Blind-spots of Randomized Benchmarking Under Temporal Correlations
Varun Srivastava, Abhinash Kumar Roy, Soumik Mahanti +3
Randomized benchmarking (RB) is a widely adopted protocol for estimating the average gate fidelity in quantum hardware. However, its standard formulation relies on the assumption o…
A Geometry of entanglement and entropy
Ramita Sarkar, Soumik Mahanti, Prasanta K. Panigrahi
This paper explores the fundamental relationship between the geometry of entanglement and von Neumann entropy, shedding light on the intricate nature of quantum correlations. We pr…
Semi-device-independent certification of quantum non-Markovianity using sequential Random Access Codes
Abhinash Kumar Roy, Varun Srivastava, Soumik Mahanti +2
The characterization of multi-time correlations in open quantum systems is of fundamental importance. In this work, we investigate multi-time processes using the process matrix for…
Geometric genuine multipartite entanglement for four-qubit systems
Ansh Mishra, Soumik Mahanti, Abhinash Kumar Roy +1
Xie and Eberly introduced a genuine multipartite entanglement (GME) measure `concurrence fill'(\textit{Phys. Rev. Lett., \textbf{127}, 040403} (2021)) for three-party systems. It i…
Classification and Quantification of Entanglement Through Wedge Product and Geometry
Soumik Mahanti, Sagnik Dutta, Prasanta K. Panigrahi
Wedge product of post-measurement vectors leading to an `area' measure of the parallelogram has been shown to give the generalized I-concurrence measure of entanglement. Extending…
'Complementarity' in paraxial and non-paraxial optical beams
Abhinash Kumar Roy, Nitish Kumar Chandra, Soumik Mahanti +1
Establishing the correspondence of two dimensional paraxial and three dimensional non-paraxial optical beams with the qubit and qutrit systems respectively, we derive a complementa…
Quantum Robots Can Fly; Play Games: An IBM Quantum Experience
Soumik Mahanti, Santanu Das, Bikash K. Behera +1
Quantum Robot is an excellent future application that can be achieved with the help of a quantum computer. As a practical example, quantum controlled Braitenberg vehicles proposed…
