Cryogenic Semiconductor Designs for Quantum Computing

Over the last few years, there has been an increase in news about quantum computing. Much of this news coverage has been around computing supremacy, potential threats to information security and quantum cryptography. While the field of quantum computing is still in its early stages, there are several companies who have already developed quantum computers. And these companies often leverage proprietary semiconductor fabrication technologies to build chips for their quantum computers. As such, much information about their semiconductor chips is not publicly disclosed. On top of that, media coverage tends to emphasize practical applications of quantum computing rather than the underlying semiconductor technologies. Achievements like quantum supremacy demonstrations, advancements in quantum algorithms, and industry collaborations often take precedence in news coverage over semiconductor technologies. Nonetheless, quantum computing is not possible without semiconductors that are capable of operating at temperatures near absolute zero. These cryogenic semiconductors are fundamental components of quantum computing systems and a recent announcement by Siemens EDA provides some insights into what is involved in designing these cryogenic chips.

Siemens EDA is collaborating with sureCore and Semiwise to develop quantum computing ready cryogenic CMOS chips. The technologies and solutions developed through this collaboration have the potential to redefine the boundaries of high-performance computing.

Quantum Computing and Cryogenic Chips

Quantum computing relies on quantum bits or qubits, which exhibit quantum mechanical properties such as superposition and entanglement. To maintain the delicate quantum states necessary for computation, qubits must be shielded from external disturbances, such as thermal noise and electromagnetic interference. Operating at cryogenic temperatures helps mitigate these challenges and stabilizes the quantum states, reducing errors and enhancing the reliability of quantum computations. Cryogenic chips are essential for constructing control electronics, enabling the precise manipulation and measurement of qubits.
