Enhancing the security of coherent one-way quantum key distribution using CHSH correlations

Mahdi Shaban, Farnaz Farman, Alireza Bahrampour

The coherent one-way (COW) protocol is a quantum key distribution scheme that has attracted significant attention, leading to the development and commercialization of practical imp…

Dissipation-Induced Deviations from Kibble-Zurek Scaling in Non-Hermitian Quantum Annealing

H. Najafzadeh, S. Sadeghizade, R. Jafari +1

We revisit the quantum annealing problem in the non-Hermitian transverse-field Ising model. We determine, both analytically and numerically, the intrinsic transition probabilities…

High-Fidelity Teleportation of Continuous-Variable Quantum States Via Non-Ideal Qutrit Entangled Resources

Fatemeh Taghipoor, Mojtaba Golshani, Mostafa Motamedifar +1

Achieving near-unity fidelity in conventional continuous-variable quantum teleportation schemes based on two-mode squeezed vacuum states is fundamentally unattainable. To overcome…

Open harmonic chain without secular approximation

Melika Babakan, Fabio Benatti, Laleh Memarzadeh

We study particle and energy transport in an open quantum system consisting of a three harmonic oscillator chain coupled to thermal baths at different temperatures placed at the en…

Parallel Data Processing in Quantum Machine Learning

Sina Asadiyan Zargar, Mehdi Ramezani, Abolfazl Bahrampour +2

We propose a Quantum Machine Learning (QML) framework that applies the core design principle of quantum algorithms-superposition, oracle, and interference-to accelerate training. B…

Bending hyperplanes: nonlinear entanglement witnesses via envelopes of linear witnesses

AmirHossein Tangestaninejad, Vahid Karimipour

Entanglement witnesses (EWs) are fundamental tools for detecting entanglement. However traditional linear witnesses often fail to identify most of the entangled states. In this wor…
