Statistical mechanics in continuous space with tensor network methods

Gunhee Park, Tomislav Begušić, Si-Jing Du +2

Tensor network (TN) methods are well established for computing partition functions in statistical mechanics, though this use has traditionally been limited to lattice models. We ex…

Phase-sensitive representation of Majorana stabilizer states

Tomislav Begušić, Garnet Kin-Lic Chan

Stabilizer states hold a special place in quantum information science due to their connection with quantum error correction and quantum circuit simulation. In the context of classi…

Digital quantum magnetism on a trapped-ion quantum computer

Reza Haghshenas, Eli Chertkov, Michael Mills +56

Digital quantum matter -- realized when discrete quantum gates approximate continuous time evolution -- is susceptible to heating into chaotic, structureless states. If digitizatio…

Fast classical simulation of evidence for the utility of quantum computing before fault tolerance

Tomislav Begušić, Garnet Kin-Lic Chan

We show that a classical algorithm based on sparse Pauli dynamics can efficiently simulate quantum circuits studied in a recent experiment on 127 qubits of IBM's Eagle processor [N…

On-the-fly ab initio semiclassical evaluation of electronic coherences in polyatomic molecules reveals a simple mechanism of decoherence

Nikolay V. Golubev, Tomislav Begušić, Jiří Vaníček

Irradiation of a molecular system by an intense laser field can trigger dynamics of both electronic and nuclear subsystems. The lighter electrons usually move on much faster, attos…

On-the-fly ab initio three thawed Gaussians approximation: A semiclassical approach to Herzberg-Teller spectra

Tomislav Begušić, Aurélien Patoz, Miroslav Šulc +1

Evaluation of symmetry-forbidden or weakly-allowed vibronic spectra requires treating the transition dipole moment beyond the Condon approximation. To include vibronic spectral fea…
