Experts believe that in the coming years, quantum computers will replace classical computers on our desks and revolutionize our lives. They are expected to accelerate machine learning, solve climate change, and discover new drugs. Progress toward fully capable and practical quantum computers is rapidly advancing. Google researchers have recently announced their latest results, marking a significant step forward in the capabilities of current machines. Running quantum computers requires ultra-specialized and unique conditions, but despite these limitations, the computing power of quantum computers is becoming increasingly impressive.
Google claims that by achieving “quantum supremacy”, it has reached an important milestone in the production of such devices. The tech giant says it has developed a quantum computer that can perform calculations that would take the fastest classical computer 47 years in an instant. According to Google, the latest version of the Sycamore quantum processor operates with 70 qubits, surpassing the previous version, which had 53 qubits. A quantum processor with 70 qubits means it can store and process 70 quantum bits of information, which is impossible for a classical computer, regardless of its speed.
The ultimate goal is to build a commercial quantum computer that can be purchased by the public. Since this goal is still 10-20 years away, companies are currently producing experimental quantum computers that are still in the research and development phase.
