Steady states and oscillation modes of two driven dissipative oscillators with non-Hermitian coupling

Sahel Ashhab, Aakanksha Sud, Shunsuke Fukami

We analyze the dynamics of two harmonic oscillators with nonlinear, non-Hermitian coupling between them. Specifically, we consider a synthetic antiferromagnet composed of two ferro…

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…
