Computers With Light-Speed Capabilities

Imagine a world where data can be processed at the speed of light, where complex calculations are completed in a fraction of a second - a new type of computer that uses light rather than electricity could perform calculations faster, using less energy and less space.

This is no longer just a dream, but a promising reality that is within reach. Now, scientists have now recently created a reprogrammable light-based processor, a world-first, that they say could usher in a new era of quantum computing and communication.

Technologies in these emerging fields that operate at the atomic level are already realising big benefits for drug discovery and other small-scale applications. In the future, large-scale quantum computers promise to be able to solve complex problems that would be impossible for today's computers.

Lead researcher Professor Alberto Peruzzo from RMIT University in Australia said the team's processor, a photonics device that uses light particles to carry information, could help enable successful quantum computations by minimizing "light losses."

"Our design makes the quantum photonic quantum computer more efficient in terms of light losses, which is critical for being able to keep the computation going," said Peruzzo, who heads the ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) node at RMIT. "If you lose light, you have to restart the computation."

Other potential advances included improved data transmission capabilities for "unhackable" communications systems and enhanced sensing applications in environmental monitoring and health care, Peruzzo said.

The team reprogrammed a photonics processor in a range of experiments, achieving a performance equivalent to 2,500 devices, by applying varying voltages. Their results and analysis are published in Nature Communications."This innovation could lead to a more compact and scalable platform for quantum photonic processors," Peruzzo said.

Computers with light-speed capabilities represent a promising leap forward in the world of technology. As researchers continue to push the boundaries of what is possible, we can look forward to a future where data is processed at the speed of light.
