svPITE: A Python package for the state-vector-based probabilistic imaginary-time evolution algorithm
Pascal Sievers, Satoshi Ejima
We present a Python package for ground-state preparation based on the probabilistic imaginary-time evolution algorithm, with particular focus on its state-vector-based implementati…

Probabilistic imaginary-time evolution in state-vector-based and shot-based simulations and on quantum devices
Satoshi Ejima, Kazuhiro Seki, Benedikt Fauseweh +1
Imaginary-time evolution, an important technique in tensor network and quantum Monte Carlo algorithms on classical computers, has recently been adapted to quantum computing. In thi…

Radiative Higgs mode in photoinduced pairs
Satoshi Ejima, Benedikt Fauseweh
We demonstrate that the symmetry of the pump-induced -pairing state in the Hubbard chain can be transiently broken by an additionally applied probe pulse. This leads to ch…
