Error-corrected function estimation advantage in multiparameter Hamiltonians
Erfan Abbasgholinejad, Lorcán O. Conlon, Sean R. Muleady +4
We establish the ultimate precision limits for estimating a function of multiple Hamiltonian parameters in the presence of Markovian noise. By reducing multiparameter function esti…
Anomalous Boundary Modes in a Floquet Hyperbolic System
Ali Fahimniya, Hossein Dehghani, Alicia J. Kollár +1
We construct an anomalous Floquet topological phase on a negatively curved hyperbolic lattice. The model is a tight-binding Hamiltonian with a periodically repeated four-color edge…
Multimode Strong-Coupling Processes in Circuit QED Lattices
Won Chan Lee, Ali Fahimniya, Kellen O'Brien +5
Circuit QED systems provide an ideal platform for exploring the strong-coupling regime of multimode cavity QED. Here we present two new phenomena from multimode strong coupling: a…
In-situ Characterization of Light-Matter Coupling in Multimode Circuit-QED Systems
Kellen O'Brien, Won Chan Lee, Alexandra Behne +5
Multimode cavity-QED systems can be leveraged to explore a wide range of physical phenomena; however, a complex multimode environment makes systematic characterization of light-mat…
Low-depth fermion routing without ancillas
Nathan Constantinides, Jeffery Yu, Dhruv Devulapalli +6
Routing is the task of permuting qubits in such a way that quantum operations can be parallelized maximally, given constraints on the hardware geometry. When simulating fermions in…
Optimally learning functions in interacting quantum sensor networks
Erfan Abbasgholinejad, Sean R. Muleady, Jacob Bringewatt +4
Estimating extensive combinations of local parameters in distributed quantum systems is a central problem in quantum sensing, with applications ranging from magnetometry to timekee…
