Researchers are turning to quantum techniques to boost noise-resistant nanoscale wireless communication between chips – a breakthrough that could revolutionize future technology
As computing shifts from single-chip processors to multi-chip systems, traditional communications methods, such as Network-on-Chip (NoC) and Network-in-Package (NiP), are becoming less efficient. To address these limitations, scientists are exploring terahertz frequencies for high-speed data transmission despite the challenge of noise interference, which makes data decoding difficult.
A research team from universities in Australia and the US has been studying wireless communications at the chip level and looking for ways to reduce noise. By applying Floquet technique, a quantum technique that manipulates the behavior of electrons, they discovered that they could improve terahertz signal detection.
When implemented in a two-dimensional semiconductor quantum source (2DSQW), the approach successfully reduced noise and increased signal clarity. The team’s findings suggest that this method could pave the way for more effective and reliable wireless communications between chiplets, and provide a potential solution to the efficiency challenges faced by multi-chip systems.
Broad applications
The team also developed a dual signaling system that uses two receivers to monitor noise levels and adjust signals in real time, further reducing the error rate.

This innovation brings us closer to creating more efficient, scalable and adaptable computing systems for tomorrow’s technologies.”
Their findings were published in the IEEE Journal on Selected Areas in Communications.
As we previously reported, universities are also looking at ways to increase the potential of terahertz technology to unlock bandwidth for future telecommunications.
The University of Adelaide has developed a polarization multiplexer that doubles data transmission capacity at terahertz frequencies, while researchers at the University of Notre Dame demonstrated a silicon topological beamformer chip that can split a single terahertz signal into 54 smaller beams.
