Quantum Computing

Generating and confirming the randomness of qubits could lead to breakthroughs in computer data encryption

Quantum computing could lead to revolutions in cryptography, materials design and telecommunications. But fulfilling those promises could be many years away

Here are six ways to build a quantum computer

Sometimes science does make our world turn upside down

The rare isotope helium-3 is one of Earth’s most precious commodities—so precious, in fact, that it might prove profitable to mine from the moon

Researchers have developed a way to flip time to move backward in a quantum system. This level of control could lead to bizarre real-world applications

How the discovery of altermagnets could change physics and computing

The SciFy program tests whether adversaries’ most outlandish scientific claims add up or fall apart

Charles H. Bennett and Gilles Brassard, winners of the latest Turing Award, spent their lives touting the advantages of the quantum world

Fluorescent proteins with a quantum upgrade could offer unprecedented views inside cells

A team at IBM Research has assembled a strange new ring-shaped molecule that bends around like a more complicated Möbius strip

“Quantum echoes” rippling through Google’s quantum computer chip Willow could lead to advances in molecular chemistry and the physics of black holes
