What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

For decades, quantum computing has felt like something out of science fiction — abstract, theoretical, and always “10 years away.” But in 2025, the story has changed. Quantum technology is no longer ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

Quantum theory is a mind-bending idea, suggesting that, at the subatomic level, particles can exist in multiple states at the same time. Scientists often give the example of physicist Erwin ...

One often-repeated example illustrates the mind-boggling potential of quantum computing: A machine with 300 quantum bits could simultaneously store more information than the number of particles in the ...

A quantum computer has demonstrated that it can solve a problem more efficiently than a conventional computer. This achievement comes from being able to unlock a vast memory resource that classical ...

While William Rowan Hamilton isn’t a household name like, say, Einstein or Hawking, he might have been. It turns out the Irish mathematician almost stumbled on quantum theory in the or ...

In any experiment, specifying a physical quantity of interest always relies on a reference frame. For example, identifying the time at which an event happens only makes sense relative to a clock.

Scientists have linked nuclear spins inside silicon chips, marking a leap toward scalable quantum computers. Engineers at UNSW have achieved a major breakthrough in quantum computing by creating what ...

This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the Planck length ...

If I were to flip you the bird left-handed, which I sometimes do to mix things up, you’d notice that my middle finger is crooked, with a bulged knuckle. Why does it look like that? Catfish noodling.
