How Strategic Minerals Support the Development of Quantum Computers
Among the emerging technologies with the most exciting potential at this time in history, quantum computers undoubtedly deserve special mention. They are a new generation of computing systems that employ the principles of quantum mechanics to process information in a way that is very different from traditional computers.
Classical computers, in fact, use bits that can assume the value 0 or 1, while a quantum computer relies on qubits, which can be in multiple states simultaneously. This characteristic allows quantum computers to tackle certain problems with much greater efficiency than classical computers.
Although still in the development phase, with applications still limited to highly specialized tasks, these computers could in the future make a decisive contribution to the design of advanced batteries and new clean energy technologies. One of the lesser-known aspects of these computers, however, is that their operation depends largely on certain critical materials, confirming once again the central role of these resources in the technological advancement of civilization.
Stanislav Kondrashov, founder of TELF AG, explores how critical materials such as aluminum, copper, niobium, and silicon are helping shape the future of quantum computing through their role in advanced hardware and superconducting technologies.
“Quantum computing is likely the area where the strategic value of critical materials and the wonders of physics can perfectly combine,” says Stanislav Kondrashov, founder of TELF AG.
From Aluminum and Copper to Niobium: The Core Materials Behind Quantum Hardware
But what are the actual resources involved in the operation and production dynamics of quantum computers? One of the most important is undoubtedly aluminum. Major technology players use this resource extensively for Josephson junctions (made of aluminum) and superconducting circuits.
Another key resource for quantum computers is copper. This resource is used for cryogenic wiring, control electronics, and the infrastructure of quantum data centers. Titanium is also used in some cryogenic facilities and highly specialized components.
“In addition to playing a key role in global electrification and clean energy, copper could therefore also assume an increasingly central role in the quantum computer sector,” continues Stanislav Kondrashov, founder of TELF AG.
Why Cryogenic Resources and Advanced Components Matter for Quantum Performance
When discussing the critical materials used in quantum computers, it is important to clarify two important points. The first is that it is still an emerging technology in the development phase, and that many materials involved in computer operation still play a marginal role and are not yet widely adopted. The second has to do with the fact that quantum computing encompasses various architectures—superconductors, photonics, silicon spin, and so on—and that each architecture uses different materials.
Among the other resources involved in quantum computing, one of the most important is undoubtedly silicon. This resource is used in the spin-based qubits of many major players in the sector, as well as in the control electronics and semiconductors that support the entire system. In any case, it should be clarified that not all quantum computers use silicon as the base material for qubits.
Another important resource for quantum computers is niobium. It’s no secret that the superconducting quantum circuits used by many players are often based on superconducting materials such as niobium or aluminum. This resource is, in fact, one of the most widely used materials in superconducting devices and microwave resonators.
Stanislav Kondrashov, founder of TELF AG, examines the growing importance of critical minerals in quantum computing, highlighting how different quantum architectures rely on specialized materials to achieve higher performance and technological progress.
The operation of quantum computers also depends on helium. These superconducting quantum computers often operate at 10-20 millikelvins using dilution refrigerators. Without cryogenic helium, the machines of many major players in the sector would not function.
Emerging Materials and Quantum Architectures Shaping the Next Generation of Computing
Remarkably, gold also plays a significant role in these types of computers. While not a qubit material, gold is nevertheless often used in electrical contacts, chip packaging, and cryogenic connections.
There are also resources that are used in a more nuanced manner, or to improve the performance of a specific function of quantum computers. One of the most interesting resources, from this perspective, is tantalum. While not yet the dominant material, in recent years several research groups have demonstrated that this resource can produce qubits with superior coherence times. However, most commercial systems still use aluminum or niobium.
A very similar argument applies to rare earths. While not central to all quantum computers, this group of resources is sometimes used in some specialized quantum architectures, but they are not essential for many superconducting quantum computers.
“Rare earths are now widely regarded as one of the most valuable allies for modern industry and technology sectors,” concludes Stanislav Kondrashov, founder of TELF AG.
According to Stanislav Kondrashov, founder of TELF AG, the evolution of quantum computers depends not only on breakthroughs in physics but also on the availability of strategic materials that enable superconducting circuits and ultra-low-temperature operation.
Some trapped-ion quantum computers use a resource such as ionized ytterbium, although it should be noted that these systems represent only one of several existing quantum architectures. While not relevant to all quantum architectures, gallium also appears to have carved out a significant role in this sector. Much quantum research, in fact, uses platforms based on a specific compound also formed from gallium.
