Multiqubit Rydberg Gates for Quantum Error Correction
David F. Locher, Josias Old, Katharina Brechtelsbauer +4
Multiqubit gates that involve three or more qubits are usually thought to be of little significance for fault-tolerant quantum error correction because single gate faults can lead…
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…
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…
Bosonic Quantum Error Correction with Neutral Atoms in Optical Dipole Traps
Leon H. Bohnmann, David F. Locher, Johannes Zeiher +1
Bosonic quantum error correction codes encode logical qubits in the Hilbert space of one or multiple harmonic oscillators. A prominent class of bosonic codes is that of Gottesman-K…
Weak pinning and long-range anticorrelated motion of phase boundaries in driven diffusive systems
Sören Schweers, David F. Locher, Gunter M. Schütz +1
We show that domain walls separating coexisting extremal current phases in driven diffusive systems exhibit complex stochastic dynamics, with a subdiffusive temporal growth of posi…
Computational Capabilities and Compiler Development for Neutral Atom Quantum Processors: Connecting Tool Developers and Hardware Experts
Ludwig Schmid, David F. Locher, Manuel Rispler +4
Neutral Atom Quantum Computing (NAQC) emerges as a promising hardware platform primarily due to its long coherence times and scalability. Additionally, NAQC offers computational ad…
Noise-aware variational eigensolvers: a dissipative route for lattice gauge theories
Jesús Cobos, David F. Locher, Alejandro Bermudez +2
We propose a novel variational ansatz for the ground-state preparation of the lattice gauge theory (LGT) in quantum simulators. It combines dissipative and unitary o…
Measurement-free fault-tolerant quantum error correction in near-term devices
Sascha Heußen, David F. Locher, Markus Müller
Logical qubits can be protected from decoherence by performing QEC cycles repeatedly. Algorithms for fault-tolerant QEC must be compiled to the specific hardware platform under con…
Quantum Error Correction with Quantum Autoencoders
David F. Locher, Lorenzo Cardarelli, Markus Müller
Active quantum error correction is a central ingredient to achieve robust quantum processors. In this paper we investigate the potential of quantum machine learning for quantum err…
