Novel breakthrough brings quantum computers closer to reality

Washington, August 3 (ANI): Scientists at the University of Bristol (UK) have developed a novel technique whereby the circuits are simplified to crack complex quantum algorithms, paving the way for building a quantum computer.

Dr Xiao-Qi Zhou and colleagues believe their technique will find applications across quantum information technologies, including precision measurement, simulation of complex systems, and ultimately a quantum computer – a powerful type of computer that uses quantum bits (qubits) rather than the conventional bits used in today’s computers.

Unlike conventional bits or transistors, which can be in one of only two states at any one time (1 or 0), a qubit can be in several states at the same time and can therefore be used to hold and process a much larger amount of information at a greater rate.

“The new approach we report here could be the most important development in quantum information science over the coming years,” said Professor Jeremy O’Brien, director of the Centre for Quantum Photonics.

“It provides a dramatic reduction in quantum circuit complexity – the major barrier to the development of more sophisticated quantum algorithms,” he added.

The study has been published in Nature Communications. (ANI)
