Generating Mono-Cycle Terahertz Pulses from Shift Currents in Asymmetric Quantum Wells

A time-dependent electric current emits an electromagnetic wave, a basic physical effect exploited in telecom antennas. Transferring this mechanism to the ultrashort length and time scales of the quantum world allows for generating intense picosecond terahertz (THz) pulses in asymmetric semiconductor quantum structures.

Optomechanical Quantum Teleportation is an Important Step Toward Hybrid Quantum Internet

Researchers at the Delft University of Technology (TU Delft) in the Netherlands and the University of Campinas (UNICAMP) in Brazil have shown that information encoded in a quantum bit (qubit) consisting of a single photon can be teleported to the mechanical motion of an optomechanical device comprising billions of atoms.

Using Quantum Systems for Generating Single Photons

After the "first quantum revolution" – the development of devices such as lasers and the atomic clock – the "second quantum revolution" is currently in full swing. Experts from all over the world are developing fundamentally new technologies based on quantum physics.

Stanford Researchers Study the Quantum Properties of Soliton Microcombs

Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a "soliton" frequency comb oscillates in unison, generating solitary pulses with consistent timing.

Closing in on the First Light in the Universe

Research using new antennas in the Australian hinterland has reduced background noise and brought us closer to finding a 13-billion-year-old signal.

Split Photons may Also Exist, Researchers Say

Nearly a century after Italian physicist Ettore Majorana laid the groundwork for the discovery that electrons could be divided into halves, researchers predict that split photons may also exist, according to a study from Dartmouth and SUNY Polytechnic Institute researchers.

Researchers Spot Young Stars at the Center of Milky Way Galaxy

What was formerly believed to be a gas and dust cloud at the center of the galaxy essentially comprises three very young stars. That is the finding of a new study carried out by researchers from the University of Cologne’s Institute of Astrophysics.
