Simply

By connecting special giant atoms to a shared wire, researchers can use a constant signal to force the atoms into a shared, protected state, creating stable entanglement across a distance.

In depth

The authors propose a method to generate remote entanglement between giant artificial atoms by exploiting correlated dissipation in a waveguide-quantum electrodynamics (wQED) architecture. By engineering the interference between multiple coupling points of each atom, they create a system where a continuous drive stabilizes a protected dark state, which is then isolated from waveguide decay by tuning the qubit frequencies to a subradiant point.

Key Takeaways

1
The paper demonstrates the use of giant atoms to enable tunable, frequency-dependent dissipation in a waveguide.
2
A single continuous-wave drive is sufficient to stabilize a Bell state through driven-dissipative dynamics.
3
The authors achieve a Bell-state fidelity of $F = 0.89 \pm 0.02$ by suppressing individual dissipation after entanglement generation.

Results

The atoms stay entangled even when the drive is turned off because they are tuned to a protected frequency.
