Magnetism generated in non-magnetic metals

By - August 10, 2015
By subtly altering certain quantum interactions in matter, scientists from the University of Leeds have shown for the very first time how to generate magnetism in metals that aren’t normally magnetic. Synthetic magnets made using this technique may one day reduce our reliance on rare or toxic metals in such things as wind turbines, computer hard drives and magnetic field medical imaging devices.

Robobug: Scientists clad bacterium with graphene to make a working cytobot

By - March 25, 2015
By cladding a living cell with graphene quantum dots, researchers at the University of Illinois at Chicago (UIC) claim to have created a nanoscale biomicrorobot (or cytobot) that responds electrically to changes in its environment. This work promises to lay the foundations for future generations of bio-derived nanobots, biomicrorobotic-mechanisms, and micromechanical actuation for a wide range of applications. Read More

Cesium atoms get a shake-up to create excitation in superfluid

By - February 24, 2015
Helium-4 superfluid is a fascinating substance. With properties that seemingly defy normal physics, it leaks straight through glass, bubbles up out of containers, flows around objects and even climbs up walls. As if superfluid helium-4 was not strange enough, in 1941 it was also predicted that it should contain an exotic, particle-like excitation – a quasiparticle – called a roton. After many years of trying to verify this prediction, researchers at the University of California now claim to have successfully created a roton structure in an atomic superfluid of cesium-133.

New micro-ring resonator creates quantum entanglement on a silicon chip

By - January 28, 2015
The quantum entanglement of particles, such as photons, is a prerequisite for the new and future technologies of quantum computing, telecommunications, and cyber security. Real-world applications that take advantage of this technology, however, will not be fully realized until devices that produce such quantum states leave the realms of the laboratory and are made both small and energy efficient enough to be embedded in electronic equipment. In this vein, European scientists have created and installed a tiny "ring-resonator" on a microchip that is claimed to produce copious numbers of entangled photons while using very little power to do so.

Quantum memory storage to help quantum communications go the distance

By - November 30, 2014
The technologies made possible by breakthroughs in quantum physics have already provided the means of quantum cryptography, and are gradually paving the way toward powerful, practical, everyday quantum computers, and even quantum teleportation. Unfortunately, without corresponding atomic memories to appropriately store quantum-specific information, the myriad possibilities of these technologies are becoming increasingly difficult to advance. To help address this problem, scientists from the University of Warsaw (FUW) claim to have developed an atomic memory that has both exceptional memory properties and a construction elegant in its simplicity.

Researchers achieve long-distance light to matter quantum teleportation

By - September 22, 2014
A successful test in passing information from light into matter – using the teleportation of the quantum state of a photon via optical fiber cable to a receiving crystal located over 25 km (15 mi) away – has been claimed by physicists at the University of Geneva. This test shattered the same team’s previous record and may herald the development of greater, long-distance teleportation techniques and qubit communications and computing capabilities. Read More

Super-secure quantum-based data encryption for everyone

By - September 5, 2014
With a new device set to make unbreakable, quantum-based cryptographic security available for everyone for the very first time, ordinary people will be able to use cryptographic systems that – until recently – only existed as experiments in the most advanced physics laboratories. Developed at the Los Alamos National Laboratory (LANL) the device incorporates the quantum mechanics of random photon polarization to generate random numbers and create cryptographic keys. Read More
