Personally, however, I don't think we will feel the effects of quantum computers in everyday life in the next ten years. So far, no existing quantum computer is powerful enough to compete with a conventional computer. The problem is that the quantum states we want to control are incredibly fragile and therefore prone to interference. A few qubits can be controlled well, but with millions of qubits, it's a phenomenal challenge. So scalability is an issue.
The second question is how quantum computers will be noticeable in everyday life once they are here. Many people think that we will then carry quantum computers in our pockets or that the new gaming computer will be based on quantum technology. It is possible that quantum computers will be used by everyone, just like classic computers, but this is not foreseeable at present.
Although quantum computers can do everything that classic computers can do and more, the extra capabilities of quantum computers come with a technical overhead. This means that standard calculations are much slower on quantum computers.
