More stable qubits in perfectly normal silicon

The power of future quantum computers stems from the use of qubits, or quantum bits, which do not have to be either 0 or 1, but can also be 0 and 1 at the same time. It is not yet clear on which technology these qubits in quantum computers will be based, but qubits based on electron spins are looking more and more promising. It was thought that these could only be produced in the expensive semiconductor material gallium arsenide, but researchers have now discovered that the more common material ...
