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…
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…
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…
Parametric multi-element coupling architecture for coherent and dissipative control of superconducting qubits
G. B. P. Huber, F. A. Roy, L. Koch +20
As systems for quantum computing keep growing in size and number of qubits, challenges in scaling the control capabilities are becoming increasingly relevant. Efficient schemes to…
Sub-Harmonic Control of a Fluxonium Qubit via a Purcell-Protected Flux Line
Johannes Schirk, Florian Wallner, Longxiang Huang +21
Protecting qubits from environmental noise while maintaining strong coupling for fast high-fidelity control is a central challenge for quantum information processing. Here, we demo…
