A groundbreaking development in quantum computing has been made by Google with a machine that performs extremely complex calculations instantaneously. Taking just moments to complete calculations that would otherwise require 47 years, the new quantum computer outperforms the world’s most advanced supercomputers. This achievement marks a significant milestone in the evolution of quantum computing technology. The principles of quantum physics are harnessed by quantum computers to offer computation speeds far beyond what classical computers can achieve. The latest quantum processor from Google, the Sycamore quantum processor, boasts an impressive 70 cubits, a substantial improvement from the previous 53 qubit version. The quantum information stored and processed by each qubit is a level of achievement that classical computers cannot match. Great promise for transforming fields such as climate science and drug discovery is held by the computational power of quantum computers.

The rapid advancement, however, of quantum computing also raises concerns about its potential to threaten existing encryption systems. The impact of quantum computers on encryption systems is considered by National security experts to be a significant challenge. Critics argue that practical applications outside of academic research are still limited, while quantum computing has made impressive strides. The computational power of quantum computers far surpasses that of classical computers, which operate based on binary code. The quantum paradigm transcends the limitations of classical computers in processing vast amounts of data. The quantum computer at Google represents a revolutionary leap in computational power and has the potential to transform various industries. The experts told The Telegraph that surpassing the capabilities of classical computers, which Google claimed to have done earlier, means achieving quantum supremacy. The CEO of quantum company Riverlane, Steve Brierley, considers Google’s achievement a major milestone in the field.
