UCF Quantum Computing news
A recent colloquium at the University of Central Florida featured assistant professor Dr. Han Zhao’s innovative quantum network research. Zhao will leave the California Institute of Technology to build a quantum computing lab and study various approaches.
To get beyond the budgetary and technical constraints of growing a single machine, his approach entails connecting various hardware and qubit kinds across many refrigeration units. He wants to use fiber-optic technology to create a working campus network in partnership with other academic members. By assisting in the construction of the laboratory infrastructure from the bottom up to accommodate these intricate investigations, graduate assistant Shantanu Chaudhary is assisting with this shift. Ultimately, the initiative aims to provide a more workable foundation for future quantum communications while avoiding conventional computer constraints.

The Vision: A Heterogeneous Network
Dr. Zhao, a new member of the Department of Physics who joined UCF from Caltech last year, is spearheading a “new approach” to quantum computing. Rather than using traditional methods, his lab is working on a heterogeneous quantum network.
The goal of this paradigm is to combine different kinds of hardware, such as:
- Superconducting qubits
- Photonic qubits
- Silicon defect centers
Zhao aims to answer new issues that the industry’s established methods are now unable to handle by fusing these various technologies.
Resolving the “Scaling Bottleneck”
The scalability problem is at the core of Zhao’s study. Quantum computers employ qubits, which are capable of simultaneously existing in the states of one and zero, in contrast to normal computers, which use bits, or ones and zeros. Higher data storage and far more complicated calculations are made possible by this.
However, these systems are commonly hard to scale. The issue is that quantum computing has a high rate of mistakes when it is used, and Zhao clarified that this is due to our restricted capacity to increase the quantum computer’s size.
Right now, temperature is the physical constraint. Quantum computers require dilution freezers that are chilled to 10 millikelvin, or around minus 459.49 degrees Fahrenheit, or the temperature of space, to function.
Decentralization is the method Zhao’s study suggests to get over this bottleneck. Zhao proposes distributing the qubits across several units, such as 100 qubits in each of ten refrigerators, rather than attempting to fit a large number of qubits (like a thousand) in a single, gigantic, costly refrigerator.

From Concept to Realistic Laboratory Work
Graduate student Shantanu Chaudhary, a Georgia Institute of Technology alumnus presently earning his master’s and PhD degrees at UCF, is helping Zhao with this activity. A month following Zhao’s arrival on campus, Chaudhary joined the project and assisted in the lab’s construction. Chaudhary referred to the process as a “crash course” in establishing a scientific institution, saying, “We started with literally nothing in the lab.” In his work, he does:
- Accurately adjusting equipment for quantum research.
- Taking care of logistics, including ordering parts and haggling with businesses over rates.
- Working together to apply quantum theory with other researchers.
Chaudhary finds fulfillment in the project as he sees abstract concepts becoming “something real.”

UCF’s Communications Future
The eventual objective of this project is to connect various kinds of qubits at UCF using fiber-optic cables to establish a functioning quantum network. This is in line with the university’s increasing focus on future telecommunications technology and secure communications.
Although Zhao just completed buying and starting to build the required equipment, the effort is still in its early phases and marks a major advancement for the university’s reputation in quantum photonics.
