Quantum computing could advance┬ásignificantly after news that the company┬áis working on a 50 qubit google quantum computer (quantum bits), reports New Scientist. The machine, with which Google aims to have the “quantum supremacy” would reach 50 quantum bits.

This machine could be one of the most powerful supercomputers in the world in certain areas and could reach the end of next year. While classical computers used bits are 0 or 1, the quantum bits can be 0, 1 or both (what is known as an overlay). Also read: Seven things quantum computers will do for you.

These machines can therefore take advantage of the significantly higher number of possible states, if scientists unravel how to operate these systems. Previously the organization┬áhad announced a set of 9 qubit, but the 50 qubit google quantum computer is a step in its pursuit of “quantum supremacy.”

The company plans to show that their┬ámachine can outperform existing supercomputers with the power of quantum computing. Using the 49th world’s most powerful computer, the Edison Machine US National Energy Research Scientific Computing Center, Google simulated the behavior of quantum circuits in increasingly large grids of qubits, to grids 6 x 7 of 42 qubits.

As the grid becomes larger, exponentially increasing memory requirements: A grid of 6 x 4 requires 268 megabytes, while a 6 x 7 needs 70 terabytes. A grid of 48 qubit would require 2,252 petabytes of memory, almost twice what you use the most powerful computer in the world. That’s the problem that Google hopes to solve with its 50 qubit quantum computer.
