An on-demand resource allocation algorithm for a quantum network hub and its performance analysis (2025)
Presentation / Conference Contribution
Gauthier, S., Vasantam, T., & Vardoyan, G. (2024, September). An on-demand resource allocation algorithm for a quantum network hub and its performance analysis. Presented at QCE24: IEEE International Conference on Quantum Computing and Engineering, Montréal, Québec, Canada

To support the execution of multiple simultaneously-running quantum network applications, a quantum network must efficiently allocate shared resources. We study traffic models for a type of quantum network hub called an Entanglement Generation Switch...

Calculating the Capacity Region of a Quantum Switch (2025)
Presentation / Conference Contribution
Tillman, I., Vasantam, T., Towsley, D., & Seshadreesan, K. P. (2024, September). Calculating the Capacity Region of a Quantum Switch. Presented at QCE2024: IEEE International Conference on Quantum Computing and Engineering, Montréal, Québec, Canada

Quantum repeaters are necessary to fully realize the capabilities of the emerging quantum internet, especially applications involving distributing entanglement across long distances. A more general notion of this can be called a quantum switch, which... Read More about Calculating the Capacity Region of a Quantum Switch.

Optimal Scheduling in a Quantum Switch (2024)
Journal Article
Bhambay, S., Vasantam, T., & Walton, N. (in press). Optimal Scheduling in a Quantum Switch. ACM SIGMETRICS Performance Evaluation Review,

With a growing number of quantum networks in operation, there is a pressing need for performance analysis of quantum switching technologies. A quantum switch establishes, distributes, and maintains entanglements across a network. In contrast to a cla... Read More about Optimal Scheduling in a Quantum Switch.

The impact of load comparison errors on the power-of-d load balancing (2024)
Journal Article
Bhambay, S., Mukhopadhyay, A., & Vasantam, T. (2024). The impact of load comparison errors on the power-of-d load balancing. Performance Evaluation, 164, Article 102408. https://doi.org/10.1016/j.peva.2024.102408

We consider a system with 𝑛 unit-rate servers where jobs arrive according a Poisson process with rate 𝑛𝜆 (𝜆 < 1). In the standard Power-of-𝑑 or Pod scheme with 𝑑 ≥ 2, for each incoming job, a dispatcher samples 𝑑 servers uniformly at random and sends...

The Power of Two Choices with Load Comparison Errors (2023)
Presentation / Conference Contribution
Bhambay, S., Mukhopadhyay, A., & Vasantam, T. (2023, October). The Power of Two Choices with Load Comparison Errors. Presented at MobiHoc '23: The Twenty-fourth International Symposium on Theory, Algorithmic Foundations, and Protocol Design for Mobile Networks and Mobile Computing, Washington, DC

We consider a system with n unit-rate servers where jobs arrive according a Poisson process with rate nλ (λ < 1). In the standard Power-of-two or Po2 scheme, for each incoming job, a job dispatcher samples two servers uniformly at random and sends th...

On the Capacity Region of a Quantum Switch with Entanglement Purification (2023)
Presentation / Conference Contribution
Panigrahy, N. K., Vasantam, T., Towsley, D., & Tassiulas, L. (2023, May). On the Capacity Region of a Quantum Switch with Entanglement Purification. Paper presented at INFOCOM 2023: IEEE International Conference on Computer Communications, New York

Quantum switches are envisioned to be an integral component of future entanglement distribution networks. They can provide high quality entanglement distribution service to end-users by performing quantum operations such as entanglement swapping and...

A Continuous Variable Quantum Switch (2022)
Presentation / Conference Contribution
Tillman, I., Vasantam, T., & Seshadreesan, K. P. (2022, November). A Continuous Variable Quantum Switch. Presented at IEEE Quantum Week 2022 - International Conference on Quantum Computing and Engineering (QCE), Broomfield, Colorado

The continuous quadratures of a single mode of the light field present a promising avenue to encode quantum information. By virtue of the infinite dimensionality of the associated Hilbert space, quantum states of these continuous variables (CV) can e... Read More about A Continuous Variable Quantum Switch.

On the Analysis and Evaluation of Proximity Based Load Balancing Policies (2022)
Journal Article
Panigrahy, N. K., Vasantam, T., Basu, P., Towsley, D., Swami, A., & Leung, K. K. (2022). On the Analysis and Evaluation of Proximity Based Load Balancing Policies. ACM Transactions on Modeling and Performance Evaluation of Computing Systems, 7(2-4), Article 6. https://doi.org/10.1145/3549933

Distributed load balancing is the act of allocating jobs among a set of servers as evenly as possible. The static interpretation of distributed load balancing leads to formulating the load balancing problem as a classical balls and bins problem with...

A throughput optimal scheduling policy for a quantum switch (2022)
Presentation / Conference Contribution
Vasantam, T., & Towsley, D. (2022, December). A throughput optimal scheduling policy for a quantum switch. Presented at Quantum Computing, Communication, and Simulation II, San Fransisco

We study a quantum switch that creates shared end-to-end entangled quantum states to multiple sets of users that are connected to it. Each user is connected to the switch via an optical link across which bipartite Bell-state entangled states are gene... Read More about A throughput optimal scheduling policy for a quantum switch.
