Entangling Power and Symmetries in the Quantum Rabi Model
Ian Low, Jens Koch, Sahel Ashhab
The quantum Rabi model is a standard effective Hamiltonian in studies of light-matter interaction, capturing the simplest nontrivial setting in which a qubit couples to a single ha…
Is the most random pattern random? Maximizing localization in a two-dimensional lattice with engineered disorder
Morgan Berkane, Sahel Ashhab
We investigate localization in two models: a single particle in a two-dimensional square lattice described by the tight binding Hamiltonian, and a two-dimensional square qubit latt…
Computational and physical complexity of synthesizing random multi-qudit quantum states and unitary operators
Sahel Ashhab, Bora Basyildiz
We analyze the complexity of synthesizing random states and unitary operators in a multi-qudit system in two paradigms. In one case, we consider the situation in which we manipulat…
Reinforcement Learning for Robust Calibration of Multi-Qudit Quantum Gates
Amine Jaouadi, Sahel Ashhab
Higher-dimensional quantum systems, such as qudits, offer architectural and algorithmic advantages over qubits, but their increased spectral crowding and limited controllability re…
Digital Quantum Simulation of the Holstein-Primakoff Transformation on Noisy Qubits
Kelvin Yip, Alessandro Monteros, Sahel Ashhab +1
Quantum simulation of many-body systems offers a powerful approach to exploring collective quantum dynamics beyond classical computational reach. Although spin and fermionic models…
Reply to Comment on "Properties and dynamics of generalized squeezed states"
Sahel Ashhab, Mohammad Ayyash
In our paper [1], our numerical simulations showed that, unlike displacement and conventional squeezing, higher-order squeezing exhibits oscillatory dynamics. Subsequently, Gordill…
Fractional squeezing: spectra and dynamics from generalized squeezing Hamiltonian with fractional orders
Sahel Ashhab
We generalize the generalized-squeezing problem to include fractional values of the squeezing order . This approach allows us to determine the locations of critical points at wh…
