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…
Preservation of entanglement in local noisy channels
Priya Ghosh, Kornikar Sen, Ujjwal Sen
Entanglement subject to noise can not be shielded against decaying. But, in case of many noisy channels, the degradation can be partially prevented by using local unitary operation…
Response to glassy disorder in coin on spread of quantum walker
Priya Ghosh, Kornikar Sen, Ujjwal Sen
We analyze the response to incorporation of glassy disorder in the coin operation of a discrete-time quantum walk in one dimension. We find that the ballistic spread of the disorde…
