Emergent magnetic monopoles isolated using quantum-annealing computer
LOS ALAMOS, N.M., July 15, 2021 (GLOBE NEWSWIRE) — Using a D-Wave quantum-annealing computer as a testbed, scientists at Los Alamos National Laboratory have shown that it is possible to isolate so-called emergent magnetic monopoles, a class of quasiparticles, creating a new approach to developing “materials by design.”
“We wanted to study emergent magnetic monopoles by exploiting the collective dynamics of qubits,” said Cristiano Nisoli, a lead Los Alamos author of the study. “Magnetic monopoles, as elementary particles with only one magnetic pole, have been hypothesized by many, and famously by Dirac, but have proved elusive so far.”
They realized an artificial spin ice by using the superconducting qubits of the quantum machine as a magnetic building block. Generating magnetic materials with exotic properties in this way is ground-breaking in many ways. Their process used Gauss’s law to trap monopoles, allowing the scientists to observe their quantum-activated dynamics and their mutual interaction. This work demonstrates unambiguously that magnetic monopoles not only can emerge from an underlying spin structure, but can be controlled, isolated and studied precisely.
“It was shown in the last decade or so that monopoles can emerge as quasiparticles to describe the excitation spin ices of various geometries. Previously, the National High Magnetic Field Laboratory’s Pulsed Field Facility here at Los Alamos was able to ‘listen’ to monopole noise in artificial spin ices. And now, utilizing a D-Wave quantum annealing system, we have enough control to actually trap one or more of these particles and study them individually. We saw them walking around, getting pinned down, and being created and annihilated in pairs of opposite magnetic charge. And we could thus confirm our quantitative theoretical predictions, that they interact and in fact screen each other,” said Nisoli.
“D-Wave’s processors are designed to excel in optimization, but can also be used as quantum simulators. By programming the desired interactions of our magnetic material into D-Wave’s qubits, we can perform experiments that are otherwise extremely difficult,” said Andrew King, director of Performance Research at D-Wave and an author on the paper. “This collaborative, proof-of-principle work demonstrates new experimental capabilities, improving the power and versatility of artificial spin ice studies. The ability to programmatically manipulate emergent quasiparticles may become a key aspect to materials engineering and even topological quantum computing; we hope it will be foundational for future research.”
Nisoli added, “We have only scratched the surface of this approach. Previous artificial spin ice systems were realized with nanomagnets, and they obeyed classical physics. This realization is instead fully quantum. To avoid leapfrogging we concentrated so far on a quasi-classical study, but in the future, we can really crank up those quantum fluctuations, and investigate very timely issues of decoherence, memory, quantum information, and topological order, with significant technological implications.”
“These results also have technological consequences particularly relevant to DOE and Los Alamos, specifically in the idea of materials-by-design, to produce future nanomagnets that might show advanced and desirable functionality for sensing and computation. Monopoles, as binary information carriers, can be relevant to spintronics. They also contribute significantly to Los Alamos D-Wave investments,” noted Alejandro Lopez-Bezanilla of Los Alamos, who works on the D-Wave processor and assembled the team.
Nisoli, moreover, suggests that beside fruitful applications, these results could perhaps also provide food for thought to fundamental physics:
“Our fundamental theories of particles are parametrized models. One wonders: what is a particle? We show here experimentally that not only particles but also their long-range interactions can be a higher-level description of a very simple underlying structure, one only coupled at nearest-neighbors. Could even ‘real’ particles and interactions that we consider fundamental, such as leptons and quarks, instead be construed as an emergent, higher-level description of a more complex lower-level binary substratum, much like our monopoles emerging from a bunch of qubits?”

Solar EV Charging to Bypass the Grid: A US$2.5 Billion Market by 2034, Says IDTechEx
Unreliable and fossil fuel-intense electrical grids
BOSTON, May 6, 2024 /PRNewswire/ — Electrification of cars, buses, and trucks drastically reduces CO2 emissions at the point of use compared to a diesel or petrol alternative. The adoption of EVs across all sectors, with IDTechEx predicting over 180 million electric vehicles to be sold annually by 2044. This will contribute to a drastic reduction in tailpipe emissions. However, the overall emissions are usually highly dependent on the energy mix that goes into grid electricity production. In many economies, this contains significant amounts of fossil fuels such as coal and natural gas. Beyond CO2 emissions, some grids are already at capacity, and the increased load of an electric transport sector risks blackouts and power supply issues. South Africa is an EV market with both of these issues, and several innovations have been made using distributed power generation to tackle these challenges. IDTechEx’s research report, “Off-Grid Charging For Electric Vehicles 2024-2034: Technologies, Benchmarking, Players and Forecasts”, explores the challenges and solutions associated with charging EVs in the context of constrained electricity grids.
