    Spray-on memory could enable bendable digital storage

    Duke University researchers have developed a new ‘spray-on’ digital memory (upper left) that could be used to build programmable electronic devices on flexible materials like paper, plastic or fabric. To demonstrate a simple application of their device, they used their memory to program different patterns of four LED lights in a simple circuit. Credit: Matthew Catenacci ==

    USB flash drives are already common accessories in offices and college campuses. But thanks to the rise in printable electronics, digital storage devices like these may soon be everywhere—including on our groceries, pill bottles and even clothing...

    Nanomagnets for Future Data Storage

    The idea is intriguing: if only a single atom or small molecule was needed for a single unit of data (a 0 or a 1 in the case of binary digital technology), massive volumes of data could be stored in the tiniest amount of space. This is theoretically possible, as certain atoms can be magnetised in only one of two possible directions: “spin up” or “spin down.” Information could then be stored and read by the sequence of the molecules’ magnetisation directions.

    However, several obstacles still need to be overcome before single-molecule magnet data storage becomes a reality...

    Graphene-based electrode prototype, inspired by fern leaves, could be the answer to solar energy storage challenge. Inspired by an American fern, researchers have developed a groundbreaking prototype that could be the answer to the storage challenge still holding solar back as a total energy solution. The new type of electrode created by researchers from RMIT University in Melbourne, Australia, could boost the capacity of existing integrable storage technologies by 3000%.

    But the graphene-based prototype also opens a new path to the development of flexible ...

    Quantum Communication: How to Outwit noise

    March 31, 2017, Categories  Physics, Technology/Electronics

    Sketch of a thermal quantum network, where two nodes (for example, two superconducting qubits located inside separated dilution refrigerators) are connected via a unidirectional quantum communication channel at finite temperature T ch . (b) For the implementation of a noise-resilient transfer protocol, the qubit state is first mapped onto an intermediary oscillator. The oscillator is then coupled to the incoming and outgoing fields of the channel, f in , i ( t ) and f out , i ( t ) , via a tunable decay rate γ i ( t ) , which can be realized, for example, by a flux-tunable quantum interference device [45, 46, 47].
