Ultimately, my mission at ASU is to develop a state-of-the-art quantum networking research program supporting end-to-end entanglement throughout the Phoenix area and beyond
The catalyzing field for distributed quantum information processing
As a subfield of quantum information science and technology or QIST, quantum networking focuses on transmitting quantum information and establishing entanglement between quantum nodes, capabilities critical for applications such as secure communications, distributed quantum sensing, and connected quantum computers. Just like social networking pioneered new ways for people to communicate, we may one day look back on quantum networking as the catalyzing field for ushering in a new era of communications based on quantum properties that are difficult for humans to fathom.
No one researcher or institution can do everything alone. An attitude of openness and working together will be the key to pushing this field forward.
Areas of research
A state-of-the-art quantum networking research program supporting end-to-end entanglement throughout the world.
Quantum networking
Quantum networks will fundamentally change how we communicate, enabling unprecedented functionalities in quantum computing, security, and sensing. We are developing practical approaches for quantum networks that integrate seamlessly within the existing fiber-optic infrastructure, leveraging advanced capabilities from classical lightwave communications.
Frequency-bin quantum information processing
Frequency-bin encoding—in which quantum information is carried by single photons spanning multiple discrete frequency modes—offers exciting opportunities in quantum communications and networking, due to its natural stability in optical fiber and compatibility with wavelength-multiplexed communications. We are exploring and refining the quantum frequency processor (QFP) for universal quantum information processing in this emerging degree of freedom. Based on commercial telecom components, the QFP opens an exciting door for scalable quantum networking in highly multiplexed fiber-optic environments.
Bayesian quantum parameter estimation
Bayes’ theorem provides a principled logical framework for estimating unknown parameters from any collection of measurements, yet the application of Bayesian inference is frequently thwarted by the computational challenges associated with sampling from high-dimensional distributions. We are developing efficient Monte Carlo approaches for applications in quantum state and channel tomography, leveraging advances from statistics and applying them to problems in modern quantum information science.
Working at the speed of light
Our research supports entangled quantum systems that share properties with other quantum systems far away from them. Harnessing end-to-end entanglement, quantum networking would allow a computer to be entangled with a device potentially on the other side of the world — interacting with them at unprecedented sensitivity and security, on demand.
Entanglement refers to a group of particles that are so intertwined that actions performed on one can impact the others, even when they are very far apart from each other — like rolling two dice and getting matched numbers every time.
At the Quantum Networking Lab, our work in entanglement could eventually lead to the creation of a powerful quantum internet and safer communication between systems, among other groundbreaking advancements.
Bolstered by strong partnerships in academia and with industry including IBM, Dell Technologies and Quantinuum, the Quantum Collaborative also aims to usher in the next generation of quantum innovators.
