Advances in Quantum Theory [PDF]
, 2012 The quantum theory is the first theoretical approach that helps one to successfully understand the atomic and sub-atomic worlds which are too far from the cognition based on the common intuition or the experience of the daily-life.

Quantum information theory and the foundations of quantum mechanics [PDF]
, 2004 This thesis is a contribution to the debate on the implications of quantum information theory for the foundational problems of quantum mechanics. In Part I an attempt is made to shed some light on the nature of information and quantum information theory.

Comment on ‘Single particle nonlocality with completely independent reference states’
New Journal of Physics, 2022 We comment on the purported violation of local realism, by a single photon induced correlations between homodyne detectors, which one can find in: (2008) New J. Phys. 10 113024 [arXiv: 0807.0109 ].

npj Quantum Information, 2022 The problem of achieving security of device-independent (or semi-device-independent) cryptography (for quantum key distribution and randomness generation) against the most general no-signaling adversaries has remained open.

Bipartite nonlocality with a many-body system
New Journal of Physics, 2019 We consider a bipartite scenario where two parties hold ensembles of 1/2-spins which can only be measured collectively. We give numerical arguments supporting the conjecture that in this scenario no Bell inequality can be violated for arbitrary numbers ...

Unfree gauge symmetry in the BV formalism
European Physical Journal C: Particles and Fields, 2019 The BV formalism is proposed for the theories where the gauge symmetry parameters are unfree, being constrained by differential equations.

Non-isometric codes for the black hole interior from fundamental and effective dynamics
Journal of High Energy Physics, 2023 We introduce a new holographic map for encoding black hole interiors by including both fundamental and effective dynamics. This holographic map is constructed by evolving a state in the effective, semiclassical gravity description of the interior ...

Post-quantum steering is a stronger-than-quantum resource for information processing
npj Quantum Information, 2022 We present the first instance where post-quantum steering is a stronger-than-quantum resource for information processing – remote state preparation.

Proposal for demonstration of long-range cluster state entanglement in the presence of photon loss
APL Photonics, 2017 Photonic cluster states are a crucial resource for optical quantum computing. Recently a quantum dot single photon source has been demonstrated to produce strings of single photons in a small linear cluster state.
