Researchers Achieve Stable Quantum Entanglement with Dissipation Control

Scientists from the Research Laboratory of Electronics, in collaboration with Chalmers University of Technology, MIT, and Massachusetts Institute of Technology, have successfully demonstrated driven-dissipative entanglement between two giant artificial atoms coupled to a waveguide. This novel approach utilizes continuous-wave driving and correlated dissipation to generate and preserve remote entanglement, achieving a Bell-state fidelity of 0.89 ±0.02. This breakthrough offers a crucial pathway toward building practical quantum networks by overcoming limitations of traditional entanglement schemes.
