How NOT to build control-target gates in semiconductor quantum dots and beyond
Roman Korol, John Nichol, Ignacio Franco
Universal quantum computation requires single-qubit control together with at least one entangling two-qubit gate. CNOT and CROT gates are two famous examples of such gates, wherein…
TENSO: Software Package for Numerically Exact Open Quantum Dynamics Based on Efficient Tree Tensor Network Decomposition of the Hierarchical Equations of Motion
Juan C. Rodriguez-Betancourt, Michelle C. Anderson, Luchang Niu +2
TENSO is a versatile and powerful open-source software package for numerically exact simulations of the dynamics of quantum systems immersed in structured thermal environments. It…
Light-Matter Interactions Beyond the Dipole Approximation in Extended Systems Without Multipole Expansion
Rishabh Dora, Roman Korol, Vishal Tiwari +2
We present a general theoretical framework to capture light-matter interactions beyond the electric-dipole approximation (EDA), applicable to extended nano- and microscale material…
Comparison between explicit and implicit discretization strategies for a dissipative thermal environment
Xinxian Chen, Ignacio Franco
We investigate strategies for simulating open quantum systems coupled to dissipative baths by comparing explicit wave function-based discretization [via multi-layer multi-configura…
Tree tensor network hierarchical equations of motion based on time-dependent variational principle for efficient open quantum dynamics in structured thermal environments
Xinxian Chen, Ignacio Franco
We introduce an efficient method TTN-HEOM for exactly calculating the open quantum dynamics for driven quantum systems interacting with highly structured bosonic baths by combining…
High-frequency tails in spectral densities
Roman Korol, Xinxian Chen, Ignacio Franco
Recent advances in numerically exact quantum dynamics methods have brought the dream of accurately modeling the dynamics of chemically complex open systems within reach. Path-integ…
