Entanglement-enhanced optical ion clock
Kai Dietze, Lennart Pelzer, Ludwig Krinner +11
Entangled states hold the promise of improving the precision and accuracy of quantum sensors. We experimentally demonstrate that spectroscopy of an optical clock transition using e…
Arbitrary quantum circuits on a fully integrated two-qubit computation register for a trapped-ion quantum processor
N. Pulido-Mateo, H. Mendpara, M. Duwe +4
We report on the implementation of arbitrary circuits on a universal two-qubit register that can act as the computational module in a trapped-ion quantum computer based on the quan…
Multi-ion frequency reference using dynamical decoupling
Lennart Pelzer, Kai Dietze, Víctor J. Martínez-Lahuerta +6
We present the experimental realization of a continuous dynamical decoupling scheme which suppresses leading frequency shifts in a multi-ion frequency reference based on $^{40}\mat…
Coherent photo-thermal noise cancellation in a dual-wavelength optical cavity for narrow-linewidth laser frequency stabilisation
Fabian Dawel, Alexander Wilzewski, Sofia Herbers +7
Optical resonators are used for the realisation of ultra-stable frequency lasers. The use of high reflectivity multi-band coatings allows the frequency locking of several lasers of…
A low phase noise cavity transmission self-injection locked laser system for atomic physics experiments
Ludwig Krinner, Kai Dietze, Lennart Pelzer +2
Lasers with high spectral purity are indispensable for optical clocks and coherent manipulation of atomic and molecular qubits for applications such as quantum computing and quantu…
Quadrupole transitions and quantum gates protected by continuous dynamic decoupling
V. J. Martínez-Lahuerta, L. Pelzer, K. Dietze +3
Dynamical decoupling techniques are a versatile tool for engineering quantum states with tailored properties. In trapped ions, nested layers of continuous dynamical decoupling by m…
Numerical optimization of amplitude-modulated pulses in microwave-driven entanglement generation
M. Duwe, G. Zarantonello, N. Pulido-Mateo +7
Microwave control of trapped ions can provide an implementation of high-fidelity two-qubit gates free from errors induced by photon scattering. Furthermore, microwave conductors ma…
