In the world of quantum computing, interaction is everything. For computers to work at all, bits—the ones and zeros that make up digital information—must be able to interact and hand off data for processing. The same goes for the quantum bits, or qubits, that make up quantum computers. But that interaction creates a problem—in any system in which qubits […]
Ecology And AI
It’s poised to transform fields from earthquake prediction to cancer detection to self-driving cars, and now scientists are unleashing the power of deep learning on a new field – ecology. A team of researchers from Harvard, Auburn University, the University of Wyoming, the University of Oxford and the University of Minnesota demonstrated that the artificial […]
Professor Imagines ‘Free Trade’ on Energy and Environmental Issues
China and the United States, the planet’s top producers of C02, also lead the world in wind power installation. Both countries have ambitious plans to reduce carbon emissions in the coming decades and the continued development of wind power is central to those plans. However, each country is facing serious and distinct challenges in utilizing […]
Dive Of The RoboBee
In 1939, a Russian engineer proposed a “flying submarine” — a vehicle that can seamlessly transition from air to water and back again. While it may sound like something out of a James Bond film, engineers have been trying to design functional aerial-aquatic vehicles for decades with little success. Now, engineers may be one step […]
A Rechargeable Battery To Power A Home From Rooftop Solar Panels
Silicon’s Serious New Contender
Silicon has few serious competitors as the material of choice in the electronics industry. Yet transistors, the switchable valves that control the flow of electrons in a circuit, cannot simply keep shrinking to meet the needs of powerful, compact devices; physical limitations like energy consumption and heat dissipation are too significant. Now, using a quantum […]
Organic Mega Flow Battery Promises Breakthrough for Renewable Energy
A team of Harvard scientists and engineers has demonstrated a new type of battery that could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and solar far more economical and reliable. The novel battery technology is reported in a paper published in Nature on […]
‘Groovy’ hologram creates strange state of light at visible and invisible wavelengths
Nanostructured device controls the intensity, phase, and polarization of light for wide applications in optics Cambridge, Mass. – August 20, 2013 – Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated with nanoscale […]
