A quantum network of clocks
Peter Kómár, Eric M. Kessler, Michael Bishof +4
The development of precise atomic clocks has led to many scientific and technological advances that play an increasingly important role in modern society. Shared timing information…
Heisenberg-limited atom clocks based on entangled qubits
Eric M. Kessler, Peter Kómár, Michael Bishof +4
We present a quantum-enhanced atomic clock protocol based on groups of sequentially larger Greenberger-Horne-Zeilinger (GHZ) states, that achieves the best clock stability allowed…
A single photon transistor based on superconducting systems
Marco T. Manzoni, Florentin Reiter, Jacob Taylor +1
We present a realistic scheme for how to construct a single-photon transistor where the presence or absence of a single microwave photon controls the propagation of a subsequent st…
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…
Efficient atomic clocks operated with several atomic ensembles
Johannes Borregaard, Anders S. Sørensen
Atomic clocks are typically operated by locking a local oscillator (LO) to a single atomic ensemble. In this article we propose a scheme where the LO is locked to several atomic en…
Steady state entanglement of two superconducting qubits engineered by dissipation
Florentin Reiter, L. Tornberg, Göran Johansson +1
We present a scheme for the dissipative preparation of an entangled steady state of two superconducting qubits in a circuit QED setup. Combining resonator photon loss, a dissipativ…
