3 articles · Updated · HPCwire · Jul 2
Summary
Han Zhao at the University of Central Florida is developing a quantum entanglement method that aims to make operations more resistant to noise and hardware errors, an alternative to resource-heavy quantum error correction.
The approach pairs superconducting quantum circuits with nanomechanical resonators, using topological “braiding” so quantum states follow a stable interaction pattern rather than relying on perfectly precise control.
Near-absolute-zero experiments in a dilution refrigerator let Zhao’s lab study how microwave signals and microscopic vibrating structures exchange quantum information while minimizing thermal disruption.
The work is backed by the Oak Ridge Associated Universities Ralph E. Powe Junior Faculty Enhancement Award, with funding supporting graduate research, specialized superconducting hardware and use of UCF nanofabrication facilities.
If successful, the method could advance fault-tolerant quantum computing for applications such as quantum simulation, complex optimization, materials discovery and information security.
In July 2026, Assistant Professor Han Zhao at the University of Central Florida achieved a major breakthrough by introducing a new method for fault-tolerant quantum entanglement. His research focuses on making quantum operations more resistant to noise and errors, which is a key challenge in building practical quantum computers. Zhao’s approach combines superconducting quantum systems with nanomechanical devices, all operating at temperatures near absolute zero. By using tiny mechanical resonators that interact precisely with microwave signals, his work aims to stabilize quantum entanglement and pave the way for more reliable and scalable quantum technologies.
