High-Fidelity Entangled States in a Connectivity-Four Fluxonium Quantum Processor
J. Schirk, N. Bruckmoser, S. M. Taubenberger +10
A central challenge in fluxonium-based quantum processors is the extension of the qubit connectivity to two-dimensional lattices compatible with quantum code-error correction. Here…
Implementing Hamiltonian Renormalization Group Flow on Quantum Computers with VAPOR
Federica Fragomeno, Jorden Roberts, Saeed Rastgoo +1
While Hamiltonian Lattice Gauge Theory is gaining traction, today's limited numerical capacity leaves simulations affected by discretization errors. This motivates the implementati…
Enhancing Variational Quantum Eigensolvers for SU(2) Lattice Gauge Theory via Systematic State Preparation
Klaus Liegener, Dominik Mattern, Alexander Korobov +7
Computing the vacuum and energy spectrum in non-Abelian, interacting lattice gauge theories remains an open challenge, in part because approximating the continuum limit requires la…
Spherically Symmetric Gravity on a Graph I: Theoretical Foundations
Klaus Liegener, Saeed Rastgoo, Jorden Roberts
This manuscript is the first in a series of instalments that investigate spherically symmetric solutions within the effective dynamics program of Loop Quantum Gravity. The choice o…
Theory of Multi-photon Processes for Applications in Quantum Control
Longxiang Huang, Jacquelin Luneau, Johannes Schirk +5
We present a general theoretical framework for evaluating multi-photon processes in periodically driven quantum systems, which have been identified as a versatile tool for engineer…
Scalable Fluxonium-Transmon Architecture for Error Corrected Quantum Processors
Lukas Heunisch, Longxiang Huang, Stephan Tasler +9
We propose a hybrid quantum computing architecture composed of alternating fluxonium and transmon qubits, that are coupled via transmon tunable couplers. We show that this system o…
