![]() ![]() In contrast, quantum effects that influence atomic and subatomic scales are averaged out in classical plasma physics.įurthermore, the descriptive limitations of quantum mechanics aren’t suited to plasma. A plasma (which is the “dielectric media” referenced in the paper’s title) consists of many particles - electrons and ions - the collective behaviors of which are effectively described using classic statistical physics. Quantum computers excel at simulating quantum physics phenomena, but many topics in plasma physics are predicated on the classical physics model. ![]() Ram, a research scientist at the MIT Plasma Science and Fusion Center (PSFC), and his co-authors Efstratios Koukoutsis, Kyriakos Hizanidis, and George Vahala present a framework that would facilitate the use of quantum computers to study electromagnetic waves in plasma and its manipulation in magnetic confinement fusion devices. ![]() In a paper, “ Dyson maps and unitary evolution for Maxwell equations in tensor dielectric media,” recently published in Physics Review A, Abhay K. However, upgrading to a quantum computer is no simple task. Quantum computers could reconcile a fusion device’s many design parameters - for example, vessel shape, magnet spacing, and component placement - at a greater level of detail, while also completing the tasks faster. Quantum computers’ exponentially faster computing speeds have offered plasma and fusion scientists the tantalizing possibility of vastly accelerated fusion device development. We can fill gaps in our understanding using computational tools like algorithms and data simulations to knit together experimental data and theory, which allows us to optimize fusion device designs before they’re built, saving much time and resources.Ĭurrently, classical supercomputers are used to run simulations of plasma physics and fusion energy scenarios, but to address the many design and operating challenges that still remain, more powerful computers are a necessity, and of great interest to plasma researchers and physicists. But with so many unknowns, how do we make sure we’re designing a device that can successfully harness fusion power? Developing commercial fusion energy requires scientists to understand sustained processes that have never before existed on Earth. ![]()
