Scientist have spotted a strange type of quantum movement occurring in electrons travelling between the atomic layers of a material.
Instead of travelling from the top to the bottom layer through the middle, the electrons were caught disappearing from the top layer and reappearing in the bottom letter a fraction of a second later — with no trace of them existing in between.
“Electrons can show up on the first floor, then the third floor, without ever having been on the second floor,” said lead researcher Hui Zhao from the University of Kansas.
You can’t save data on a quantum computer. So a commercial one will need to use vintage tech—ultra dense hard drives, maybe made of DNA or single atoms.
Yorktown Heights, N.Y. — 06 Mar 2017: IBM (NYSE: IBM) announced today an industry-first initiative to build commercially available universal quantum computing systems. “IBM Q” quantum systems and services will be delivered via the IBM Cloud platform. While technologies that currently run on classical computers, such as Watson, can help find patterns and insights buried in vast amounts of existing data, quantum computers will deliver solutions to important problems where patterns cannot be seen because the data doesn’t exist and the possibilities that you need to explore to get to the answer are too enormous to ever be processed by classical computers.

Watson Research Center in Yorktown, NY. On Monday, March 6, IBM announced that it will build commercially available universal quantum computing systems. IBM Q quantum systems and services will be delivered via the IBM Cloud platform and will be designed to tackle problems that are too complex and exponential in nature for classical computing systems to handle. One of the first and most promising applications for quantum computing will be in the area of chemistry and could lead to the discovery of new medicines and materials. IBM aims at constructing commercial IBM Q systems with ~50 qubits in the next few years to demonstrate capabilities beyond today’s classical systems, and plans to collaborate with key industry partners to develop applications that exploit the quantum speedup of the systems.

Scientists say it’s possible to build a new type of self-replicating computer that replaces silicon chips with processors made from DNA molecules, and it would be faster than any other form of computer ever proposed — even quantum computers.
Called a nondeterministic universal Turing machine (NUTM), it’s predicted that the technology could execute all possible algorithms at once by taking advantage of DNA’s ability to replicate almost perfect copies of itself over billions of years.
The basic idea is that our current electronic computers are based on a finite number of silicon chips, and we’re fast approaching the limit for how many we can actually fit in our machines.
Researchers from The University of Manchester have shown it is possible to build a new super-fast form of computer that “grows as it computes”.
Professor Ross D King and his team have demonstrated for the first time the feasibility of engineering a nondeterministic universal Turing machine (NUTM), and their research is to be published in the prestigious Journal of the Royal Society Interface.
The theoretical properties of such a computing machine, including its exponential boost in speed over electronic and quantum computers, have been well understood for many years – but the Manchester breakthrough demonstrates that it is actually possible to physically create a NUTM using DNA molecules.
Quantum entanglement is one of the more bizarre theories to come out of the study of quantum mechanics – so strange, in fact, that Albert Einstein famously referred to it as “spooky action at a distance.”
Essentially, entanglement involves two particles, each occupying multiple states at once – a condition referred to as superposition. For example, both particles may simultaneously spin clockwise and counterclockwise. But neither has a definite state until one is measured, causing the other particle to instantly assume a corresponding state.
The resulting correlations between the particles are preserved, even if they reside on opposite ends of the universe.
