Tomiyama-type maps with a diagonal perturbation
Anindita Bera, Bihalan Bhattacharya, Dariusz Chruściński
We investigate a two-parameter family of linear maps on matrix algebras, constructed as diagonal perturbations of classical Tomiyama maps. Employing the Choi matrix method alongsid…
Estimation of trace distance between two arbitrary quantum states
Sanchita Ghosh, Anumita Mukhopadhyay, Anindita Bera +2
When it comes to discriminating between two quantum states, trace distance is one of the well-known metrics used in quantum computation and quantum information theory. While there…
Practical and Efficient Verification of Entanglement with Incomplete Measurement Settings
Jiheon Seong, Jin-Woo Kim, Seungchan Seo +6
In this work, we present a practical and efficient framework for verifying entangled states when only a tomographically incomplete measurement setting is available-specifically, wh…
Mirrored Entanglement Witnesses for Multipartite and High-Dimensional Quantum Systems
Jiheon Seong, Anindita Bera, Beatrix C. Hiesmayr +2
Entanglement witnesses (EWs) are a versatile tool to detect entangled states and characterize related properties of entanglement in quantum information theory. A witness corres…
Entanglement detection via third-order local invariants from randomized measurements
Giovanni Scala, Anindita Bera, Gniewomir Sarbicki
We compute all third-order local invariants accessible via randomised measurements and employ them to derive separability criteria. The reconstruction of the invariants yields expe…
A mirrored pair of optimal non-decomposable entanglement witnesses for two qudits does exist
Dariusz Chruściński, Anindita Bera, Joonwoo Bae +1
Two approaches can be utilized to handle the separability problem, finding out whether a given bipartite qudit state is separable or not: a direct procedure on the state space or t…
