Noise-Resilient Quantum Evolution in Open Systems through Error-Correcting Frameworks
Nirupam Basak, Goutam Paul, Pritam Chattopadhyay
We analyze quantum state preservation in open quantum systems using quantum error-correcting (QEC) codes explicitly embedded in microscopic system-bath models. Rather than assuming…
Faster Optimal Decoder for Graph Codes with a Single Logical Qubit
Nirupam Basak, Goutam Paul
In this work, we develop an efficient decoding method for graph codes, a class of stabilizer quantum error-correcting codes constructed from graph states. While optimal decoding is…
Hierarchical quantum decoders
Nirupam Basak, Ankith Mohan, Andrew Tanggara +3
Decoders are a critical component of fault-tolerant quantum computing. They must identify errors based on syndrome measurements to correct quantum states. While finding the optimal…
Evaluating Quantumness, Efficiency and Cost of Quantum Random Number Generators via Photon Statistics
Goutam Paul, Nirupam Basak, Soumya Das
This work presents two significant contributions from the perspectives of quantum random number generator (QRNG) manufacturers and users. For manufacturers, the conventional method…
Approximate Dynamical Quantum Error-Correcting Codes
Nirupam Basak, Andrew Tanggara, Ankith Mohan +2
Quantum error correction plays a critical role in enabling fault-tolerant quantum computing by protecting fragile quantum information from noise. While general-purpose quantum erro…
Resource Reduction in Multiparty Quantum Secret Sharing of both Classical and Quantum Information under Noisy Scenario
Nirupam Basak, Goutam Paul
Quantum secret sharing (QSS) enables secure distribution of information among multiple parties but remains vulnerable to noise. We analyze the effects of bit-flip, phase-flip, and…
