Information can be stored in the nucleus of the atom
The objects of quantum mechanics, such as elementary particles, can simultaneously be in two mutually exclusive states. A bit, the minimum unit of information capable of taking the value "1" or "0", in quantum computers turns into a quantum bit, a qubit, which can be zero and one at a time.
Scientists have been experimenting for a long time, trying to find a way to control quantum bits. The key task is to isolate the quantum bit from the information noise of the environment in order to protect the information contained in it, while still being able to measure and change its state. This week a team of scientists from the UK and the USA published a solution to this problem in the journal Nature.
Scientists have described a system that uses an electron and the nucleus of a phosphorus atom enclosed in a silicon crystal. The electron and atomic nucleus in this system become tiny quantum "magnets" capable of storing quantum information. Information is changed and read through manipulations with an electron; the nucleus acts as a repository.
')
Experiments have shown that the lifetime of information stored in such a system is about 1 seconds. This is a significant breakthrough, since the storage time of quantum information in previous experiments did not exceed a tenth of a second. Other researchers have proven that if a quantum system can store information for more than a second, error correction technology will allow the state of quantum data to be saved for an unlimited time.
From myself: it will be interesting to look at the volume of the “typical bar” of memory working on this principle.
