University of Illinois researchers demonstrate entanglement via energy leakage

Researchers from the University of Illinois Urbana-Champaign and the University of Chicago have demonstrated that energy leakage, typically viewed as a disadvantage, can be used to generate sustained quantum entanglement. Using a technique known as synthetic squeezing, the team successfully applied this phenomenon to superconducting qubits.

This method allows for the creation of entanglement in a steady state, bypassing the need to physically transport delicate quantum states. By utilizing continuous interaction and dissipation rather than vulnerable transport stages, this approach could provide a more reliable path for long-distance quantum communication and help address decoherence issues in quantum networks.
