Tensor-Train Thermo-Field Memory Kernels for Generalized Quantum Master Equations

Ellen Mulvihill (Batista Lab)

The tutorial focuses on benchmark quantum simulations of electronic dynamics in a spin-boson model system described by various types of GQMEs. Exact memory kernels and inhomogeneous terms are obtained from short-time quantum-mechanically exact TT-TFD simulations and are compared with those obtained from an approximate linearized semiclassical method, allowing for assessment of the accuracy of these approximate memory kernels and inhomogeneous terms, accompanied by Jupyter notebooks.

Tensor Train Tutorial

The goal of this tutorial is to get a quick start on the TT Toolbox for fast multilinear algebra computations. Here, we introduce the basic routines for multidimensional array operations in TT-format with examples, including a presentation based on the quick start document developed by Ivan Oseledets, Sergey Dolgov, Vladimir Kazeev, Olga Lebedeva, Thomas Mach, and developments at Yale by the Batista group.

Electronic Structure on Quantum Computer with VQE, ADAPT-VQE and Application to Custom Hamiltonian Tutorial

Delmar Cabral and Brandon Allen (Batista Group)

A quantum computer can encode information in terms of | 0 ⟩ and | 1 ⟩ states, but also allows entanglement between each of the states. This entanglement is beneficial to chemistry problems as electrons interact with other electrons and these interactions are often correlated and an important factor in molecular properties. Thus, using a quantum computer framework to solve chemical problems may allow more efficient calculations for properties of chemical interest and higher accuracy.

Spectral Kissing and Excited State Quantum Phase Transitions

Santos and Batista Labs

Transmon qubits, central to quantum computing, also serve as versatile nonlinear oscillators for exploring physics. They simulate excited state quantum phase transitions (ESQPTs), observed through spectral kissing in driven SNAIL-transmons. ESQPT dynamics involve exponential growth of correlators, periodic revivals, and slow survival probability evolution. These findings are accessible in current superconducting circuits, relevant for cold atom and ion trap experiments.
