Quantum computing relies on the laws of quantum mechanics to process vast amounts of information and calculations simultaneously, with far more power than current computers.
However, development of quantum computers has been limited as researchers have struggled to find a reliable way to increase the power of these systems, a power measured in Q-Bits.
Previous attempts to find the elusive Majorana particle have been very promising but have not yet provided definitive and conclusive evidence of its existence.
Now, researchers from the University of Surrey and the Ben-Gurion University in Israel believe they have uncovered a key method for detection of the Majorana particle, potentially enabling reliable Q-Bits to be developed.
This new research proposes using photons (particles of light) and super-conducting circuits to probe and measure semiconductor nanowires, where it is thought these particles exist at certain controlled conditions. If the particles are present, they will be revealed through a specific pattern with microwave spectroscopy.
Currently the most powerful quantum computer in existence has a power of eight Q-Bits. Once the particle is confirmed, researchers believe it will enable functioning topological Q-Bits to be produced, breaking the barriers on the way to scaling up quantum computation to many Q-Bits.
"We know what we are looking for, we just haven't found it yet - it's the ultimate physics treasure hunt! We are confident that the method we are proposing will bring us closer to unlocking the untapped potential of quantum computing in areas such as code breaking, complicated mathematical problem-solving and scientific simulation of advanced materials" said lead-author Dr Eran Ginossar, the University of Surrey.
The new method has attracted the interest of leading experimental groups and it is hoped that the new method will be trialled within the next year.
Quantum computing is one pillar of quantum technology, an area where the UK is posed to make a large investment. Last year the government announced funding of £270million for the development and application of this technology.

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
