Scaling of entanglement entropy and correlations in the variable-range extended Ising model
Harikrishnan K J, Debasis Sadhukhan, Amit Kumar Pal
We study the two-point correlation functions and the bipartite entanglement in the ground state of the exactly-solvable variable-range extended Ising model of qubits in the presenc…
Scaling of Quantum Resources for Simulating a Long-Range System
Tanya Keshari, Debasis Sadhukhan
We simulate a long-range extended Ising model in one dimension using a hybrid quantum algorithm, namely Variational Quantum Eigensolver (VQE). In this quantum simulation, we invest…
Mimicking quantum correlation of a long-range Hamiltonian by finite-range interactions
Leela Ganesh Chandra Lakkaraju, Srijon Ghosh, Debasis Sadhukan +1
The quantum long-range extended Ising model possesses several striking features that cannot be observed in the corresponding short-range model. We report that the pattern obtained…
Restricted Randomized Benchmarking with Universal Gates of Fixed Sequence Length
Mohsen Mehrani, Kasra Masoudi, Rawad Mezher +2
The standard randomized benchmarking protocol requires access to often complex operations that are not always directly accessible. Compiler optimization does not always ensure equa…
