Improved Quantum Sensing by Spectral Design
Paul Aigner, Wolfgang Dür
We investigate how unitary control can improve parameter estimation by designing the effective spectrum of the imprinting Hamiltonian. We show that, for commuting Hamiltonians, the…
Long-ranged gates in quantum computation architectures with limited connectivity
Wolfgang Dür
We propose a quantum computation architecture based on geometries with nearest-neighbor interactions, including e.g. planar structures. We show how to efficiently split the role of…
Measurement-based quantum computing with qudit stabilizer states
Alena Romanova, Wolfgang Dür
We show how to perform measurement-based quantum computing on qudits (high-dimensional quantum systems) using alternative resource states beyond the cluster state. Estimating overh…
Selective and noise-resilient wave estimation with quantum sensor networks
Arne Hamann, Paul Aigner, Pavel Sekatski +1
We consider the selective sensing of planar waves in the presence of noise. We present different methods to control the sensitivity of a quantum sensor network, which allow one to…
Scalable repeater architectures for multi-party states
V. V. Kuzmin, D. V. Vasilyev, N. Sangouard +2
The vision to develop quantum networks entails multi-user applications, which require the generation of long-distance multi-party entangled states. The current rapid experimental p…
All macroscopic quantum states are fragile and hard to prepare
Andrea López-Incera, Pavel Sekatski, Wolfgang Dür
We study the effect of local decoherence on arbitrary quantum states. Adapting techniques developed in quantum metrology, we show that the action of generic local noise processes -…
