Superconductivity. Intrinsic abilities. Alchemy. Being.
Scientists activated the intrinsic ability of graphene to superconduct (carry an electrical current with no resistance). Before that, superconductivity in graphene has only been achieved by doping it with, or by placing it on, a superconducting material - a process which can compromise some of its other properties. But in the study (published on January),…

Synchronizing things… That are already in sync…
Scientists have set up the world's most precise 'metronome' for a kilometer-wide network. The timing system synchronizes a 4.7-kilometer-long laser-microwave network with 950 attoseconds precision. An attosecond is a millionth of a millionth of a millionth of a second. (1) Impressive. Or so it seems. Because the problem is not synchronization per se. Everything is…

Memories. For ever (changing)…
Conventional memories used in today's computers only differentiate between the bit values 0 and 1. In quantum physics, however, arbitrary superpositions of these two states are possible. Most of the ideas for new quantum technology devices rely on this "Superposition Principle". One of the main challenges in using such states is that they are usually…

Non magnetism. Magnetism. Unicorn.
Scientists have demonstrated for the first time how to generate magnetism in metals that aren't naturally magnetic, which could end our reliance on some rare and toxic elements currently used. Researchers detail a way of altering the quantum interactions of matter in order to 'fiddle the numbers' in a mathematical equation that determines whether elements…

Quantum computers. Environment. Memories. Stability. (through change)
Before the dream of quantum computing is realized, a number of inherent problems must first be solved. One of these is the ability to maintain a stable memory system that overcomes the intrinsic instability of the basic unit of information in quantum computing – the quantum bit or "qubit". To address this problem, Physicists working…
