First and second quantized digital quantum simulations of bosonic systems
Mathias Mikkelsen, Hubert Okadome Valencia
We compare the basic resource requirements for first and second quantized bosonic mappings in a system consisting of particles in modes. In addition to the standard binary…
Entanglement-enhanced correlation propagation in the one-dimensional SU() Fermi-Hubbard model
Mathias Mikkelsen, Ippei Danshita
We investigate the dynamics of correlation propagation in the one-dimensional Fermi-Hubbard model with SU() symmetry when the repulsive-interaction strength is quenched from a l…
Quantum-selected configuration interaction with time-evolved state
Mathias Mikkelsen, Yuya O. Nakagawa
Quantum-selected configuration interaction (QSCI) utilizes an input quantum state on a quantum device to select important bases (electron configurations in quantum chemistry) that…
Static and dynamic phases of a Tonks-Girardeau gas in an optical lattice
Mathias Mikkelsen, Thomás Fogarty, Thomas Busch
We investigate the properties of a Tonks-Girardeau gas in the presence of a one-dimensional lattice potential. Such a system is known to exhibit a pinning transition when the latti…
