Exactly solvable model of a passive Brownian heat engine and its comparison with active engines
Rita Majumdar, Arnab Saha, Rahul Marathe
We perform an extensive analysis of passive as well as active micro-heat engines with different single-particle stochastic models. Using stochastic thermodynamics we calculate ther…
Surface Code Design for Asymmetric Error Channels
Utkarsh Azad, Aleksandra Lipińska, Shilpa Mahato +3
Surface codes are quantum error correcting codes normally defined on 2D arrays of qubits. In this paper, we introduce a surface code design based on the fact that the severity of b…
Efficient Decoding of Surface Code Syndromes for Error Correction in Quantum Computing
Debasmita Bhoumik, Pinaki Sen, Ritajit Majumdar +3
Errors in surface code have typically been decoded by Minimum Weight Perfect Matching (MWPM) based method. Recently, neural-network-based Machine Learning (ML) techniques have been…
Depth Optimized Ansatz Circuit in QAOA for Max-Cut
Ritajit Majumdar, Debasmita Bhoumik, Dhiraj Madan +3
While a Quantum Approximate Optimization Algorithm (QAOA) is intended to provide a quantum advantage in finding approximate solutions to combinatorial optimization problems, noise…
Faster Search of Clustered Marked States with Lackadaisical Quantum Walks
Amit Saha, Ritajit Majumdar, Debasri Saha +2
The nature of discrete-time quantum walk in the presence of multiple marked states has been studied by Nahimovs and Rivosh. They introduced an exceptional configuration of clustere…
Prediction of the final rank of Players in PUBG with the optimal number of features
Diptakshi Sen, Rupam Kumar Roy, Ritajit Majumdar +2
PUBG is an online video game that has become very popular among the youths in recent years. Final rank, which indicates the performance of a player, is one of the most important fe…
Optimizing Ansatz Design in QAOA for Max-cut
Ritajit Majumdar, Dhiraj Madan, Debasmita Bhoumik +3
Quantum Approximate Optimization Algorithm (QAOA) is studied primarily to find approximate solutions to combinatorial optimization problems. For a graph with vertices and e…
Quantum Secure Direct Communication with Mutual Authentication using a Single Basis
Nayana Das, Goutam Paul, Ritajit Majumdar
In this paper, we propose a new theoretical scheme for quantum secure direct communication (QSDC) with user authentication. Different from the previous QSDC protocols, the present…
