A method of enciphering quantum states [PDF]

open access: yes, 2000
In this paper, we propose a method of enciphering quantum states of two-state systems (qubits) for sending them in secrecy without entangled qubits shared by two legitimate users (Alice and Bob). This method has the following two properties.

Linearization (in)stabilities and crossed products

open access: yesJournal of High Energy Physics
Modular crossed product algebras have recently assumed an important role in perturbative quantum gravity as they lead to an intrinsic regularization of entanglement entropies by introducing quantum reference frames (QRFs) in place of explicit regulators.

Role of Qubits in Quantum Entanglement and Quantum Teleportation

open access: yesMathematics
A qubit is an exhibition of quantum entanglement and a key element in the quantum teleportation process. In this paper, we review the role of qubits in quantum entanglement and quantum teleportation.

Population rate of quantum states and the reverse of the arrow of time

open access: yesNova Scientia, 2022
Recently it has been pointed out that an outstanding application of an IBM quantum computer is to reverse the arrow of time (Lesovik et al., 2019). It is explored such a possibility in a two qubits system coupled to a common structured reservoir at zero

First principles study of charge diffusion between proximate solid state qubits and its implications on sensor applications

open access: yes, 2018
Solid state qubits from paramagnetic point defects in solids are promising platforms to realize quantum networks and novel nanoscale sensors. Recent advances in materials engineering make possible to create proximate qubits in solids that might interact ...

Symmetry sectors in chord space and relational holography in the DSSYK. Lessons from branes, wormholes, and de Sitter space

open access: yesJournal of High Energy Physics
In holography, gauging symmetries of the boundary theory leads to important modifications in the bulk. In this work, we study constraints to gauge symmetry sectors in the chord Hilbert space of the double-scaled SYK (DSSYK) with matter, and we connect ...

Thermal entanglement in the three-qubit Tavis-Cummings model with Kerr nonlinearity

open access: yesКомпьютерная оптика
We obtained a solution of the Liouville equation for a system of three identical qubits interacting without detuning with a thermal field of a cavity with a Kerr medium, for two type of initial pure genuine W-entangled qubits states.

Entangled webs: Tight bound for symmetric sharing of entanglement

open access: yes, 2000
Quantum entanglement cannot be unlimitedly shared among arbitrary number of qubits. Larger the number of entangled pairs in an N-qubit system, smaller the degree of bi-partite entanglement is. We analyze a system of N qubits in which an arbitrary pair of
