On the power of moving quantum sensors: fully flexible and noise-resilient sensing
Paul Aigner, Wolfgang Dür
We show that a single moving quantum sensor provides complete access to spatially correlated scalar fields. We demonstrate that with either trajectory or internal state control, on…
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…
Qudit Noisy Stabilizer Formalism
Paul Aigner, Maria Flors Mor-Ruiz, Wolfgang Dür
We introduce the qudit Noisy Stabilizer Formalism, a framework for efficiently describing the evolution of stabilizer states in prime-power dimensions subject to generalized Pauli-…
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…
