Unconditionally superposition-robust entangled state in all multiparty quantum systems
Swati Choudhary, Ujjwal Sen, Saronath Halder
We investigate the inseparability of states generated by superposition of a multipartite pure entangled state with a product state. In particular, we identify specific multipartite…
Sample Complexity of Black Box Work Extraction
Shantanav Chakraborty, Siddhartha Das, Arnab Ghorui +2
Extracting work from a physical system is one of the cornerstones of quantum thermodynamics. The extractable work, as quantified by ergotropy, necessitates a complete description o…
Unstructured Adiabatic Quantum Optimization: Optimality with Limitations
Arthur Braida, Shantanav Chakraborty, Alapan Chaudhuri +4
In the circuit model of quantum computing, amplitude amplification techniques can be used to find solutions to NP-hard problems defined on -bits in time …
Teleportation fidelity of quantum repeater networks
Ganesh Mylavarapu, Subrata Ghosh, Chittaranjan Hens +2
We show that the average of the maximum teleportation fidelities between all pairs of nodes in a large quantum repeater network is a measure of the resourcefulness of the network a…
On fully entangled fraction and quantum conditional entropies for states with maximally mixed marginals
Komal Kumar, Indranil Chakrabarty, Nirman Ganguly
The fully entangled fraction (FEF) measures the proximity of a quantum state to maximally entangled states. FEF , in systems is a significant benchmark…
Effect of measurements on quantum speed limit
Abhay Srivastav, Vivek Pandey, Arun K Pati
Given the initial and final states of a quantum system, the speed of transportation of state vector in the projective Hilbert space governs the quantum speed limit. Here, we ask th…
KANQAS: Kolmogorov-Arnold Network for Quantum Architecture Search
Akash Kundu, Aritra Sarkar, Abhishek Sadhu
Quantum architecture Search (QAS) is a promising direction for optimization and automated design of quantum circuits towards quantum advantage. Recent techniques in QAS emphasize M…
Qubit frugal entanglement determination with the deep multi-scale entanglement renormalization ansatz
Kushagra Garg, Zeeshan Ahmed, Andreas Thomasen
We study the deep multi-scale entanglement renormalization ansatz (DMERA) on quantum hardware and the causal cone of a subset of the qubits which make up the ansatz. This causal co…
Causal and Non-Causal Revivals of Information: A New Regime of Non-Markovianity in Quantum Stochastic Processes
Francesco Buscemi, Rajeev Gangwar, Kaumudibikash Goswami +5
The study of information revivals, witnessing the violation of certain data-processing inequalities, has provided an important paradigm in the study of non-Markovian quantum stocha…
Maximal Secret Reconstruction, Teleportation and Bell's Inequality
Pratishtha Abrol, Pahulpreet Singh, Indranil Chakrabarty
A tripartite state is said to be a potential resource for secret sharing if the state imposes restrictions on the teleportation fidelity of the bipartite dealer--reconstructor and…
A quantum information theoretic analysis of reinforcement learning-assisted quantum architecture search
Abhishek Sadhu, Aritra Sarkar, Akash Kundu
In the field of quantum computing, variational quantum algorithms (VQAs) represent a pivotal category of quantum solutions across a broad spectrum of applications. These algorithms…
Fundamental limitations on the recoverability of quantum processes
Sohail, Vivek Pandey, Uttam Singh +1
Quantum information processing and computing tasks can be understood as quantum networks, comprising quantum states and channels and possible physical transformations on them. It i…
Cost of quantum secret key
Karol Horodecki, Leonard Sikorski, Siddhartha Das +1
In this paper, we develop the resource theory of quantum secret key. Operating under the assumption that entangled states with zero distillable key do not exist, we define the key…
Using Quantum Switches to Mitigate Noise in Grover's Search Algorithm
Suryansh Srivastava, Arun K. Pati, Samyadeb Bhattacharya +1
Grover's quantum search algorithm promises a quadratic speedup for unstructured search over its classical counterpart. But this advantage is affected by noise acting on the search…
