## Engineering the speedup of quantum tunneling in Josephson systems via dissipation

It is common sense that when a quantum coherent system is not perfectly isolated from the environment, quantum effects are destroyed and the system fundamentally follows the classical mechanics’ rules. This is not always the case. Indeed, the dissipative interaction, namely the interaction between a quantum system and its external bath, can lead to an enhancement of quantum effects.

In this work we show that a such situation can occur in a superconducting Josephson circuit with an extremely…
