Quantum network of neutral atom clocks
P. Kómár, T. Topcu, E. M. Kessler +4
We propose a protocol for creating a fully entangled GHZ-type state of neutral atoms in spatially separated optical atomic clocks. In our scheme, local operations make use of the s…
Universal Quantum Transducers based on Surface Acoustic Waves
Martin J. A. Schuetz, Eric M. Kessler, Geza Giedke +3
We propose a universal, on-chip quantum transducer based on surface acoustic waves in piezo-active materials. Because of the intrinsic piezoelectric (and/or magnetostrictive) prope…
Long-distance entanglement distribution using individual atoms in optical cavities
Johannes Borregaard, Peter Kómár, Eric M. Kessler +2
Individual atoms in optical cavities can provide an efficient interface between stationary qubits and flying qubits (photons), which is an essentiel building block for quantum comm…
Nuclear Spin Dynamics in Double Quantum Dots: Multi-Stability, Dynamical Polarization, Criticality and Entanglement
Martin J. A. Schuetz, Eric M. Kessler, Lieven M. K. Vandersypen +2
We theoretically study the nuclear spin dynamics driven by electron transport and hyperfine interaction in an electrically-defined double quantum dot (DQD) in the Pauli-blockade re…
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…
Quantum Error Correction for Metrology
Eric M. Kessler, Igor Lovchinsky, Alexander O. Sushkov +1
We propose and analyze a new approach based on quantum error correction (QEC) to improve quantum metrology in the presence of noise. We identify the conditions under which QEC allo…
Superradiance-like Electron Transport through a Quantum Dot
Martin J. A. Schuetz, Eric M. Kessler, J. Ignacio Cirac +1
We theoretically show that intriguing features of coherent many-body physics can be observed in electron transport through a quantum dot (QD). We first derive a master equation bas…
Generalized Schrieffer-Wolff Formalism for Dissipative Systems
Eric M. Kessler
We present a formalized perturbation theory for Markovian open systems in the language of a generalized Schrieffer-Wolff (SW) transformation. A non-unitary rotation decouples the u…
Dissipative Phase Transition in Central Spin Systems
Eric M. Kessler, Geza Giedke, Atac Imamoglu +3
We investigate dissipative phase transitions in an open central spin system. In our model the central spin interacts coherently with the surrounding many-particle spin environment…
Nuclear spin cooling using Overhauser field selective coherent population trapping
Mena Issler, Eric Kessler, Geza Giedke +4
Hyperfine interactions with a nuclear spin environment fundamentally limit the coherence properties of confined electron spins in the solid-state. Here, we show that a quantum inte…
Optical Superradiance from Nuclear Spin Environment of Single Photon Emitters
E. M. Kessler, S. Yelin, M. D. Lukin +2
We show that superradiant optical emission can be observed from the polarized nuclear spin ensemble surrounding a single photon emitter such as a single quantum dot (QD) or Nitroge…
Light-mass Bragg cavity polaritons in planar quantum dot lattices
E. M. Kessler, M. Grochol, C. Piermarocchi
The exciton-polariton modes of a quantum dot lattice embedded in a planar optical cavity are theoretically investigated. Umklapp terms, in which an exciton interacts with many cavi…
