Google achieves 'quantum supremacy', builds a computer 'Sycamore'

Google researchers have announced that they have achieved "quantum supremacy" by building a quantum computer that performs a task practically no classical computer can. The 54-qubit computer 'Sycamore' conducted a task in 200 seconds that would take the world's fastest supercomputer 10,000 years, researchers said.

 

The scientific journal Nature has also published the results of Google’s efforts to build a quantum computer that can perform a task that no classical computer can; this is known in the field as “quantum supremacy.” Sycamore has performed a computation in 200 seconds that would take the world’s fastest supercomputer 10,000 years.

 

This achievement is the result of years of research and the dedication of many people. It’s also the beginning of a new journey - figuring out how to put this technology to work. Google is working with the research community and have open sourced tools to enable others to work to identify new applications.

 

In the binary language, conventional electronics work on only 0s and 1s (known as bits). In quantum computers, the rules are completely different. These rules belong to Physics, which govern the microscopic world and include electrons and photons, invisible to the naked eye.

 

Additionally, unlike a conventional computer that stores data in bits, quantum computers will store data in the qubit (quantum bits). While bits can only store in either 1 or 0, qubit can store a combination of both at the same time through a phenomenon called superposition. Superposition, which deals with microscopic particles qubits, helps a computer’s performance grow exponentially. If one measures one qubit in a system of two qubits, they will know the value of second qubit measurement within seconds, and so on.

 

Google is looking forward to building “a fault-tolerant quantum computer” at the earliest. This computer would help them look into applications like lightweight batteries for cars and airplanes.
