A Graph-Based Forensic Framework for Inferring Hardware Noise of Cloud Quantum Backend
Subrata Das, Archisman Ghosh, Swaroop Ghosh
Cloud quantum platforms give users access to many backends with different qubit technologies, coupling layouts, and noise levels. The execution of a circuit, however, depends on in…
Optimization of Quantum Error Correcting Code under Temporal Variation of Qubit Quality
Subrata Das, Swaroop Ghosh
Error rates in current noisy quantum hardware are not static; they vary over time and across qubits. This temporal and spatial variation challenges the effectiveness of fixed-dista…
Impact of Error Rate Misreporting on Resource Allocation in Multi-tenant Quantum Computing and Defense
Subrata Das, Swaroop Ghosh
Cloud-based quantum service providers allow multiple users to run programs on shared hardware concurrently to maximize resource utilization and minimize operational costs. This mul…
Investigating impact of bit-flip errors in control electronics on quantum computation
Subrata Das, Avimita Chatterjee, Swaroop Ghosh
In this paper, we investigate the impact of bit flip errors in FPGA memories in control electronics on quantum computing systems. FPGA memories are integral in storing the amplitud…
Lattice Surgery for Dummies
Avimita Chatterjee, Subrata Das, Swaroop Ghosh
Quantum error correction (QEC) plays a crucial role in correcting noise and paving the way for fault-tolerant quantum computing. This field has seen significant advancements, with…
