Bound-state-protected phase metrology for a quantum emitter in a Su-Schrieffer-Heeger bath
Sofia Evangelou
We study local phase estimation for a single quantum emitter coupled to a bosonic Su-Schrieffer-Heeger (SSH) bath within a microscopic lattice model. Dimerization opens a central g…
Probing the limits of variational quantum algorithms for nonlinear ground states on real quantum hardware: The effects of noise
Muhammad Umer, Eleftherios Mastorakis, Sofia Evangelou +1
A recently proposed variational quantum algorithm has expanded the horizon of variational quantum computing to nonlinear physics and fluid dynamics. In this work, we probe the abil…
Quantum chaos in disordered graphene
I. Amanatidis, S. N. Evangelou
We have studied numerically the statistics for electronic states (level-spacings and participation ratios) from disordered graphene of finite size, described by the aspect ratio $W…
Quantum Walks on a Random Environment
Yue Yin, D. E. Katsanos, S. N. Evangelou
Quantum walks are considered in a one-dimensional random medium characterized by static or dynamic disorder. Quantum interference for static disorder can lead to Anderson localizat…
Environment-Mediated Quantum State Transfer
Yue Yin, S. N. Evangelou
We propose a scheme for quantum state transfer(QST) between two qubits which is based on their individual interaction with a common boson environment. The corresponding single mode…
Quantum correlations from Brownian diffusion of chaotic level-spacings
S. N. Evangelou, D. E. Katsanos
Quantum chaos is linked to Brownian diffusion of the underlying quantum energy level-spacing sequences. The level-spacings viewed as functions of their order execute random walks w…
