Physicists have developed a new protocol that manipulates the arrow of time in quantum systems, using a measurement engine to extract energy from quantum systems. The researchers found that their tool made the evolution of these quantum systems more consistent with time flowing backward. The protocol is a mathematical framework to describe how monitored quantum systems evolve and allows them to manipulate the dynamics of these systems. This could potentially enhance the energy potential of technology like quantum batteries or algorithms in quantum devices. However, the researchers are currently working on a protocol to experimentally demonstrate its idea using superconducting qubits.
