Recent milestones inch us closer to a useful quantum computer

Despite all the hype about quantum computers, they are still too error-prone for practical use. However, recent experiments have shown that this is not always the case, lending credence to claims by companies such as Google and IBM that useful quantum computers may become a reality as early as 2029. are. These latest experiments are important milestones and indicate that we are entering a new era. Researchers say they are older.

“Suddenly, really useful devices look appealingly close to you in a way that never before,” says Jamie…
