Local entanglement transfer to multiple pairs of spatially separated observers

Tanmoy Mondal, Kornikar Sen, Chirag Srivastava +1

Entanglement is an advantageous but at the same time a costly resource utilized in various quantum tasks. For an efficient usage and deployment of entanglement, we envisage the sce…

Auxiliary-assisted energy distillation from quantum batteries

Paranjoy Chaki, Aparajita Bhattacharyya, Kornikar Sen +1

We discuss the idea of extracting energy from a quantum battery, applying a projective measurement on an auxiliary system. The battery is initially connected to the auxiliary syste…

Noncompletely Positive Quantum Maps Enable Efficient Local Energy Extraction in Batteries

Aparajita Bhattacharyya, Kornikar Sen, Ujjwal Sen

Energy extraction from quantum batteries by means of completely positive trace-preserving (CPTP) maps leads to the concept of CPTP-local passive states, which identify bipartite st…

Duality between quantum channels and super-channels is basis-dependent

Sohail, Sahil, Ritabrata Sengupta +1

The complete positivity vs positivity correspondence in the Choi-Jamiołkowski-Kraus-Sudarshan quantum channel-state isomorphism depends on the choice of basis. Instead of the "cano…

Effects of noise on performance of Bernstein-Vazirani algorithm

Archi Gupta, Priya Ghosh, Kornikar Sen +1

The Bernstein-Vazirani (BV) algorithm offers exceptional accuracy in finding the hidden bit string of a function. We explore how the algorithm performs in real-world situations whe…

Entanglement is indispensable for masking arbitrary set of quantum states

Debarupa Saha, Priya Ghosh, Ujjwal Sen

We question the role of entanglement in masking quantum information contained in a set of mixed quantum states. We first show that a masker that can mask any two single-qubit pure…
