Holographic imaging of electromagnetic fields using electron-light quantum interference

In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light. Scientists can then illuminate ...

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 ...

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, ...

Physicists propose first method to control single quanta of energy

(Phys.org)—Physicists have proposed what they believe to be the first method to control the transport of energy at the level of single energy quanta (which are mostly phonons). They show that it's theoretically possible ...
