Modular fault-tolerant quantum computing on a non-CSS code
Robert Freund, Friederike Butt, César Benito +6
Modularization promises to break down the design and implementation complexity of large scale quantum processors into smaller manageable subtasks. In this approach, quantum channel…
Complementary 3D color codes for transversal quantum logic
Friederike Butt, Luis Colmenarez, Erik Weilandt +3
Transversal logical gates provide a direct route to fault-tolerant quantum computation, but the Eastin-Knill theorem forbids a universal transversal gate set within a single quantu…
Decoding 3D color codes with boundaries
Friederike Butt, Lars Esser, Markus Müller
Practical large-scale quantum computation requires both efficient error correction and robust implementation of logical operations. Three-dimensional (3D) color codes are a promisi…
Demonstration of measurement-free universal fault-tolerant quantum computation
Friederike Butt, Ivan Pogorelov, Robert Freund +4
The ability to perform quantum error correction (QEC) and robust gate operations on encoded qubits opens the door to demonstrations of quantum algorithms. Contemporary QEC schemes…
Measurement-free quantum error correction optimized for biased noise
Katharina Brechtelsbauer, Friederike Butt, David F. Locher +4
In this paper, we derive optimized measurement-free protocols for quantum error correction and the implementation of a universal gate set optimized for an error model that is noise…
Demonstration of High-Fidelity Entangled Logical Qubits using Transmons
Arian Vezvaee, Vinay Tripathi, Mario Morford-Oberst +3
Quantum error correction (QEC) codes are necessary to fault-tolerantly operate quantum computers. However, every such code is inherently limited by its inability to detect logical…
Measurement-free, scalable and fault-tolerant universal quantum computing
Friederike Butt, David F. Locher, Katharina Brechtelsbauer +2
Reliable execution of large-scale quantum algorithms requires robust underlying operations and this challenge is addressed by quantum error correction (QEC). Most modern QEC protoc…
Demonstration of two-dimensional connectivity for a scalable error-corrected ion-trap quantum processor architecture
Marco Valentini, Martin W. van Mourik, Friederike Butt +12
A major hurdle for building a large-scale quantum computer is increasing the number of qubits while maintaining connectivity between them. In trapped-ion devices, this connectivity…
Experimental fault-tolerant code switching
Ivan Pogorelov, Friederike Butt, Lukas Postler +4
Quantum error correction is a crucial tool for mitigating hardware errors in quantum computers by encoding logical information into multiple physical qubits. However, no single err…
Demonstration of fault-tolerant Steane quantum error correction
Lukas Postler, Friederike Butt, Ivan Pogorelov +7
Encoding information redundantly using quantum error-correcting (QEC) codes allows one to overcome the inherent sensitivity to noise in quantum computers to ultimately achieve larg…
Fault-Tolerant Code Switching Protocols for Near-Term Quantum Processors
Friederike Butt, Sascha Heußen, Manuel Rispler +1
Topological color codes are widely acknowledged as promising candidates for fault-tolerant quantum computing. Neither a two-dimensional nor a three-dimensional topology, however, c…
Flopping-mode electron dipole spin resonance in the strong-driving regime
Julian D. Teske, Friederike Butt, Pascal Cerfontaine +2
Achieving high fidelity control of spin qubits with conventional electron dipole spin resonance (EDSR) requires large magnetic field gradients of about 1 mT/nm, which also couple t…
