Resource-efficient Variational Compilation of Block-Encodings
Leon Rullkötter, Sebastian Weber, Vamshi Mohan Katukuri +2
Block-encoding operators are one of the essential components in quantum algorithms based on Quantum Signal Processing. Their gate complexity largely determines the overall gate com…
Optimizing Superconducting Qubit Performance: A Theoretical Framework for Design, Analysis, and Calibration
Sirshi S Ram, Muralikrishna Molli, Vamshi Mohan Katukuri +1
Designing a qubit architecture is one of the most critical challenges in achieving scalable and fault-tolerant quantum computing as the performance of a quantum computer is heavily…
Ferromagnetic domains in the large- Hubbard model with a few holes: an FCIQMC study
Sujun Yun, Werner Dobrautz, Hongjun Luo +3
Two-dimensional Hubbard lattices with two or three holes are investigated as a function of in the large- limit. In the so-called Nagaoka limit (one-hole system at infinite $…
Ab initio wavefunction analysis of electron removal quasi-particle state of NdNiO with fully correlated quantum chemical methods
Vamshi M. Katukuri, Nikolay A. Bogdanov, Ali Alavi
The discovery of superconductivity in hole-doped infinite-layer NdNiO -- a transition metal (TM) oxide that is both isostructural and isoelectronic to cuprate superconductors -…
Combined unitary and symmetric group approach applied to low-dimensional spin systems
Werner Dobrautz, Vamshi M. Katukuri, Nikolay A. Bogdanov +3
A novel combined unitary and symmetric group approach is used to study the spin- Heisenberg model and related Fermionic systems in a spin-adapted representation, using…
Charge ordering in Ir dimers in the ground state of BaAlIrO
Vamshi M. Katukuri, Xingye Lu, D. E. McNally +8
It has been well established experimentally that the interplay of electronic correlations and spin-orbit interactions in Ir and Ir oxides results in insulating J$_{\r…
