Physicists reveal a measurement-based feedback protocol that can steer a monitored quantum system’s evolution to mimic reversed time, effectively reshaping the arrow of time and enabling potential energy extraction in quantum devices; while not time travel, the approach could boost quantum batteries and algorithms, with plans to test on superconducting qubits.
Researchers from the Okinawa Institute of Science and Technology, in collaboration with German universities, have developed a quantum engine powered by quantum entanglement, rather than traditional combustion or heat. This engine operates by cyclically converting fermions into bosons and vice versa, utilizing the energy difference between these states. While the engine's efficiency can reach up to 25% in controlled lab conditions, practical applications remain distant due to the delicate and cold conditions required for operation. This innovation highlights the potential of quantum mechanics to revolutionize energy extraction methods.
Researchers have developed a quantum engine using entangled calcium ions, demonstrating that entanglement can boost the useful energy produced by the engine, though not its energy conversion efficiency. This breakthrough, published in Physical Review Letters, marks the first experimental realization of a quantum engine with entangled characteristics, potentially paving the way for more efficient quantum devices operating at extremely low temperatures.
Chinese researchers have developed the first quantum engine powered by quantum entanglement, demonstrating enhanced energy efficiency and potential for future quantum technologies. The study, published in Physical Review Letters, shows that entanglement can serve as a type of "fuel," potentially revolutionizing energy conversion and powering large-scale quantum computers and circuits.
