Security of deterministic key distribution with higher-dimensional systems
Abhishek Muhuri, Ayan Patra, Rivu Gupta +2
We analyze the security of two-way quantum key distribution using arbitrary finite-dimensional systems, considering both individual and collective eavesdropping attacks, without th…
Role of quantum state texture in probing resource theories and quantum phase transition
Ayan Patra, Tanoy Kanti Konar, Pritam Halder +1
Building on the recently developed quantum state texture resource theory, we exhibit that the difference between maximum and minimum textures is a valid purity monotone in any dime…
Perfect transfer of arbitrary continuous variable states across optical waveguide lattices
Tonipe Anuradha, Ayan Patra, Rivu Gupta +1
We demonstrate that perfect state transfer can be achieved in an optical waveguide lattice governed by a Hamiltonian with modulated nearest-neighbor couplings. In particular, we re…
Coherence measure of ensembles with nonlocality without entanglement
Ayan Patra, Shiladitya Mal, Aditi Sen De
Irreversibility between preparation and discrimination processes is manifested in the indistinguishability of orthogonal product states via local operations and classical communica…
Sequential information theoretic protocols in continuous variable systems
Sudipta Das, Ayan Patra, Rivu Gupta +2
In order to enable the sequential implementation of quantum information theoretic protocols in the continuous variable framework, we propose two schemes for resource reusability, r…
Limits on broadcasting non-stabilizerness through unrestricted operations
Rivu Gupta, Tanoy Kanti Konar, Ayan Patra +1
In the resource theory of non-stabilizerness, we prove that stabilizer operations cannot replicate or broadcast the "magic" resource of all quantum states in an arbitrary finite di…
