Ground state preparation of random all-to-all Hamiltonians using ADAPT-VQE
Sabhyata Gupta, Bharath Sambasivam, Sophia E. Economou +3
The ground state of random Hamiltonians with all-to-all interactions such as the quantum Sherrington-Kirkpatrick (SK) model and the Sachdev-Ye-Kitaev (SYK) model follow volume-law…

Exact stabilizer scars in two-dimensional lattice gauge theory
Sabhyata Gupta, Piotr Sierant, Luis Santos +1
The complexity of highly excited eigenstates is a central theme in nonequilibrium many-body physics, underpining questions of thermalization, classical simulability, and quantum in…

Fast generation of Pauli transfer matrices utilizing tensor product structure
Lukas Hantzko, Lennart Binkowski, Sabhyata Gupta
Analysis of quantum processes, especially in the context of noise, errors, and decoherence is essential for the improvement of quantum devices. An intuitive representation of those…
