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…

Exclusion principle for nonlocal advantage of quantum coherence
Priya Ghosh, Mahasweta Pandit, Chirag Srivastava +1
Coherences in mutually unbiased bases of states of an isolated quantum system follow a complementarity relation. The nonlocal advantage of quantum coherence (NAQC), defined in a bi…
