A symmetry-protected topological optical lattice clock
Tianrui Xu, Anjun Chu, Kyungtae Kim +4
We theoretically propose a tunable implementation of symmetry-protected topological phases in a synthetic superlattice, taking advantage of the long coherence time and exquisite sp…

Exploring the dynamical interplay between mass-energy equivalence, interactions and entanglement in an optical lattice clock
Anjun Chu, Victor J. MartÃnez-Lahuerta, Maya Miklos +5
We propose protocols that probe manifestations of the mass-energy equivalence in an optical lattice clock (OLC) interrogated with spin coherent and entangled quantum states. To tun…

Multi-qubit gates and Schrödinger cat states in an optical clock
Alec Cao, William J. Eckner, Theodor Lukin Yelin +8
Many-particle entanglement is a key resource for achieving the fundamental precision limits of a quantum sensor. Optical atomic clocks, the current state-of-the-art in frequency pr…
