Fast Native Three-Qubit Gates and Fault-Tolerant Quantum Error Correction with Trapped Rydberg Ions
Katrin Bolsmann, Thiago L. M. Guedes, Weibin Li +3
Trapped ions as one of the most promising quantum-information-processing platforms, yet conventional entangling gates mediated by collective motion remain slow and difficult to sca…
Two-qubit gate protocols with microwave-dressed Rydberg ions in a linear Paul trap
Joseph W. P. Wilkinson, Katrin Bolsmann, Thiago L. M. Guedes +2
Ultracold trapped atomic ions excited into highly energetic Rydberg states constitute a promising platform for scalable quantum information processing. Elementary building blocks f…
Taming Thiemann's Hamiltonian constraint in canonical loop quantum gravity: reversibility, eigenstates and graph-change analysis
Thiago L. M. Guedes, Guillermo A. Mena Marugán, Markus Müller +1
The Hamiltonian constraint remains an elusive object in loop quantum gravity because its action on spinnetworks leads to changes in their corresponding graphs. As a result, calcula…
Computing the graph-changing dynamics of loop quantum gravity
Thiago L. M. Guedes, Guillermo A. Mena Marugán, Francesca Vidotto +1
In loop quantum gravity (LQG), states of the gravitational field are represented by labeled graphs called spin networks. Their dynamics can be described by a Hamiltonian constraint…
