Boundary-Aware Stabilizer Scheduling for Distributed Quantum Error Correction
Sanidhya Gupta, Sanidhay Bhambay, Narges Alavisamani +2
Future quantum architectures are expected to be modular, with quantum processors connecting multiple quantum processing units (QPUs) via photonic interconnects. In topological quan…
Adaptive Aborting Schemes for Quantum Error Correction Decoding
Sanidhay Bhambay, Prakash Murali, Neil Walton +1
Quantum error correction (QEC) is essential for realizing fault-tolerant quantum computation. Current QEC controllers execute all scheduled syndrome (parity-bit) measurement rounds…
Markov Decision Processing Networks
Sanidhay Bhambay, Thirupathaiah Vasantam, Neil Walton
We introduce Markov Decision Processing Networks (MDPNs) as a multiclass queueing network model where service is a controlled, finite-state Markov process. The model exhibits a dec…
The Proportional Fair Scheduler in Wavelength-Multiplexed Quantum Networks
Sanidhay Bhambay, Siddarth Koduru Joshi, Thirupathaiah Vasantam +1
We address the problem of optimal pumping strategies in quantum networks. These networks enable secure communication by distributing entangled photon pairs to user (or node) pairs.…
Service-the-Longest-Queue Among d Choices Policy for Quantum Entanglement Switching
Guo Xian Yau, Thirupathaiah Vasantam, Gayane Vardoyan
An Entanglement Generation Switch (EGS) is a quantum network hub that provides entangled states to a set of connected nodes by enabling them to share a limited number of hub resour…
Optimal Scheduling in a Quantum Switch
Sanidhay Bhambay, Thirupathaiah Vasantam, Neil Walton
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, distribut…
An on-demand resource allocation algorithm for a quantum network hub and its performance analysis
Scarlett Gauthier, Thirupathaiah Vasantam, Gayane Vardoyan
To effectively support the execution of quantum network applications for multiple sets of user-controlled quantum nodes, a quantum network must efficiently allocate shared resource…
Calculating the Capacity Region of a Quantum Switch
Ian Tillman, Thirupathaiah Vasantam, Don Towsley +1
Quantum repeaters are necessary to fully realize the capabilities of the emerging quantum internet, especially applications involving distributing entanglement across long distance…
The Power of Two Choices with Load Comparison Errors
Sanidhay Bhambay, Arpan Mukhopadhyay, Thirupathaiah Vasantam
In this paper, we analyze the effects of erroneous load comparisons on the performance of the Po2 scheme. Specifically, we consider load-dependent and load-independent errors. In t…

Quantum switches are envisioned to be an integral component of future entanglement distribution networks. They can provide high quality entanglement distribution service to end-use…
A Continuous Variable Quantum Switch
Ian Tillman, Thirupathaiah Vasantam, Kaushik P. Seshadreesan
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…
Quickest Change Detection in the Presence of Transient Adversarial Attacks
Thirupathaiah Vasantam, Don Towsley, Venugopal V. Veeravalli
We study a monitoring system in which the distributions of sensors' observations change from a nominal distribution to an abnormal distribution in response to an adversary's presen…
A Throughput Optimal Scheduling Policy for a Quantum Switch
Thirupathaiah Vasantam, Don Towsley
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 op…
Stability Analysis of a Quantum Network with Max-Weight Scheduling
Thirupathaiah Vasantam, Don Towsley
We study a quantum network that distributes entangled quantum states to multiple sets of users that are connected to the network. Each user is connected to a switch of the network…
Sensitivity of Mean-Field Fluctuations in Erlang loss models with randomized routing
