Universal decoherence due to gravitational time dilation
Igor Pikovski, Magdalena Zych, Fabio Costa +1
The physics of low-energy quantum systems is usually studied without explicit consideration of the background spacetime. Phenomena inherent to quantum theory on curved space-time,…
Dissipative transverse-field Ising model: steady-state correlations and spin squeezing
Tony E. Lee, Ching-Kit Chan
We study the transverse-field Ising model with infinite-range coupling and spontaneous emission on every site. We find that there is spin squeezing in steady state due to the prese…
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…
Enhanced index of refraction in four-wave mixing media
Elena Kuznetsova, Renuka Rajapakse, Susanne F. Yelin
Refractive index enhancement accompanied by vanishing absorption in a four-level atomic system interacting with two control and two probe fields in a regime of four-wave mixing (FW…
Preparation of Nuclear Spin Singlet States using Spin-Lock Induced Crossing
Stephen J. DeVience, Ronald L. Walsworth, Matthew S. Rosen
We introduce a broadly applicable technique to create nuclear spin singlet states in organic molecules and other many-atom systems. We employ a novel pulse sequence to produce a sp…
Certifying Separability in Symmetric Mixed States, and Superradiance
Elie Wolfe, S. F. Yelin
Separability criteria are typically of the necessary, but not sufficient, variety, in that satisfying some separability criterion, such as positivity of eigenvalues under partial t…
Quantum synchronization of quantum van der Pol oscillators with trapped ions
Tony E. Lee, H. R. Sadeghpour
Van der Pol oscillators are prototypical self-sustaining oscillators which have been used to model nonlinear processes in biological and other classical processes. In this work, we…
