Tradeoff between noise and banding in a quantum adder with qudits
Gaurang Agrawal, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Quantum addition based on the quantum Fourier transform can be an integral part of a quantum circuit and proved to be more efficient than the existing classical ripple carry adder.…
Quantum resources in Harrow-Hassidim-Lloyd algorithm
Pradeep Kumar, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
Quantum algorithms have the ability to reduce runtime for executing tasks beyond the capabilities of classical algorithms. Therefore, identifying the resources responsible for quan…
Quantum-enhanced sensing with variable-range interactions
Monika Mothsara, Leela Ganesh Chandra Lakkaraju, Srijon Ghosh +1
The typical bound on parameter estimation, known as the standard quantum limit (SQL), can be surpassed by exploiting quantum resources such as entanglement. To estimate the magneti…
Recognizing critical lines via entanglement in non-Hermitian systems
Keshav Das Agarwal, Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju +1
The non-Hermitian model exhibits counterintuitive phenomena that are not observed in the Hermitian counterparts. To probe the competition between non-Hermitian and Hermitian intera…
Framework of dynamical transitions from long-range to short-range quantum systems
Leela Ganesh Chandra Lakkaraju, Srijon Ghosh, Debasis Sadhukhan +1
A quantum many-body system undergoes phase transitions of distinct species with variations of local and global parameters. We propose a framework in which a dynamical quantity can…
