tweaking it with microwaves and observing ...

Scientists created the first working quantum money system that cannot be counterfeited using light particles and quantum ...
