On April 14, 2026, the Electrical Engineering Department at the College of Engineering and Physics hosted a seminar titled “Quantum Electronics at Room Temperature,” delivered by Dr. Faris Abualnaja, Assistant Professor in Electrical Engineering at King Fahd University of Petroleum and Minerals (KFUPM). The seminar was held in Building 59.

During the seminar, Dr. Abualnaja discussed the emergence of quantum technologies as a promising pathway beyond the limitations of Moore’s law, where quantum effects dominate at the nanoscale. He introduced recent advancements in room-temperature quantum electronic devices, particularly focusing on single-electron and double quantum dot transistors based on dopant atoms in silicon dioxide (SiO₂).

Dr. Abualnaja explained key observed phenomena such as Coulomb oscillations, Coulomb diamonds, and charge stability diagrams at room temperature (290 K). He further described how these behaviors can be modeled using anharmonic Morse potentials, and demonstrated how coupled quantum dots can emulate a quantum Szilard engine, linking quantum transport with information entropy.

In addition, the seminar highlighted the broader implications of these findings for the development of scalable quantum electronic devices. Dr. Abualnaja emphasized the potential of such technologies to enable practical quantum systems operating at room temperature, paving the way for advancements in quantum sensing, computing, and nanoelectronic applications.

The following are the highlights of the event:
