Researchers Demonstrate Stable Quantum Entanglement With Dissipation Control

Aziza Almanakly and colleagues at Research Laboratory of Electronics, in collaboration with Chalmers University of Technology, MIT and Massachusetts Institute of Technology , have achieved driven-dissipative entanglement between two giant artificial atoms coupled to a waveguide. Their approach uses continuous-wave driving and correlated dissipation to generate and preserve remote entanglement, attaining a Bell-state fidelity of 0.89 ±0.02. The findings offer a key pathway towards building practical quantum networks by overcoming limitations associated with traditional entanglement schemes and demonstrating the viability of using driven dissipation in giant atom systems.
