Researchers from Regensburg and Birmingham have overcome a fundamental limitation of optical microscopy. With the help of quantum mechanical effects, they succeeded for the first time in performing ...

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means is up for interpretation. Suppose you want to empty a box. Really, truly ...

Software firm Horizon Quantum claimed it is the first private company to deploy a commercial quantum computer in Singapore. The deployment also makes it the first quantum software company to deploy ...

A century ago, the strange behavior of atoms and elementary particles led physicists to formulate a new theory of nature. That theory, quantum mechanics, found immediate success, proving its worth ...

Quantum computers based on ions or atoms have one major advantage: The qubits themselves aren’t manufactured, and there’s no device-to-device variability among atoms. Every atom is the same and should ...

The original version of this story appeared in Quanta Magazine. In 1974, five years before he wrote his Pulitzer Prize–winning book Gödel, Escher, Bach: An Eternal Golden Braid, Douglas Hofstadter was ...

Does quantum mechanics really reflect nature in its truest form, or is it just our imprecise way of describing the weird properties of the very small? A famous test that can help answer this question ...
