An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...

A new room-temperature quantum device developed at Stanford uses twisted light and advanced materials to link photons and ...

An international team of physicists has uncovered a subtle but important twist in how “memory” works in quantum systems.

Quantum computing firm Rigetti has launched the Novera QPU, the company’s first commercially available quantum processing unit (QPU). Built at Rigetti’s Fab-1 facility in Fremont, California, the ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...

Duplicating the information held in quantum computers was thought to be impossible thanks to the no-cloning theorem, but researchers have now found a workaround ...

Imagine zooming into matter at the quantum scale, where tiny particles can interact in more than a trillion configurations at once. If that sounds complicated, it is. Physicists often rely on ...

Quantum computers use qubits, which are based on quantum physics, allowing them to solve complex problems far faster than ...

Magnetic materials in a quantum spin liquid phase are of great interest in the pursuit of exotic state of matter and quantum ...

Crystal jellyfish have an eerie beauty: thanks to a natural protein, they emit a faint green glow. For decades, researchers have used that green fluorescent protein and similar molecules to light up ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one.
