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…
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…
Robust purely optical signatures of Floquet states in laser-dressed crystals
Vishal Tiwari, Roman Korol, Ignacio Franco
Strong light-matter interactions can create non-equilibrium materials with on-demand novel functionalities. For periodically driven solids, the Floquet theorem provides the natural…
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…
