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…
