A theoretical proposal offers a technique for storing an x-ray photon and releasing it with its quantum properties fully intact.

A semiconductor chip that generates entangled photon pairs is friendlier to integration with other chip-based quantum components than any previous device.

Connecting futuristic photonic crystals with conventional fiber optics may be possible with modifications at the surface.

Researchers have detected rare instances of photons splitting in two.

A new technique allows sorting of single photons according to their orbital angular momentum–a property that could serve as an alphabet for optical messages.

Microscopic pinholes may soon allow the one-by-one transfer of photons in a way that mimics the process of Coulomb blockade of electrons.

Photons normally ignore one another, but under the right conditions they might collide.

Periodic lattices called photonic band gap structures may replace traditional microwave resonators in radar, satellites, and cell phones.

Surface waves involving metallic electrons and light can be guided along a channel cut through a periodic structure.

Laser photons are great for transmitting quantum information but hard to store. A new theory describes how photon information could be transferred to clouds of atoms in a future quantum computer.

A new material using liquid crystals could be the basis for programmable optical circuits.
