• Abstract: Shortcut to isothermality is a driving strategy to steer the system to its equilibrium states within finite time, and enables evaluating the impact of a control promptly. Finding optimal scheme to minimize the energy cost is of critical importance in applications of this strategy in pharmaceutical drug test, biological selection, and quantum computation. We prove the equivalence between designing the optimal scheme and finding the geodesic path in the space of control parameters. Such equivalence allows a systematic and universal approach to find the optimal control to reduce the energy cost. We demonstrate the current method with examples of a Brownian particle trapped in controllable harmonic potentials.

  We implement Landauer erasure on a driven electron level in a semiconductor quantum dot. We compare the standard protocol in which the energy is increased linearly in time with the one coming from geometric optimisation. We show experimentally that geodesic drivings minimise dissipation for slow protocols, with a bigger improvement as one approaches perfect erasure.

  Adiabatic protocols are employed across a variety of quantum technologies. The problem of speeding up these processes has garnered a large amount of interest. Two approaches are complementary: optimal control manipulates control fields to steer the dynamics. shortcuts to adiabaticity aim to retain the adiabatic condition upon speed-up.

• Optimizing thermalizations [0.0]
  We present a rigorous approach, based on the concept of continuous thermomajorisation, to algorithmically characterise the full set of energy occupations of a quantum system. We illustrate this by finding optimal protocols in the context of cooling, work extraction and optimal sequences. The same tools also allow one to quantitatively assess the role played by memory effects in the performance of thermodynamic protocols.

• Targeted free energy estimation via learned mappings [66.20146549150475]
  Free energy perturbation (FEP) was proposed by Zwanzig more than six decades ago as a method to estimate free energy differences. FEP suffers from a severe limitation: the requirement of sufficient overlap between distributions. One strategy to mitigate this problem, called Targeted Free Energy Perturbation, uses a high-dimensional mapping in configuration space to increase overlap.
