Âé¶¹ÒùÔºicists uncover strong light-matter interactions in quantum spin liquids

Âé¶¹ÒùÔºicists have long theorized the existence of a unique state of matter known as a quantum spin liquid. In this state, magnetic particles do not settle into an orderly pattern, even at absolute zero temperature. Instead, ...

New quantum resistance standard can operate without an external magnetic field

Scientists at the University of Würzburg and the German national metrology institute (PTB) have carried out an experiment that realizes a new kind of quantum standard of resistance. It's based on the Quantum Anomalous Hall ...

Study provides experimental evidence of high harmonic generation producing quantum light

High harmonic generation (HHG) is a highly non-linear phenomenon where a system (for example, an atom) absorbs many photons of a laser and emits photons of much higher energy, whose frequency is a harmonic (that is, a multiple) ...

Study observes a phase transition in magic of a quantum system with random circuits

In the context of quantum mechanics and information, "magic" is a key property of quantum states that describes the extent to which they deviate from so-called stabilizer states. Stabilizer states are a class of states that ...
