Autonomous Quantum Error Correction and Application to Quantum Sensing with Trapped Ions
F. Reiter, A. S. Sørensen, P. Zoller +1
Quantum-enhanced measurements hold the promise to improve high-precision sensing ranging from the definition of time standards to the determination of fundamental constants of natu…
High-fidelity dissipative engineering using parametric interactions
E. Doucet, F. Reiter, L. Ranzani +1
Established methods for dissipative state preparation typically rely on resolving resonances, limiting the target state fidelity due to competition between the stabilization mechan…
Dissipative preparation of entanglement in optical cavities
M. J. Kastoryano, F. Reiter, A. S. Sørensen
We propose a novel scheme for the preparation of a maximally entangled state of two atoms in an optical cavity. Starting from an arbitrary initial state, a singlet state is prepare…
Generation of a maximally entangled state using collective optical pumping
M. Malinowski, C. Zhang, V. Negnevitsky +7
We propose and implement a novel scheme for dissipatively pumping two qubits into a singlet Bell state. The method relies on a process of collective optical pumping to an excited l…
Nonunitary Gate Operations by Dissipation Engineering
E. Zapusek, A. Javadi, F. Reiter
Irreversible logic is at odds with unitary quantum evolution. Emulating such operations by classical measurements can result in disturbances and high resource demands. To overcome…
A phonon laser in the quantum regime
T. Behrle, T. L. Nguyen, F. Reiter +7
We demonstrate a trapped-ion system with two competing dissipation channels, implemented independently on two ion species co-trapped in a Paul trap. By controlling coherent spin-os…
Dissipative production of a maximally entangled steady state
Y. Lin, J. P. Gaebler, F. Reiter +5
Entangled states are a key resource in fundamental quantum physics, quantum cryp-tography, and quantum computation [1].To date, controlled unitary interactions applied to a quantum…
Preparation of entangled states through Hilbert space engineering
Y. Lin, J. P. Gaebler, F. Reiter +10
Entangled states are a crucial resource for quantum-based technologies such as quantum computers and quantum communication systems (1,2). Exploring new methods for entanglement gen…
