Emergent Non-Markovian Nonlinear Qubit From Collective Spin Interactions
Gregory T. Carroll, Michael R. Geller, Andre Erpenbeck
Open-system descriptions are typically introduced by coupling a quantum system to an external environment. Here we show that a closed interacting many-body system can itself genera…

From spin squeezing to fast state discrimination
Michael R. Geller
There is great interest in generating and controlling entanglement in Bose-Einstein condensates and similar ensembles for use in quantum computation, simulation, and sensing. One c…

Quantum simulation of a qubit with non-Hermitian Hamiltonian
Anastashia Jebraeilli, Michael R. Geller
Modeling non-Hermitian Hamiltonians is increasingly important in classical and quantum domains, especially when studying open systems, symmetry, and resonances. However, the q…
