Although quantum computing is still in its infancy, enough progress is being made for it to look a little more promising than other "revolutionary" technologies, like fusion power or flying cars. IBM, Intel, and Google all either operate or are producing double-digit qubit computers right now, and there are plans for even larger quantum computers in the future. With this amount of inertia, our quantum computing revolution seems almost certain.
Tiny quantum computers capable of performing calculations 100 million times faster than conventional computers have already been made. But scientists are having trouble scaling up these systems to a useful size for applications such as artificial intelligence (AI). Now scientists have developed the first ever'quantum bridge', which could link lots of small quantum computers together. The discovery opens up the potential to create more powerful AI systems through the development of quantum computing.

Researchers from the University of New South Wales (UNSW) have announced the results of a test they said has brought a quantum computer closer to reality. According to UNSW, the researchers have demonstrated an integrated silicon quantum bit (qubit) platform that combines both single-spin addressability, which the university explained is the ability to write information on a single spin qubit without disturbing its neighbours, and a qubit "read-out" process, which is expected to be vital for quantum error correction. "Moreover, their new integrated design can be manufactured using well-established technology used in the existing computer industry," UNSW added. Quantum computers will require millions of connected and integrated qubits and the tests completed by the researchers have proven it is possible to correct the errors that occur in fragile quantum systems. There are five leading hardware configurations for a quantum computer, and scientists the world over are trying to determine which is going to be the winner.
Take one atom of the element antimony, use an ion beam to shoot it into a silicon substrate, and you just may be on your way to building a working quantum computer. That's according to researchers at Sandia National Laboratories, who announced this week that they've used that technique with promising results. In their experiment, described in the journal Applied Physics Letters, the researchers used an ion beam generator to insert the antimony atom into an industry-standard silicon substrate -- a process that took just microseconds. That atom, equipped with five electrons, carries one more than a silicon atom does. Because electrons pair up, the odd antimony electron remains free.
