Scientists have achieved a breakthrough in analog computing, developing a programmable electronic circuit that harnesses the properties of high-frequency electromagnetic waves to perform complex parallel processing at light-speed.<\/p>\n
The discovery points to a new era of computing that operates far beyond the limits of conventional digital electronics, using less energy, while performing massive calculations.<\/p>\n
The study, “Programmable circuits for analog matrix computations<\/a>,” has been published in Nature Communications.<\/p>\n The research was led by Dr. Rasool Keshavarz from the University of Technology Sydney (UTS) and Associate Professor Mohammad-Ali Miri from Rochester Institute of Technology (RIT), with co-authors Dr. Kevin Zelaya (RIT) and UTS Associate Professor Negin Shariati, Founding Director of the Radio Frequency and Communication Technologies (RFCT) Lab.<\/p>\n “This breakthrough paves the way for next-generation analog radio frequency (RF) and microwave processors with applications in radar, advanced communications, sensors and space technologies that require real-time operations,” said Dr. Keshavarz, a Senior Research Fellow, Principal System Engineer and Technical Lead at the RFCT Lab.<\/p>\n “We’ve bridged physics and electronics to design the first programmable microwave-integrated circuit that can execute matrix transformations, a type of mathematical operation fundamental to modern technologies,” said Associate Professor Mohammad-Ali Miri.<\/p>\n Conventional digital computing is limited by factors such as transistor switching, clock speed (the speed at which a digital processor executes instructions), heat generation and energy efficiency.<\/p>\n Analog computing, in contrast, processes information directly using continuous signals like electromagnetic waves<\/a>, allowing many calculations to happen in parallel and with far less energy.<\/p>\n The potential applications are wide-ranging. Ultra-fast analog processors could power next-generation wireless networks, real-time radar and sensing for defense and space, advanced monitoring in mining and agriculture and new tools for industrial and scientific research<\/a>.<\/p>\n “By establishing a platform for scalable analog signal processing<\/a>, this collaboration positions UTS and its international partners at the forefront of a new computing paradigm, integrating device-level physics with system-level applications,” said Dr. Keshavarz.<\/p>\n “This study marks the start of a broader research trajectory. Follow-up studies are already in preparation to expand the technology toward practical system-level architectures, so that computing can move beyond digital limits.”<\/p>\n “This novel research is a great example of taking a bold concept and turning it into reality through world-class multidisciplinary collaboration,” said Associate Professor Shariati.<\/p>\n “By bringing together expertise in electronics, RF engineering, physics, and photonics across Australia and the US, the team has moved this breakthrough from theory to a working platform, paving the way for practical, next-generation computing systems.”<\/p>\n Dr. Keshavarz said the approach is fundamentally different from quantum computing.<\/p>\n “Unlike quantum systems, which face major challenges in scalability and stability, our analog computing platform is feasible today and capable of delivering real-world applications much sooner.”<\/p>\n More information: Provided by \t\t\t\t\t\t\t\t\t\t\t\t\t<\/a><\/p>\n \n Citation: \n This document is subject to copyright.
