Morocco: 'Mini fridge' for quantum computers

Cold-held Beilons can store and communicate information, bringing powerful quantum computers closer to reality. But the problem is how to maintain the cold state of Beier ion. The answer is magnesium, which can act as a mini fridge for each Be-ri ion.

' This is one of the most advanced computer systems ever, ' commented Steven Olmschenk of the University of Maryland on a quantum computer.

The quantum computer has the ability to perform complex calculations much faster than conventional computers today. They can quickly solve the complex problems that the most powerful supercomputers today take millions of years to find no solution, so they are very useful for decoding tasks. In a traditional computer, each bit of information to be stored is 0 or 1. But the quantum bits have a special storage property called a quantum superposition , meaning that each bit can be stored a lot. value 0 or 1 at the same time. Quantum superposition can give quantum computing the ability to calculate extremely fast.

In a new study, two ionic ions act as quantum bits by storing information in an internal property called spin state. The magnetic field has pushed ions to other locations inside the vacuum environment, where laser pulses perform a logical sequence of operations with Be-ri ions. For example, each quantum bit has a representational state of 0, after a laser pulse it will switch to another representational state of 1, Jonathan Home is one of the authors of the study, working at Technology and Standards Laboratory of the Royal Institution in Boulder, Colorado, USA.

David Lucas, a physicist at Oxford University in England, said: ' This is a very important development in concentrating the optimal components for quantum computer manufacturing '.

Find the Beic ion, the problem is that the ion ions need to be kept cold to maintain a stable state to work with quantum computers. Laser beams while performing logical operations will make the ions heat up, move faster, and become more chaotic. And the information stored in the spin will be lost. To solve this problem, Jonathan Home and his colleagues attached magnesium ions next to each of the ri-ions as a portable mini fridge . When ions heat up, the lasers cool down magnesium ions and these ions will cool the ion ions.

In order to test the repeatability of this system, Home and colleagues ran over and over again, using different starting conditions. The research team found that the following operation sequences also performed like the original operation sequence. This repeatability could eventually result in a more realistic and stable quantum computer, Home said.
