Quantum computing could transform how we solve complex energy and climate problems. The simplest way to understand quantum computing is to contrast it with the classical computer systems. Traditional computers reduce all information to binary states. Every calculation ultimately reduces to zeros and ones, processed in sequence. This architecture has proven extraordinarily powerful, but it cannot handle the full complexity of the physical world.
Quantum computing begins from a different premise. At the most fundamental level, the universe is governed by quantum mechanics. Quantum systems can occupy multiple states at once, only collapsing into a definite outcome when they are measured. This is a bit like Schrödinger’s cat, where a system can exist in multiple states at once until it is measured. If this still feels abstract, don’t worry. As one professor once said, “By the end of the course, you won’t understand quantum mechanics, but you will understand why I don’t either.”
Quantum computing attempts to build a computational framework that reflects our underlying quantum reality. Instead of binary bits, quantum systems use qubits, which can exist in multiple states at once. That capability allows a quantum computer to evaluate a range of possibilities simultaneously rather than sequentially. The practical implication is not just speed, but the ability to handle complexity that would overwhelm classical systems.
This distinction becomes particularly important in fields like chemistry and material science, where interactions occur at the quantum level. When classical computers attempt to simulate these interactions, they rely on approximations that grow less accurate as systems become more complex. A quantum computer, operating under the same principles as the system it is modeling, has the potential to generate far more precise results.
It is also worth clarifying what quantum computing is not. It is not simply a more powerful version of artificial intelligence. AI systems are, in essence, prediction machines, designed to detect patterns in data and generate outputs based on those patterns. They are exceptionally useful for tasks such as forecasting and optimization. Quantum computing, by contrast, is aimed at problems that are currently beyond the reach of classical computers, particularly those tied to the fundamental behavior of matter.

Quantum computing is particularly well suited to two kinds of problems at the heart of the energy and climate challenge.
The first is simulation. Climate systems are complex networks of feedback loops and dependencies. A quantum algorithm can model a system using the same physical laws it follows, promising greater accuracy than classical computers can achieve.
The second is material discovery. Many energy technologies hinge on designing materials with specific properties. Right now, finding these materials still relies too much on trial and error, supported by calculations that do not fully capture molecular behavior. Quantum computing can simulate those interactions more faithfully, cutting down uncertainty and speeding the path from lab to market.
As quantum algorithms move into practice, their impact on energy and climate will likely concentrate in a few key areas.
Carbon capture refers to technologies that filter out carbon at the source of pollution, often at smokestacks or within industrial processes, before it enters the atmosphere. Yet existing carbon capture solutions remain expensive, energy intensive, and often inefficient at scale.
A significant part of the challenge lies in the materials used to capture carbon dioxide, especially filtration membranes. Quantum algorithms can simulate how different molecular structures interact with carbon dioxide. If more efficient materials can be identified, the cost structure of carbon capture could shift significantly, making it a more viable solution at scale.
Biological systems, such as plants, convert sunlight into energy with remarkable efficiency through processes that are not yet fully replicated in artificial systems. Understanding these processes requires analyzing interactions at the quantum level, where energy transfer occurs in ways that are difficult to capture with classical models. With the help of quantum computing, the goal is to design materials that mimic the efficiency of natural systems, potentially leading to a new generation of solar technologies.
Energy storage is another area where material limitations are a central concern. Batteries must balance competing demands, including energy density, charging speed, durability, safety, and cost. Improvements in one area often come at the expense of another.
Understanding and optimizing chemical reactions within batteries requires detailed knowledge of how molecules behave under different conditions. Quantum computing provides a way to simulate these interactions with greater accuracy, helping the development of new battery chemistries.
The concept of fusion is straightforward: harness the same processes that power the sun to generate clean, virtually limitless energy. The challenge lies in creating conditions where those processes can be controlled on Earth.
One of the primary obstacles is the development of materials that can withstand the extreme temperatures and pressures involved. Quantum computing offers a pathway to simulate how atoms behave under extreme conditions, helping researchers identify new materials that could meet these demands.
Quantum algorithm development is thriving, driven by applications in trading, finance, cryptography, and cybersecurity. Given its early stage, it may be wise to redirect attention toward societal problems like energy and climate. As with AI, the risk is that technical progress can move faster than thoughtful application design and safeguards, so shaping quantum algorithms now can help ensure that the first major uses are not limited to narrow commercial interests.
The 7 finalists in the XPRIZE Quantum Applications competition
XPRIZE
The XPRIZE competition framework offers a structured way to ensure that emerging technologies are used for the greater good. “When you come to these very powerful technologies that can shape our future, it is important how we direct the attention of the creators”, said Anousheh Ansari, CEO of XPRIZE.
In the case of quantum computing, the organization launched a $5 million competition in 2024 focused specifically on quantum algorithms. The competition is global, attracting 133 teams from around the world. Participants range from early-stage researchers to more developed startups, reflecting different stages of technological maturity. Importantly, XPRIZE does not take intellectual property from participants. Teams retain full ownership of their innovations. The funding provided is non-dilutive, functioning more like a grant than venture capital.
Seven finalist teams were selected in December 2025, with the winner to be announced in 2027. Beyond the prize itself, XPRIZE acts as a connector within the broader ecosystem. It links teams with mentors, investors, and research institutions. Even those that do not win continue to receive support through an alumni network, which helps advance their work beyond the competition. In later stages, XPRIZE also plays an accelerator role, either directly or through partnerships, helping teams transition from concept to investment-ready ventures. “If we solve the energy problem, we can basically solve anything,” concluded Anousheh Ansari.
If quantum computing reaches its expected potential, the implications for energy systems are difficult to overstate. One immediate effect would be a significant acceleration in material discovery. Processes that currently take years or decades could be compressed, enabling faster development of technologies across the energy spectrum. More accurate climate models could inform policy, while better system-level analysis could optimize energy production and distribution. Perhaps most importantly, quantum computing could expand the range of solutions that are feasible. Technologies that are currently limited by material constraints or computational barriers could find their way to the consumers.
