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…
-QER: An Intelligent Approach towards Quantum Error Reduction
Saikat Basu, Amit Saha, Amlan Chakrabarti +1
Quantum computing has become a promising computing approach because of its capability to solve certain problems, exponentially faster than classical computers. A -qubit quantum…
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…
Local Quantum State Marking
Samrat Sen, Edwin Peter Lobo, Sahil Gopalkrishna Naik +8
We propose the task of local state marking (LSM), where some multipartite quantum states chosen randomly from a known set of states are distributed among spatially separated partie…
Creating and destroying coherence with quantum channels
Masaya Takahashi, Swapan Rana, Alexander Streltsov
The emerging quantum technologies rely on our ability to establish and control quantum systems in nonclassical states, exhibiting entanglement and quantum coherence. It is thus cru…
Following Forrelation -- Quantum Algorithms in Exploring Boolean Functions' Spectra
Suman Dutta, Subhamoy Maitra, Chandra Sekhar Mukherjee
Here we revisit the quantum algorithms for obtaining Forrelation [Aaronson et al, 2015] values to evaluate some of the well-known cryptographically significant spectra of Boolean f…
Resource theory of imaginarity: Quantification and state conversion
Kang-Da Wu, Tulja Varun Kondra, Swapan Rana +5
Complex numbers are widely used in both classical and quantum physics, and are indispensable components for describing quantum systems and their dynamical behavior. Recently, the r…
Revisiting thermodynamics in computation and information theory
Pritam Chattopadhyay, Goutam Paul
One of the primary motivations of the research in the field of computation is to optimize the cost of computation. The major ingredient that a computer needs is the energy to run a…
Maximum Violation of Monogamy of Entanglement for Indistinguishable Particles by Measures that are Monogamous for Distinguishable Particles
Goutam Paul, Soumya Das, Anindya Banerji
Two important results of quantum physics are the \textit{no-cloning} theorem and the \textit{monogamy of entanglement}. The former forbids the creation of an independent and identi…
Hyper-hybrid entanglement, indistinguishability, and two-particle entanglement swapping
Soumya Das, Goutam Paul, Anindya Banerji
Hyper-hybrid entanglement for two indistinguishable bosons has been recently proposed by Li \textit{et al.} [Y. Li, M. Gessner, W. Li, and A. Smerzi, \href{https://doi.org/10.1103/…
Secure Multi-Party Quantum Conference and Xor Computation
Nayana Das, Goutam Paul
Quantum conference is a process of securely exchanging messages between three or more parties, using quantum resources. A Measurement Device Independent Quantum Dialogue (MDI-QD) p…
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…
