  • Irreversible computation cannot be performed without a work cost, and energy dissipation imposes limitations on devices' performances. Here the authors show that the minimal work requirement of logical operations is given by the amount of discarded information, measured by entropy.

  • By exploiting the electro-optic properties of thin-film lithium niobate, an integrated single-waveguide Fourier transform spectrometer with a footprint of <10 mm2 and an operational bandwidth of 500 nm in the near- and short-wavelength infrared is demonstrated.

  • A central concept in thermodynamics is the thermal state, which is the one towards which the system relaxes. Here, the authors derive the same state, through three different approaches, in the case of a quantum system whose conserved quantities correspond to operators that do not commute with one another.

  • The dynamics of quantum states underlies the emergence of thermodynamics and even recent theories of quantum gravity. Now it has been proven that the quantum complexity of states evolving under random operations grows linearly in time.
