Âé¶¹ÒùÔºicists propose perfect material for lasers

Weyl semimetals are a recently discovered class of materials in which charge carriers behave the way electrons and positrons do in particle accelerators. Researchers from the Moscow Institute of Âé¶¹ÒùÔºics and Technology and ...

Phonon-mediated quantum state transfer and remote qubit entanglement

Quantum information platforms are based on qubits that talk to each other and photons (optical and microwave) are the carrier of choice—to date, to transfer quantum states between qubits. However, in some solid-state systems, ...

An atom in a cavity extracts highly pure single photons from weak laser light

Quantum physicists can now distil a kind of photon schnapps. When spirits are distilled, the alcohol content increases relative to the water content. A similar method developed by a team from the Max Planck Institute of Quantum ...
