Research Breakthrough in Entanglement Could Lead to High-Dimensional Encoding of Quantum Information, Future Quantum Devices

Quantum entanglement—or what Albert Einstein once referred to as “spooky action at a distance”— occurs when two quantum particles are connected to each other, even when millions of miles apart. Any observation of one particle affects the other as if they were communicating with each other. When this entanglement involves photons, interesting possibilities emerge, including entangling the photons’ frequencies, the bandwidth of which can be controlled.

Helium: A Commodity With Increased Potential – From the Quantum Computing Industry?

South African natural gas and helium producer Renergen’s (ASX:RLT) deal with helium trader Argonon could be the catalyst to establishing more pricing transparency in the sector, the company said today. RLT has just completed a helium forward sale agreement for 100,000 units – each representing a thousand standard cubic feet (MCF) – at 99.999% purity over 19 years, to Argonon.

Getting the Output Right: Team Takes to Task Achieving Full Advantage of Quantum Computing

Quantum computers are advancing at a rapid pace and are already starting to push the limits of the world’s largest supercomputers. Yet, these devices are extremely sensitive to external influences and thus prone to errors which can change the result of the computation. This is particularly challenging for quantum computations that are beyond the reach of our trusted classical computers, where we can no longer independently verify the results through simulation. “In order to take full advantage of future quantum computers for critical calculations we need a way to ensure the output is correct, even if we cannot perform the calculation in question by other means,” says Chiara Greganti from the University of Vienna.
