The Future of Quantum Computing Seen from the News on Next-Generation Semiconductor-Based Quantum Computers by Major Companies in Japan and the U.S.
The Arrival of the Next-Generation Semiconductor Quantum Computing Era – The Ultimate Race for the Leading Technology!
The time has finally come.
For decades, quantum computers have been discussed as "the technology of the future," with numerous research institutions and companies exploring various approaches. However, the most promising technology has now entered a full-scale development phase: semiconductor-based quantum computing.
This field may become the final battleground for quantum computer development. Unlike other quantum computing, semiconductor-based quantum computers hold the potential to achieve large-scale integration, miniaturization, and improved stability, paving the way for the ultimate quantum computer. A prime example of this trend is the recent news that the National Institute of Advanced Industrial Science and Technology (AIST) and Intel have officially begun developing next-generation semiconductor quantum computers.
What Is a Semiconductor Quantum Computer? Why Is It Considered the Leading Technology?
A semiconductor quantum computer constructs qubits using advanced transistor technology. While most existing quantum computers require operation at extremely low temperatures, semiconductor-based approaches have the advantage of leveraging existing semiconductor industry technologies. In particular, silicon quantum dots and spin qubits are considered highly promising.
If this technology is fully realized, it could bring about revolutionary changes:
- Miniaturization and Large-Scale Integration: While superconducting quantum computers struggle to scale beyond a few thousand qubits, semiconductor quantum computers could, in theory, integrate millions of qubits on a single chip, similar to current silicon-based semiconductor technology.
- Compatibility with Existing Semiconductor Manufacturing: Since this approach extends existing silicon technology, it could utilize current semiconductor fabrication facilities, making mass production theoretically possible.
- Improved Stability: Semiconductor qubits have the potential for longer coherence times, improving reliability.
If these advancements come to fruition, quantum computers will finally enter the practical stage.
However, Development Remains Extremely Challenging
Despite its potential, semiconductor quantum computer development faces immense technical challenges. Controlling quantum states with high precision and integrating error correction mechanisms require nano-scale precision engineering and cutting-edge fabrication techniques.
One of the most difficult challenges is controlling noise and improving readout accuracy as qubits are scaled up. Furthermore, this is not just an advancement of semiconductor technology—it represents an entirely new domain where quantum physics and nanotechnology converge. Success in this field demands collaboration among the world's top researchers and engineers.
The efforts of AIST and Intel reflect preparations for the ultimate battle in quantum computing. Countries like China and the U.S. are also deeply invested in this technology, intensifying the global development race.
