Towards the Characterization of Logical Errors in Distributed Lattice Surgery
Nitish Kumar Chandra, Reza Nejabati, Eneet Kaur
Distributed quantum computing offers a scalable alternative to monolithic quantum processors by networking smaller quantum modules through shared entangled pairs. A central challen…
Impact of Network Constraints on Fault-Tolerant Distributed Quantum Computing
Eneet Kaur, Shahrooz Pouryousef, Nitish Kumar Chandra +4
As we move towards scalable and modular quantum computing, quantum data centres become imperative. Existing analyses typically treat network constraints in isolation or through sim…
ATHENA: A Compiler For Optimized Scheduling In Distributed Quantum Computers
Won Joon Yun, Dhilan Nag, Sneha Ballabh +3
Distributed Quantum Computers (DQCs) enable large system sizes by connecting smaller chips via photonic interconnects. DQCs use teleportation to relocate qubits and execute CNOTs b…
Distributed Quantum Error Correction with Bivariate Bicycle Codes in a Modular Architecture
Nitish Kumar Chandra, Eneet Kaur, Reza Nejabati +1
Quantum low density parity check (qLDPC) codes, particularly bivariate bicycle (BB) codes, achieve competitive fault tolerance thresholds while offering substantially higher encodi…
Lower bounds on bipartite entanglement in noisy graph states
Aqil Sajjad, Eneet Kaur, Kenneth Goodenough +2
Graph states are a key resource for a number of applications in quantum information theory. Due to the inherent noise in noisy intermediate-scale quantum (NISQ) era devices, it is…
RADAR-Q: Resource-Aware Distributed Asynchronous Routing for Entanglement Distribution in Multi-Tenant Quantum Networks
Chenliang Tian, Zebo Yang, Raj Jain +6
Scalable quantum networks must support concurrent entanglement requests, yet existing routing protocols fail when users compete for shared repeater resources, wasting fragile quant…
