Development and experimental implementation of noise characterisation techniques on a superconducting quantum processor
Nelson M. M. Fernández, Francesco Grieco, Hetta Vappula +6
Noise characterisation not only enables error mitigation but also provides valuable information about the intrinsic performance of a quantum device, identifying dominant error cont…
Estimating molecular thermal averages with the quantum equation of motion and informationally complete measurements
Daniele Morrone, N. Walter Talarico, Marco Cattaneo +1
By leveraging the Variational Quantum Eigensolver (VQE), the ``quantum equation of motion" (qEOM) method established itself as a promising tool for quantum chemistry on near term q…
Quantum-centric strong and dynamical electron correlation: A resource-efficient second-order -electron valence perturbation theory formulation for near-term quantum devices
Aaron Fitzpatrick, N. Walter Talarico, Roberto Di Remigio Eikås +1
We present a measurement-cost efficient implementation of Strongly-Contracted -Electron Valence Perturbation Theory (SC-NEVPT2) for use on near-term quantum devices. At the hear…
A self-consistent field approach for the variational quantum eigensolver: orbital optimization goes adaptive
Aaron Fitzpatrick, Anton Nykänen, N. Walter Talarico +4
We present a self consistent field approach (SCF) within the Adaptive Derivative-Assembled Problem-Tailored Ansatz Variational Quantum Eigensolver (ADAPT-VQE) framework for efficie…
Quantum network medicine: rethinking medicine with network science and quantum algorithms
Sabrina Maniscalco, Elsi-Mari Borrelli, Daniel Cavalcanti +14
Scientific and technological advances in medicine and systems biology have unequivocally shown that health and disease must be viewed in the context of the interplay among multiple…
A many-body approach to transport in quantum systems: From the transient regime to the stationary state
M. Ridley, N. W. Talarico, D. Karlsson +2
We review one of the most versatile theoretical approaches to the study of time-dependent correlated quantum transport in nano-systems: the non-equilibrium Green's function (NEGF)…
Spectral properties of correlated quantum wires and carbon nanotubes within the Generalized Kadanoff-Baym Ansatz
F. Cosco, N. W. Talarico, R. Tuovinen +1
We investigate the spectral properties of an open interacting system by solving the Generalized Kadanoff-Baym Ansatz (GKBA) master equation for the single-particle density matrix,…
Study of the energy variation in many-body open quantum systems: role of interactions in the weak and strong coupling regimes
N. W. Talarico, S. Maniscalco, N. Lo Gullo
We derive an expression for the rate of change of the energy of an interacting many-body system connected to macroscopic leads. We show that the energy variation is the sum of cont…
Entanglement Protection via Periodic Environment Resetting in Continuous Time Quantum Dynamical Processes
Thomas Bullock, Francesco Cosco, Marwan Haddara +8
The temporal evolution of entanglement between a noisy system and an ancillary system is analyzed in the context of continuous time open quantum system dynamics. Focusing on a coup…
A scalable numerical approach to the solution of the Dyson equation for the non-equilibrium single-particle Green's function
N. W. Talarico, S. Maniscalco, N. Lo Gullo
In this work we present a numerical method to solve the set of Dyson-like equations arising the context of non-equilibrium Green's functions. The technique is based on the self-con…
Emergence of anomalous dynamics from the underlying singular continuous spectrum in interacting many-body systems
J. Settino, N. W. Talarico, F. Cosco +3
We investigate the dynamical properties of an interacting many-body system with a non-trivial energy potential landscape that may induce a singular continuous single-particle energ…
