High-performance cellular automaton decoders for quantum repetition and toric code

Don Winter, Thiago L. M. Guedes, Markus Müller

Execution of quantum algorithms on large-scale quantum computers will require extremely low logical error rates, which necessitates the development of scalable decoding architectur…

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…

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…

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…

Quantum cellular automata for quantum error correction and density classification

Thiago L. M. Guedes, Don Winter, Markus Müller

Quantum cellular automata are alternative quantum-computing paradigms to quantum Turing machines and quantum circuits. Their working mechanisms are inherently automated, therefore…

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…
