How to extract information from “frozen” computers
Representatives of the Institute of science and technology in Austria have developed a prototype device to combine the information on the calculation of quantum computers with the usual. In the future the technology may allow you to create the first working quantum computer, writes the Chronicle.info with reference to NV.
The key problem of quantum computers remains extremely low temperatures at which the particles of superconducting materials can go into the quantum state and produce the necessary electrical impulses.
Quantum computation can be performed in temperature conditions close to absolute zero (minus 273 degrees Celsius), but in order to obtain data on the results of these calculations need to connect the superconductors to ordinary computers, which, of course, can’t work at such low temperatures.
Therefore, scientists worldwide are looking for a way to get information from “frozen” quantum computers and digitize it in a common electronic systems.
A possible solution has recently introduced physics from the Institute of science and technology in Austria. As stated in the press release, the Institute research group of Professor Johannes Fink used the “mechanical generator to create intricate radiation quantum computers”.
In fact, the opening for quantum entanglement phenomena in quantum mechanics, which provides that in a pair of entangled particles at any distance instantly know the characteristics of one of them, defining the current state of the other particle.
Scientists from the group of Professor Fink came to the conclusion that in a confused state can be not only particles, but also the radiation of these particles. “Imagine a box with two holes. If the holes are messed up, it is possible to describe the radiation emerging from a hole, looking for more,” explain the authors.
It is reported that the complicated radiation already described earlier, but in a recent experiment physicists from Austria for the first time used a mechanical object to experiment with this phenomenon. With the help of silicon radiation source, a length of 30 micrometres, scientists confirmed the existence of complicated radiation, which theoretically can mean exchanging information at a distance.
Because on a microscopic scale particles are amenable to the laws of quantum mechanics, the silicon source in fact allows to determine the irradiance properties of their entangled pairs of particles.
In the future, this technology may allow to combine the radiation microwave pulses in quantum computing with microwave pulses already tamed us fiber optic. This means that between the superconductors in quantum computers and devices that transmit information at room temperature it is possible to connect and read the data.
Something like quantum Wi-Fi, where the role of the router acts as a new silica source radiation physicists from Austria, with which we will be able to extract data from the cold world of quantum computing.
The authors also say that, in addition to quantum computers, their performance may improve gravitational wave detectors. With the help of his “silicon oscillator” scientists plan to learn how to determine the quantum nature of gravitational fields, which hypothetically may lead to the description of the theory of everything.
