Researchers Develop Novel Switch to Help Scientists Build Quantum Information Transmitter Networks

Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists at MIT and Harvard University have developed a new method for connecting particles — one that could help in the development of powerful quantum computing systems. [More]
Waveguides Coupled with Surface Plasmons Hold Promise for Quantum Computing

Waveguides Coupled with Surface Plasmons Hold Promise for Quantum Computing

For years, researchers have been interested in developing quantum computers—the theoretical next generation of technology that will outperform conventional computers. Instead of holding data in bits, the digital units used by computers today, quantum computers store information in units called "qubits." One approach for computing with qubits relies on the creation of two single photons that interfere with one another in a device called a waveguide. [More]
Quantum Cryptography Could be Deployed in a Real Communications Network

Quantum Cryptography Could be Deployed in a Real Communications Network

Secure mobile communications underpin our society and through mobile phones, tablets and laptops we have become online consumers. The security of mobile transactions is obscure to most people but is absolutely essential if we are to stay protected from malicious online attacks, fraud and theft. [More]
Metamaterials and Quantum Cascade Structures Combined to Create Ultra-Thin Light Detectors

Metamaterials and Quantum Cascade Structures Combined to Create Ultra-Thin Light Detectors

Subtle interactions of electrons and light make them so valuable for technology: ultra-thin systems of semiconductor layers can turn electrical voltage into light. But they can also be used the other way around and serve as light detectors. [More]
Quantum Networks in Quantum Optics to be Presented at University of Virginia Hoxton Lecture

Quantum Networks in Quantum Optics to be Presented at University of Virginia Hoxton Lecture

Opportunities for the exploration of physical systems that have not, thus far, existed in the natural world – that’s what H. Jeff Kimble, William L. Valentine Professor and Professor of Physics at the California Institute of Technology, will discuss in a talk formally titled “Quantum Networks in Quantum Optics.” [More]

Hubble's Infrared Vision Captures Churning Region of Star Birth to Celebrate 24th Anniversary

In celebration of the 24th anniversary of the launch of NASA's Hubble Space Telescope, astronomers have captured infrared-light images of a churning region of star birth 6,400 light-years away. [More]
Electrons Use Quantum Mechanical Trick to Slip through Insulating Barrier

Electrons Use Quantum Mechanical Trick to Slip through Insulating Barrier

The first room-temperature light detector that can sense the full infrared spectrum has the potential to put heat vision technology into a contact lens. [More]
Attosecond Technology May Help Extend Domain of Electron Metrology into Optical Frequency Range

Attosecond Technology May Help Extend Domain of Electron Metrology into Optical Frequency Range

Light waves have the potential to boost the efficiency of conventional electronics by a factor of 100,000. In a review article that appears in “Nature Photonics” on March 14th, Prof. Ferenc Krausz of the Laboratory for Attosecond Physics (LAP) at the Max-Planck-Institut für Quantenoptik and the Ludwig-Maximilians-Universität München and his co-author Prof. Mark Stockman of Georgia State University (GSU) in Atlanta describe how this vision may one day come true.
