David Edward Bruschi

In the past few years, advances in quantum thermodynamics have shown that work can be stored in the quantum correlations of a state. A thermal state is the most entropic state one can prepare given a fixed amount of energy. However, with the same amount of energy, one can prepare a state with some entanglement, which can be used in clever protocols to perform for, i.e., to "store energy".

If this is true, entanglement should have a weight, since we have known for more than a century that energy has a weight.

I have worked on answering a preliminary question, which could set a challenge and a direction of research [1]: understanding which type of entanglement weighs, and why.
