Fast, accurate, high-resolution simulation of large-scale Fermi-Hubbard models on a digital quantum processor
Gavin S. Hartnett, Khadijeh Sona Najafi, Aleksei Khindanov +5
We report experimental digital quantum simulation of the one-dimensional Fermi-Hubbard model on a superconducting quantum processor at a scale beyond the reach of exact statevector…
Heterogeneous architectures enable a 138x reduction in physical qubit requirements for fault-tolerant quantum computing under detailed accounting
Pranav S. Mundada, Aleksei Khindanov, Yulun Wang +5
Quantum computer hardware is predicted to scale over hundreds of thousands of qubits coming online in the next decade. Despite significant theoretical and experimental QEC progress…
Quantum-Classical Embedding via Ghost Gutzwiller Approximation for Enhanced Simulations of Correlated Electron Systems
I-Chi Chen, Aleksei Khindanov, Carlos Salazar +6
Simulating correlated materials on present-day quantum hardware remains challenging due to limited quantum resources. Quantum embedding methods offer a promising route by reducing…
Observable Measurement-Induced Transitions
Aleksei Khindanov, Igor L. Aleiner, Lara Faoro +1
One of the main postulates of quantum mechanics is that measurements destroy quantum coherence (wave function collapse). Recently it was discovered that in a many-body system dilut…
Minimally Entangled Typical Thermal States for Classical and Quantum Simulation of 1+1-Dimensional Lattice Gauge Theory at Finite Temperature and Density
I-Chi Chen, João C. Getelina, Klée Pollock +4
Simulating strongly coupled gauge theories at finite temperature and density is a longstanding challenge in nuclear and high-energy physics that also has fundamental implications f…
Robust preparation of ground state phases under noisy imaginary time evolution
Aleksei Khindanov, Yongxin Yao, Thomas Iadecola
Non-unitary state preparation protocols such as imaginary time evolution (ITE) offer substantial advantages relative to unitary ones, including the ability to prepare certain long-…
Influence of disorder on antidot vortex Majorana states in 3D topological insulators
Rafał Rechciński, Aleksei Khindanov, Dmitry I. Pikulin +5
Topological insulator/superconductor two-dimensional heterostructures are promising candidates for realizing topological superconductivity and Majorana modes. In these systems, a v…
Topological superconductivity in nanowires proximate to a diffusive superconductor-magnetic insulator bilayer
Aleksei Khindanov, Jason Alicea, Patrick Lee +2
We study semiconductor nanowires coupled to a bilayer of a disordered superconductor and a magnetic insulator, motivated by recent experiments reporting possible Majorana-zero-mode…
