When a molecule of tryptophan absorbs ultraviolet light, it glows faintly as it lets off lower-frequency energy. This soft glow, known as fluorescence, is a familiar effect. But when many tryptophan ...

Some researchers believe consciousness is a byproduct of the constantly firing web of neurons in our heads. However, others believe something more theoretical must be involved to explain our complex ...

Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the diameter of a human hair. Subscribe to our newsletter for the latest sci-tech ...

Quantum Art's new QPU could be both significantly smaller and also faster than competing quantum architectures. How can we reinvent quantum computing? Perhaps by shrinking it down and making it small: ...

Quantinuum has unveiled a third-generation quantum computer that could be easier to scale up than rival approaches. The US- and UK-based company Quantinuum today unveiled Helios, its third-generation ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.
