Quantum computing, with its potential to revolutionize various industries, is approaching the era of quantum advantage. As researchers and companies envision a future filled with powerful quantum computers, the focus has shifted towards scalability and practicality. Finland-based quantum startup SemiQon believes that the next phase of quantum computing will be achieved through the development of semiconductor-based quantum hardware.
The Challenge of Scalability
While first-generation quantum computers have made impressive strides in solving complex problems related to pharmaceuticals, logistics, and materials design, they have yet to achieve the desired “quantum advantage” over classical computers. To truly demonstrate the capabilities of quantum computers, they need to surpass the performance of their classical counterparts. This requires tackling the challenge of scalability.
Integration with High-Performance Computing (HPC)
The next milestone in quantum computing is the integration of quantum computers with high-performance computing (HPC) environments, commonly known as supercomputers. This integration will showcase the benefits of combining quantum and classical computing power. Subsequently, further advancements in quantum computing capacity will pave the way for scalable quantum computers.
Reevaluating the Importance of Hardware
While software has traditionally been considered more valuable than hardware in the world of classical computing, the strategic value of hardware should not be underestimated. The recent chip shortage has highlighted the risks of overreliance on external chip suppliers. In response, policymakers in Europe and the US are promoting local semiconductor industries to maintain control over the chip supply chain.
The Role of Semiconductors in Quantum Computing
SemiQon believes that semiconductor technology holds the key to overcoming the current limitations of quantum hardware. By utilizing silicon-based quantum chips, they aim to fabricate quantum processors in a cost-effective and scalable manner. This approach also allows quantum computers to operate at warmer temperatures, reducing energy consumption.
