Virtual Superlensing Made a Reality

Electrical, Electronics & Instrumentation, Mechanical, Production & Manufacturing

A little bit of distance can make all the difference. That’s what two researchers at the University of Sydney Nano Institute recently concluded in their study on a new method for “superlensing,” a way of seeing things that are smaller than the wavelength of light, and doing so without any…

Two Oddball Ideas for a Megaqubit Quantum Computer

Computer & Information Technology

The perpetual problem with scaling up most quantum computers is a seemingly mundane one—too many cables. Experts say quantum computers might need at least a million qubits kept at near absolute zero to do anything computationally noteworthy. But connecting them all by coaxial cable to control and readout electronics, which…

Ultrafast Terahertz Tech Via Electronic Metadevices

Computer & Information Technology

Ultraquick telecommunications at terahertz frequencies are now possible using “electronic metadevices,” which may set the stage for the next generation of speedy gadgets. The way in which these novel devices control electric fields is similar to how invisibility cloaks manipulate light, heat, and sound, a new study finds.As electronics shrink,…
