“…Nearly 200 years later, the field of stochastic thermodynamics [2,3] similarly studies the design principles governing the ability to dynamically vary control parameters and perform work at minimum energetic cost (minimum dissipation), but now in micro-and nano-scale fluctuating systems. Minimum-dissipation protocols inform our understanding of the design principles of biological molecular machines [4,5] and are of practical use to single-molecule experiments [6], free-energy estimation [7][8][9][10][11], and thermodynamic computing [12,13].…”

“…The STEP can thus be computed relatively inexpensively, easing determination of minimum-dissipation protocols in rapidly driven complex chemical and biological systems. This opens the door to improve the energetic efficiency in thermodynamic computing [12,13] and the accuracy of nonequilibrium freeenergy estimates in simulations and single-molecule experiments [6,7,20,21].…”

Micro-and nano-scale systems driven by rapid changes in control parameters (control protocols) dissipate significant energy. In the fast-protocol limit, we find that protocols that minimize dissipation at fixed duration are universally given by a two-step process, jumping to and from a point that balances jump size with fast relaxation. Jump protocols could be exploited by molecular machines or thermodynamic computing to improve energetic efficiency, and implemented in nonequilibrium free-energy estimation to improve accuracy.

“…In the long run, the insight provided not only by the dissipative adaptation perspective but also by more general biologically inspired non-equilibrium self-organization could open radically new paths for classical and quantum information processing, which could potentially be useful for their resilience, self-restoring capacities, and exquisite thermodynamic efficiencies. In the classical case, we see promising discussions of alternative computational schemes with stochastic and biologically inspired systems in [32][33][34][35], for instance. In the quantum case, we would like to go beyond our discussions here and in [14,16] (concerned, respectively, with quantum cloning and heat management) so as to highlight the remarkable biologically inspired model for quantum error correction in [36] while also employing non-equilibrium light-matter interactions.…”

Quantum Dissipative Adaptation with Cascaded Photons

Classical dissipative adaptation is a hypothetical non-equilibrium thermodynamic principle of self-organization in driven matter, and it relates transition probabilities with the non-equilibrium work performed by an external drive on dissipative matter. Recently, the dissipative adaptation hypothesis was extended to a quantum regime with a theoretical model where only one single-photon pulse drives each atom of an ensemble. Here, we further generalize that quantum model by analytically showing that N cascaded single-photon pulses driving each atom still fulfill a quantum dissipative adaptation. Interestingly, we find that the level of self-organization achieved with two pulses can be matched with a single effective pulse only up to a threshold, above which the presence of more photons provides unparalleled degrees of self-organization.

“…In a very recent experiment, Saira et al [85] applied related techniques to thermal-fluctuation-driven logical bit reset on a superconducting flux logic cell. Such experiments are essential steps towards thermodynamic computing [86], which is a promising paradigm (and complementary to quantum computing) to overcome the restrictions imposed by the end of Moores law.…”
