Kitaev Quantum Batteries: Super-Extensive Scaling of Ergotropy in 1D Spin Chain
Asad Ali, Samira Elghaayda, Saif Al-Kuwari +7
We investigate the performance of a novel model based on a one-dimensional (1D) spin- Heisenberg quantum chain, also known as 1D Kitaev chain, as a working medium fo…
Harnessing coherence generation for precision single- and two-qubit quantum thermometry
Youssef Aiache, Abderrahim El Allati, Khadija El Anouz
Quantum probes, such as single- and two-qubit probes, can accurately measure the temperature of a bosonic bath. The current investigation assesses the precision of temperature esti…
Optimal Superdense Coding Capacity in the Non-Markovian Regime
Y. Aiache, S. Al-Kuwari, K. El Anouz +1
Superdense coding is a significant technique widely used in quantum information processing. Indeed, it consists of sending two bits of classical information using a single qubit, l…
Teleportation two-qubit state by using two different protocols
K. El Anouz, A. El Allati, N. Metwally
In this contribution, two versions of teleportation protocol are considered, based on either using a single or two copies of entangled atom-field state, respectively. It is shown t…
Dual Non-local Cnot gate
Chaibata Seida, Abderrahim El Allati, Khadija El Anouz
Distant quantum control via quantum gates represents an essential step toward realizing distributed quantum networks. An efficient theoretical protocol for the dual non-local imple…
Strong quantum correlation in a pair hybrid optomechanical cavities
Khadija El Anouz, Abderrahim El Allati, Farhan Saif
We show the quantum correlation between two coupled hybrid optomechanical cavities by quantifying the non-classical correlation using Gaussian quantum discord. This involves analyz…
