Coherent rotations of qubits within a multi-species ion-trap quantum computer
Martin W. van Mourik, Esteban A. Martinez, Lukas Gerster +4
We describe, realize, and experimentally investigate a method to perform physical rotations of ion chains, trapped in a segmented surface Paul trap, as a building block for large s…
Characterizing large-scale quantum computers via cycle benchmarking
Alexander Erhard, Joel James Wallman, Lukas Postler +7
Quantum computers promise to solve certain problems more efficiently than their digital counterparts. A major challenge towards practically useful quantum computing is characterizi…
U(1) Wilson lattice gauge theories in digital quantum simulators
Christine Muschik, Markus Heyl, Esteban Martinez +7
Lattice gauge theories describe fundamental phenomena in nature, but calculating their real-time dynamics on classical computers is notoriously difficult. In a recent publication […
Real-time dynamics of lattice gauge theories with a few-qubit quantum computer
E. A. Martinez, C. A. Muschik, P. Schindler +8
Gauge theories are fundamental to our understanding of interactions between the elementary constituents of matter as mediated by gauge bosons. However, computing the real-time dyna…
Compiling quantum algorithms for architectures with multi-qubit gates
Esteban A. Martinez, Thomas Monz, Daniel Nigg +2
Quantum algorithms require a universal set of gates that can be implemented in a physical system. For these, an optimal decomposition into a sequence of available operations is des…
Realization of a scalable Shor algorithm
Thomas Monz, Daniel Nigg, Esteban A. Martinez +6
Quantum computers are able to outperform classical algorithms. This was long recognized by the visionary Richard Feynman who pointed out in the 1980s that quantum mechanical proble…
Experimental Quantum Computations on a Topologically Encoded Qubit
Daniel Nigg, Markus Mueller, Esteban A. Martinez +5
The construction of a quantum computer remains a fundamental scientific and technological challenge, in particular due to unavoidable noise. Quantum states and operations can be pr…
Measurement-based quantum computation with trapped ions
B. P. Lanyon, P. Jurcevic, M. Zwerger +6
Measurement-based quantum computation (MBQC) represents a powerful and flexible framework for quantum information processing, based on the notion of entangled quantum states as com…
A quantum information processor with trapped ions
Philipp Schindler, Daniel Nigg, Thomas Monz +10
Quantum computers hold the promise to solve certain problems exponentially faster than their classical counterparts. Trapped atomic ions are among the physical systems in which bui…
Quantum simulation of open-system dynamical maps with trapped ions
P. Schindler, M. Müller, D. Nigg +7
Dynamical maps describe general transformations of the state of a physical system, and their iteration can be interpreted as generating a discrete time evolution. Prime examples in…
Undoing a quantum measurement
Philipp Schindler, Thomas Monz, Daniel Nigg +6
In general, a quantum measurement yields an undetermined answer and alters the system to be consistent with the measurement result. This process maps multiple initial states into a…
Can different quantum state vectors correspond to the same physical state? An experimental test
Daniel Nigg, Thomas Monz, Philipp Schindler +7
A century on from the development of quantum theory, the interpretation of a quantum state is still discussed. If a physicist claims to have produced a system with a particular wav…
