QuTiP 5: The Quantum Toolbox in Python
Neill Lambert, Eric Giguère, Paul Menczel +15
QuTiP, the Quantum Toolbox in Python, has been at the forefront of open-source quantum software for the past 13 years. It is used as a research, teaching, and industrial tool, and…
Diagnosing quantum chaos with out-of-time-ordered-correlator quasiprobability in the kicked-top model
José Raúl González Alonso, Nathan Shammah, Shahnawaz Ahmed +2
While classical chaos has been successfully characterized with consistent theories and intuitive techniques, such as with the use of Lyapunov exponents, quantum chaos is still poor…
Pulse-level noisy quantum circuits with QuTiP
Boxi Li, Shahnawaz Ahmed, Sidhant Saraogi +4
The study of the impact of noise on quantum circuits is especially relevant to guide the progress of Noisy Intermediate-Scale Quantum (NISQ) computing. In this paper, we address th…
Exceptional Point and Cross-Relaxation Effect in a Hybrid Quantum System
Guo-Qiang Zhang, Zhen Chen, Da Xu +7
Exceptional points (EPs) are exotic degeneracies of non-Hermitian systems, where the eigenvalues and the corresponding eigenvectors simultaneously coalesce in parameter space, and…
Symmetries and conserved quantities of boundary time crystals in generalized spin models
Giulia Piccitto, Matteo Wauters, Franco Nori +1
We investigate how symmetries and conserved quantities relate to the occurrence of the boundary time crystal (BTC) phase in a generalized spin model with Lindblad dissipation. BTCs…
Dissipation-induced bistability in the two-photon Dicke model
Louis Garbe, Peregrine Wade, Fabrizio Minganti +3
The Dicke model is a paradigmatic quantum-optical model describing the interaction of a collection of two-level systems with a single bosonic mode. Effective implementations of thi…
Multielectron Ground State Electroluminescence
Mauro Cirio, Nathan Shammah, Neill Lambert +2
The ground state of a cavity-electron system in the ultrastrong coupling regime is characterized by the presence of virtual photons. If an electric current flows through this syste…
Open quantum systems with local and collective incoherent processes: Efficient numerical simulation using permutational invariance
Nathan Shammah, Shahnawaz Ahmed, Neill Lambert +2
The permutational invariance of identical two-level systems allows for an exponential reduction in the computational resources required to study the Lindblad dynamics of coupled sp…
Superradiance with local phase-breaking effects
Nathan Shammah, Neill Lambert, Franco Nori +1
We study the superradiant evolution of a set of two-level systems spontaneously radiating under the effect of phase-breaking mechanisms. We investigate the dynamics generated b…
Theory of intersubband resonance fluorescence
Nathan Shammah, Simone De Liberato
The fluorescence spectrum of a strongly pumped two level system is characterised by the Mollow triplet that has been observed in a variety of systems, ranging from atoms to quantum…
Quantifying the nonlinearity of a quantum oscillator
Matteo G. A. Paris, Marco G. Genoni, Nathan Shammah +1
We address the quantification of nonlinearity for quantum oscillators and introduce two measures based on the properties of the ground state rather than on the form of the potentia…
Terahertz emission from AC Stark-split asymmetric intersubband transitions
Nathan Shammah, Chris C. Phillips, Simone De Liberato
Transitions between the two states of an AC Stark-split doublet are forbidden in centro-symmetric systems, and thus almost impossible to observe in experiments performed with atomi…
