What is it about?
This work explores how a tiny quantum system, called a qubit, interacts with its environment (a "reservoir"), which is important for future technologies like quantum computers. The researchers found a way to measure how much information is shared between the qubit and its environment. Their experiment shows that as this interaction gets stronger, more information can be exchanged.

Why is it important?
What makes this work unique and timely is its focus on understanding how qubits, the building blocks of quantum computers, interact with their environment in ways that weren't fully explored before. By introducing a new way to measure these interactions, it paves the way for improving quantum technologies, like quantum computing and sensing, making them more reliable and efficient for future applications.
