Breakthrough in Quantum Computing: Atomically Thin Transistors Enable Room Temperature Operation

Strategic Insights

— 1 min read

Researchers at Northeastern University, led by Assistant Professor Yoseob Yoon, have made a significant discovery in the field of quantum computing. By combining the study of laser-based thermal transport with the properties of atomically thin materials, the team has created a new regime of operation for transistors that could enable quantum computing at room temperature. This breakthrough has the potential to revolutionize the field of quantum computing, which currently requires machines to be kept at extremely low temperatures to function.

Key Takeaways:

  • Yoseob Yoon, Assistant Professor of Mechanical and Industrial Engineering at Northeastern University, has discovered a way to create atomically thin transistors that could enable quantum computing at room temperature.
  • The new transistors are created by aligning atomically thin structures with the study of laser-based thermal transport, allowing control at terahertz frequencies.
  • The terahertz frequency range is an increase by a factor of a thousand from the current limit of gigahertz frequencies, enabling quantum computers to run at room temperatures.
  • The discovery combines the fields of thermal transport using thin metallic films and 2D-material field studies, allowing for novel van der Waals heterostructures creation.
  • The breakthrough is a significant step toward enabling room temperature quantum computing, but it is not yet the ultimate solution, as quantum signals will decay faster at higher temperatures.
  • The next step in the research involves pushing the limit of the amplitude of the transistors.

Statistics:

  • The temperature range for current quantum computers is around a few degrees above absolute zero (-460°F).
  • The new transistors can operate at terahertz frequencies, which is an increase by a factor of a thousand from the current limit of gigahertz frequencies.
  • The research involves the study of laser-based thermal transport with atomically thin materials, which has combined the fields of thermal transport using thin metallic films and 2D-material field studies.
  • The team has identified novel van der Waals heterostructures that allow control at terahertz frequencies.
