Gottesman-Kitaev-Preskill error-correction with decohered resources
Rajendra S. Bhati, T. Bazylewicz, Jarosław K. Korbicz
Teleportation-based Gottesman-Kitaev-Preskill (GKP) error correction typically assumes a decoherence-free GKP ancilla Bell pair, an idealization that is difficult to reconcile with…
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…
No contextual advantage in non-paradoxical scenarios of two state vector formalism
Jaskaran Singh, Rajendra Singh Bhati, Arvind
The two state vector formalism (TSVF) was proposed by Aharonov, Bergmann, and Lebowitz (ABL) to provide a way for the counterfactual assignment of the probabilities of outcomes of…
Revealing quantum contextuality using a single measurement device
Jaskaran Singh, Rajendra Singh Bhati, Arvind
In this work we analyse the notion of measurement non-contextuality (MNC) and identify contextual scenarios which involve sequential measurements of only a single measurement devic…
Do weak values capture the complete truth about the past of a quantum particle?
Rajendra Singh Bhati, Arvind
Weak values inferred from weak measurements have been proposed as a tool to investigate trajectories of pre- and post-selected quantum systems. Are the inferences drawn from the we…
