Protected Majorana states for quantum information
Quantum technology has the potential to revolutionise computation, cryptography and simulation of quantum systems. However, quantum physics places a new demand on information processing hardware: quantum states are fragile, and so must be controlled without being measured. Researchers at the Niels Bohr Institute have now demonstrated a key property of Majorana zero modes that protects them from decoherence.
The answer to the UK's quantum challenge is SIMPLE
A £3m grant announced by Universities and Science minister Jo Johnson has been awarded to the University of Surrey to provide the answer to the challenge of enabling solid state quantum technologies, leading to quantum computers.
A different spin on quantum computing
In what may provide a potential path to processing information in a quantum computer, researchers have switched an intrinsic property of electrons from an excited state to a relaxed state on demand using a device that served as a microwave 'tuning fork'. The team’s findings could also lead to enhancements in magnetic resonance techniques, which are widely used to explore the structure of materials and biomolecules and for medical imaging.
Quantum dot solids could develop latest era in electronics
Just as the single-crystal silicon wafer forever changed the nature of communication 60 years ago, a group of Cornell researchers is hoping its work with quantum dot solids - crystals made out of crystals - can help usher in the latest era in electronics. The team, led by Tobias Hanrath, associate professor in the Robert Frederick Smith School of Chemical and Biomolecular Engineering, has fashioned two-dimensional superstructures out of single-cr...
Chiral magnetic effect generates quantum current
Scientists at the U.S Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have discovered a new way to generate very low-resistance electric current in a new class of materials. The discovery, which relies on the separation of right- and left-'handed' particles, points to a range of potential applications in energy, quantum computing and medical imaging, and possibly even a new mechanism for inducing superconduc...
Why does the UHD standard matter for quantum dot suppliers?
Content is king. And when it comes to new display technologies this mantra certainly makes a lot of sense. After all, what would be the point of getting the latest TV on the market if you just had some old DVDs to watch? Good content is what justifies a hardware upgrade. By Dr Guillaume Chansin, Senior Technology Analyst, IDTechEx.
Will macroscopic quantum superposition get off the ground?
Researchers from Stanford University have extended the record for macroscopic quantum superposition (the idea of being in two places, or states, at once) from 1 to 54 centimeters (0.39 to 21 inches) by launching a supercooled cloud of rubidium atoms, all in the same state, 10 meters (33 feet) into the air using a laser. Their results were published in Nature.
Demand for quantum dots set to increase 20-fold
Ever since Sony launched the first television with quantum dots in 2013, these highly engineered materials have been back in the spotlight. In the new report Quantum Dots 2016-2026: Applications, Markets, Manufacturers. IDTechEx Research forecasts that shipments of quantum dots will increase significantly in the next ten years. By Guillaume Chansin, Senior Technology Analyst, IDTechEx.
Quantum physics problem proved unsolvable
A mathematical problem underlying fundamental questions in particle and quantum physics is probably unsolvable, according to scientists at UCL, Universidad Complutense de Madrid – ICMAT and Technical University of Munich. It is the first major problem in physics for which such a fundamental limitation could be proven.
Quantum computer made of semiconductor materials
Physicists at the Technical University of Munich, the Los Alamos National Laboratory and Stanford University (USA) have tracked down semiconductor nanostructure mechanisms that can result in the loss of stored information – and halted the amnesia using an external magnetic field. The new nanostructures comprise common semiconductor materials compatible with standard manufacturing processes.
