A new mathematical 'blueprint' is accelerating fusion device development

Developing commercial fusion energy requires scientists to understand sustained processes that have never before existed on Earth. But with so many unknowns, how do we make sure we're designing a device that can successfully harness fusion power?

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.

Currently, 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.

Quantum computers' exponentially faster computing speeds have offered plasma and fusion scientists the tantalizing possibility of vastly accelerated fusion device development. 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. However, upgrading to a quantum computer is no simple task...

Consequently, for plasma physicists to take advantage of quantum computing's power for solving problems, classical physics must be translated into the language of quantum mechanics. The researchers tackled this translational challenge, and in their paper, they reveal that a Dyson map can bridge the translational divide between classical physics and quantum mechanics...

The paper's Dyson map and circuits have put quantum computing power within reach, fast-tracking an improved understanding of plasmas and electromagnetic waves, and putting us that much closer to the ideal fusion device design.

[Tell It Right]

Won't work. The Dims taught us that math is racist.

You must find a non-math solution. The science is settled.

[Dr. Sivana]

I am skeptical, but hungry. Where was General Saganaki?

[PerConPat]

"Dyson maps and unitary evolution for Maxwell equations in tensor dielectric media,"

Sounds good to me! What does it mean? /s

[Yo-Yo]

Oh boy, only 10 more years...

I don't know which is going to get here first, irreversible Global Warming or Fusion poweer.

[jdt1138]

I don't know how many years until we get fusion power but this scientist will be able to both solve male hair loss and prolong erections.

[aquila48]

Sounds like it’s right around the corner... AGAIN!

Here’s a video on Dyson mapping.

Fusion? There is no fuel. Fission is the future. But what the hell do I know?

[KC Burke]

Sure, now you post it but I was saying that back in the sixties.

[tet68]

Until they come up with a way to make electric power
DIRECTLY from nuclear energy, we are just back to
the same old steam technique we have used for hundreds
of years.

[blackdog]

Uninspiring talk from 50 year old white guys.

Interesting synopsis. They mention 'cold fusion' which brings back memories of endless FReeper fights over Pons-Fleischmann's work and whether it was real or a hoax.

Those were heady days...

[isthisnickcool]

Seems to me that we need a free energy source that can be harnessed. Maybe something that is explosive in nature? First, we build a submersible out of carbon fiber....

[SuperLuminal]

From reading the article in Phys Rev:
There are two steps needed to convert this equation into a unitary evolution equation. In the first step, a weighted Hilbert space is formulated in which the generator of dynamics is a pseudo-Hermitian operator. In the second step, a Dyson map is constructed which maps the weighted-physical-Hilbert space to the original Hilbert space.

This may be a classic case of plagiarism...
Seems to me that I heard Joe Biden and Josh Shapiro posing the very same algebra last week during their news conference while discussing unitary representations of the Poincare group...

[PerConPat]

LOL...The kid is brilliant...Maybe we should turn him loose on fusion energy research...
