Extending the fundamental limit of atomic clock stability
Ravid Shaniv, Ayush Agrawal, David B. Hume
Optical atomic clocks have been rapidly developing in recent decades, resulting in major improvements in both precision and accuracy. As a result, they have become instrumental in…
High Stability Mechanical Frequency Sensing beyond the Linear Regime
Sofia C. Brown, Ravid Shaniv, Ruomu Zhang +2
Sensing via a mechanical frequency shift is a powerful measurement tool, and, therefore, understanding and mitigating frequency noise affecting mechanical resonators is imperative.…
Direct Measurement of A Spatially Varying Thermal Bath Using Brownian Motion
Ravid Shaniv, Chris Reetz, Cindy A. Regal
Micro-mechanical resonator performance is fundamentally limited by the coupling to a thermal environment. The magnitude of this thermodynamical effect is typically considered in ac…
Understanding the Quality Factor of Mass-Loaded Tensioned Resonators
Ravid Shaniv, Sanjay Kumar Keshava, Chris Reetz +1
Mechanical resonators featuring large tensile stress have enabled a range of experiments in quantum optomechanics and novel sensing. Many sensing applications require functionalizi…
Theory of robust multi-qubit non-adiabatic gates for trapped-ions
Yotam Shapira, Ravid Shaniv, Tom Manovitz +5
The prevalent approach to executing quantum algorithms on quantum computers is to break-down the algorithms to a concatenation of universal gates, typically single and two-qubit ga…
Precision measurement of atomic isotope shifts using a two-isotope entangled state
Tom Manovitz, Ravid Shaniv, Yotam Shapira +2
Atomic isotope shifts (ISs) are the isotope-dependent energy differences in the atomic electron energy levels. These shifts serve an important role in atomic and nuclear physics, a…
Constraining Rapidly Oscillating Scalar Dark Matter Using Dynamic Decoupling
Shahaf Aharony, Nitzan Akerman, Roee Ozeri +3
We propose and experimentally demonstrate a method for detection of light scalar Dark Matter (DM), through probing temporal oscillations of fundamental constants in an atomic optic…
Quadrupole shift cancellation using dynamic decoupling
Ravid Shaniv, Nitzan Akerman, Tom Manovitz +2
We present a method that uses radio-frequency pulses to cancel the quadrupole shift in optical clock transitions. Quadrupole shifts are an inherent inhomogeneous broadening mechani…
Robust entanglement gates for trapped-ion qubits
Yotam Shapira, Ravid Shaniv, Tom Manovitz +2
High-fidelity two-qubit entangling gates play an important role in many quantum information processing tasks and are a necessary building block for constructing a universal quantum…
New ideas for tests of Lorentz invariance with atomic systems
Ravid Shaniv, Roee Ozeri, Marianna S. Safronova +4
We describe a broadly applicable experimental proposal to search for the violation of local Lorentz invariance (LLI) with atomic systems. The new scheme uses dynamic decoupling and…
Heisenberg-limited Rabi spectroscopy
Ravid Shaniv, Tom Manovitz, Yotam Shapira +2
The use of entangled states was shown to improve the fundamental limits of spectroscopy to beyond the standard-quantum limit. In these Heisenberg-limited protocols the phase betwee…
Fast dynamical decoupling of the Molmer-Sorensen entangling gate
Tom Manovitz, Amit Rotem, Ravid Shaniv +5
Engineering entanglement between quantum systems often involves coupling through a bosonic mediator, which should be disentangled from the systems at the operation's end. The quali…
Quantum Lock-in Force Sensing using Optical Clock Doppler Velocimetry
Ravid Shaniv, Roee Ozeri
Force sensors are at the heart of different technologies such as atomic force microscopy or inertial sensing \cite{RMPforce2003, Rugar2004, YazdiIEEE}. These sensors often rely on…
Atomic Quadrupole Moment Measurement Using Dynamic Decoupling
Ravid Shaniv, Nitzan Akerman, Roee Ozeri
We present a method that uses dynamic decoupling of a multi-level quantum probe to distinguish small frequency shifts that depend on , where is the angular momen…
