Another step on the long road to quantum computing

IBM has got error detection working on a segment of quantum computer. The firm is working towards ‘surface code’ error correction for superconducting quantum computers, which need correction because entangled qubits (quantum bits) are prone to spontaneous errors.  Surface code correction spreads quantum information across many qubits that only interact…

Little robots pull more than 100 times their weight

Mighty things come in small packages. The little robots in the video below can haul things that weigh over 100 times more than themselves. The super-strong bots – built by mechanical engineers at Stanford University in California – will be presented next month at the International Conference on Robotics and Automation…

Graphene helps study other 2D semiconductors

Researchers have used graphene and 2D insulator boron nitride to make a clean environment in which to study other 2D semiconductors. Molybdenum disulphide has come out of the tests well. At issue is the large surface area of 2D molecules which offeres huge possibilities for unwanted interaction. In work at…

Polysilicon-on-paper for printing low-cost circuits

Polysilicon can be made on paper and other low-temperature substrates by a process developer by researchers in The Netherlands and Japan. The same process has yielded CMOS transistors on a wafer. Silicon has already been used as an alternative to organic and oxide semiconductor materials in inks for printing…

Proto-quantum computer addresses Boson sampling

Quantum computers should theoretically outpace ordinary ones, but attempts to build a speedy quantum machine have so far come up short. Now an approach based on a Victorian counting device seems to be getting close. This proto-quantum computer can only solve one problem. But that problem, called boson sampling…

Microphone harvests acoustic energy to top up its charge

Researchers in America have developed a postage stamp-sized microphone that can harvest acoustic energy to top up your charge on the go. Zhong Wang of the Georgia Institute of Technology in Atlanta and his colleagues created their microphone from a thin sheet of paper just a few centimetres across…

Tiny thumb trackpad is wireless

For wireless control when hands are full, MIT has invented a thumbnail trackpad called NailO. Stroking it in different directions transmits mouse-like commands to PCs and phones. Even though it sticks on like an artificial nail, packed into the prototype are capacitive sensors, a battery, a microcontroller, and chips…

Double walled carbon nanotubes allow bandgap tuning

Mathematicians at Rice University in Texas have delved into the possible behaviour of double-walled carbon nanotubes and found a potential bandgap. Carbon nanotubes are not one thing. Instead, characteristics including tube diameter and the amount of twist in the atomic lattice along the tubular molecule are variables. One simple…