The South African utility grid is subject to frequent load-shedding, periods when demand exceeds supply, and utility operators are forced to impose rolling black or brownouts of up to 50% capacity. This is a problem for all forms of domestic and industrial electrical use but becomes an especially pronounced problem for commercial EV operators. Fleet operators often must charge at predesignated times to maximize uptime and complete all planned routes. If the grid fails during a charging spot, the entire schedule may be adversely affected by factors beyond an operator’s control. This is an unusual grid situation; however, it presents a possible worst-case scenario for grid-congested and EV-saturated regions. In 2022, a heatwave in California prompted the state government to ask EV owners not to charge to conserve energy. The growth in electric vehicle sales will only make such problems more widespread.
South Africa also has a very carbon-intensive energy mix, with approximately 70% of power generation being from coal. This directly translates into higher lifecycle CO2 emissions from EVs powered by the electrical grid. Whilst South Africa has a particularly fossil fuel energy mix, the source of electricity plays a critical role in the lifecycle emissions of an electric vehicle.
Disturbed generation gives renewable and grid-independent electricity
One possible solution being trialed in South Africa, amongst other places, is harnessing distributed renewable microgrids to form the backbone of charging networks. By integrating a solar farm, large-scale energy storage (ES), and high-powered charging outlets, Vrendal-based Zero Carbon Charge plans to build an etruck charging network. Not only does this decouple charging from an unreliable grid, it also avoids placing excess electrical demand on utilities, avoids the need for costly grid expansions, and provides free and 100% renewable energy for the trucks to operate on. This is not limited to South Africa; the USA, in particular, has also seen a boom in companies offering grid-free solar-powered charging. In the US, many of the products are smaller scale and transportable, allowing easy setup for EV users who want quick access to EV charging.
Easy setup, no grid connection, but slow charging rates
The main challenge with distributed solar generation for EV charging is the low power output of photovoltaic panels. Most produce around 250 Watts per square meter, which is relatively low. In fact, to charge at 22kW (generally considered Level 2 fast charging), a solar canopy would need to be at least 10 x 10 meters, a considerable footprint, especially in an urban environment. The other challenge is storing energy, as charging will not always be required constantly, so an on-site battery is required to store the generated electricity. Without an integrated on-site battery, charging is impossible when there is no sunlight, such as inclement weather or overnight. On-site battery storage can combat this intermittency.
Larger solar farms with integrated energy storage can become islanded microgrids, and with enough on-site storage and photovoltaic production, potential grid-independent fast charging is possible. This is the approach proposed for the South African etruck charging network. It is important to note that purely solar solutions are likely to be geographically restricted to areas with high photovoltaic potential. Thus, it is no surprise that the leading regions are Western regions of the US and places like South Africa. Beam Global, a supplier of EV canopy chargers, recently announced its first sales in the European market to the United Kingdom Ministry of Defense. However, the chargers will not be deployed in the mainland of the UK; they will be deployed on a military base in Cyprus, one of the sunniest regions on the continent.
Despite technical challenges, the aging and fossil fuel-heavy nature of grids combined with high EV uptake call for new charging solutions, and IDTechEx predicts that solar charging systems will make up a sizeable portion of the overall US$16 billion off-grid charging infrastructure hardware market by 2034. IDTechEx research also indicates several other technologies likely to be adopted for off-grid EV charging. Hydrogen fuel cell charging is likely to emerge as a key solution for use cases requiring much greater power per area, with a particular expected focus on electrified construction sites. More niche technologies include AWE (airborne wind energy), which harnesses high altitude winds for distributed power generation. For an in-depth look at solar EV charging, as well as alternative technology options such as AWE and hydrogen see IDTechEx’s latest research on the topic, “Off-Grid Charging For Electric Vehicles 2024-2034: Technologies, Benchmarking, Players and Forecasts”.
