The ultimate goal of quantum information science is to develop a quantum computer, a fully-fledged controllable device which makes use of the quantum states of subatomic particles to store information. As with all quantum technologies, quantum computing is based...
Everyone knows that water freezes at 0 degrees C. Life on Earth would be vastly different if this were not so. However, water's cousin, silica, exhibits wayward behavior when cooled that has long puzzled scientists. Unlike water, silica (SiO2) does...
A silicon-based quantum computing device could be closer than ever due to a new experimental device that demonstrates the potential to use light as a messenger to connect quantum bits of information -- known as qubits -- that are...
Researchers have designed a new LED-based train headlight that uses a tenth of the energy required for headlights using conventional light sources. If operated 8 hours every day, the electricity savings of the new design would reduce emissions of...
Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution". In quantum communication, the participating parties can detect any attempt at eavesdropping by resorting to the fundamental principle of quantum...
Producing the perfect color images we need and love often requires multiple, heavy lenses so that each color focuses in exactly the same plane. Now Penn State engineers have developed a new theory that solves the problem using a...
Operation of modern-day technology requires an ever-increasing use of broadband frequency signals. This, in turn, has grown the demand for reliable, efficient methods of signal transmission that prevent interference and are more efficient in their use of the scarcely...
Some powerful rulers of the world may dream of the possibility to get in touch with their colleagues on different continents unnoticed by friends or foes. Someday, new quantum technologies could allow for making these wishes come true. Physicists...
By hitting electrons with an ultra-intense laser, researchers have revealed dynamics that go beyond 'classical' physics and hint at quantum effects. Whenever light hits an object, some of the light scatters back from the surface of the object. However, if...
To build more aerodynamic machines, researchers are drawing inspiration from an unlikely source: the ocean. A team of evolutionary biologists and engineers at Harvard University, in collaboration with colleagues from the University of South Carolina, have shed light on a...
An off-the-wall new study by Brown University researchers shows that terahertz frequency data links can bounce around a room without dropping too much data. The results are good news for the feasibility of future terahertz wireless data networks, which...
