Port-based teleportation under pure-dephasing decoherence
Rajendra S. Bhati, Michał Studziński, Jarosław K. Korbicz
We study deterministic port based teleportation in the presence of noise affecting both the entangled resource state and the measurement process. We focus on a physically motivated…

Security in a prepare-and-measure quantum key distribution protocol when the receiver uses weak values to guess the sender's bits
Rajendra Singh Bhati
The weak values and weak measurement formalism were initially limited to pure states, which were later extended to mixed states, leading to intriguing applications in quantum infor…

Quantum operations restricted by no faster-than-light communication principle and generic emergence of objectivity in position basis
Rajendra Singh Bhati, Arvind
The emergence of the objective classical world from the quantum behavior of microscopic constituents is not fully understood. Models based on decoherence and the principle of quant…
