Butterfly Echo Protocol for Axis-Agnostic Heisenberg-Limited Metrology
Jacob Bringewatt, Leon Zaporski, Matthew Radzihovsky +4
The extreme sensitivity of chaotic systems to external perturbations makes them natural candidates for sensing applications. We propose a single-shot echo-based protocol for estima…
Quantum-amplified global-phase spectroscopy on an optical clock transition
Leon Zaporski, Qi Liu, Gustavo Velez +5
Optical lattice clocks (OLCs) are at the forefront of precision metrology, operating near a standard quantum limit (SQL) set by quantum noise. Harnessing quantum entanglement offer…
Many-body quantum register for a spin qubit
Martin Hayhurst Appel, Alexander Ghorbal, Noah Shofer +8
Quantum networks require quantum nodes with coherent optical interfaces and multiple stationary qubits. In terms of optical properties, semiconductor quantum dots are highly compel…
Tuning the coherent interaction of an electron qubit and a nuclear magnon
Noah Shofer, Leon Zaporski, Martin Hayhurst Appel +9
A central spin qubit interacting coherently with an ensemble of proximal spins can be used to engineer entangled collective states or a multi-qubit register. Making full use of thi…
