QSLTHERMO19: Quantum Speed Limits and Thermodynamics

The international meeting "Quantum Speed limits and Thermodynamics" (QSLTHERMO2019) aims at gathering world-wide leading experts on quantum science and technology working at the interface of quantum control, far-from-equilibrium physics, and quantum information science. Quantum speed limits are a set of fundamental results in information geometry that provide bounds on the rate at which physical processes can occur, the limits of computational power of physical devices, and the performance of quantum machines. The engineering of energy-efficient thermal machines and the optimization of quantum processes such as information processing are at the forefront of quantum thermodynamics, which gives the thermodynamics of small quantum systems. The interplay of these two topics is currently a fast-paced area of research and the focus of the meeting.

Quantum Simulation

During the last years, a synergy among different fields in physics has grown up to understand and characterize, to control and manipulate quantum many-body systems that appear in high-energy physics and condensed matter models. Thanks to this collaborative effort, new tools and concepts from quantum information and quantum optics complement more traditional ones from particle and statistical physics.

The purpose of this workshop is to bring together in a three days meeting, experts and leaders in the field to present and discuss the most recent results and outlook the most promising directions of this multidisciplinary challenge.

Scope

Tailoring the far from equilibrium dynamics of quantum matter is an open problem at the frontiers of physics. Yet, it is also a necessity for the development of quantum science and technology. Conventional adiabatic protocols are ubiquitously exploited for the manipulation and control of quantum matter in a wide variety of fields. They require however long evolution times and are thus prone to noise and decoherence errors.

Shortcuts to adiabaticity provide an alternative control paradigm, free from the requirement of slow driving. They have been exploited in various quantum platforms with both discrete and continuous variables. Prominent examples include ultracold gases, trapped ions, nitrogen-vacancy centers and other realizations of few-level systems. Shortcuts to adiabaticity have also important implications on the foundations and applications of quantum theory, quantum statistical mechanics and thermodynamics, quantum optics, quantum control, quantum information processing and quantum computation.

This special issue aims at spurring the development of shortcuts to adiabaticity, fostering experimental and theoretical progress at the frontiers of the field.

Scope

In Edwin Abbott's iconic "Flatland" the two-dimensional protagonist, after having been visited by the three-dimensional creatures, infers that life in an imaginary—within the novel—one-dimensional Lineland would show several very peculiar counterintuitive features. The Lineland of the many-body physics follows the same plot. Quantum exchange statistics and interactions there are inextricably intertwined and thus inseparable. Particle order becomes a topological concept. Finally, the one-dimensional particles are one step away from multidimensional billiards, kaleidoscopes in particular. These properties opened a door to a zoo of solvable many-body models, discovered in the early 60s and still half explored.

In the new millennium, the one-dimensional models found another application. Tightly-confined ultracold gases are being investigated as a platform for quantum technologies, from quantum metrology to universal quantum computation.

This special issue aims at spurring further advances in the understanding and exploiting the "beautiful" solvable many-body models and commemorating the seminal contributions to the field by Marvin D Girardeau (1930–2015), whose 1960 solution for the quantum hard-core boson model started it all.

Thermodynamics and Nonlinear Dynamics in the Information Age (TSRC, Telluride, CO)

Meeting Description:

Since its beginnings one of the main purposes of thermodynamics has been the optimization of devices. Commonly, processes are characterized as optimal if they are maximally fast or maximally efficient. Recent years have seen the development of various theoretical tools which tremendously broadened our understanding of such optimal processes, in quantum mechanics and in classical physics. A particular highlight are so-called shortcuts to adiabaticity -- finite time processes that mimic adiabatic dynamics without the requirement of slow driving. These exciting new results found relevance and application in a wide variety of fields including Quantum Sensing and Metrology, Finite-Time Thermodynamics, Quantum Simulation, Quantum Computation, Quantum Communication, and Quantum Optimal Control Theory. A second pillar of modern thermodynamic optimization are so-called information engines. In these systems the effects of information gain and its feedback into the dynamics are explicitly studied. As a consequence Maxwell demon-like systems have lost its demonic obscurity and have become an integral part of realistic optimization. All of these processes are frequently governed by inherently nonlinear equations. This conference aims at an exchange of ideas from researchers in Non-Equilibrium Thermodynamics, Atomic, Molecular, and Optical Sciences, Quantum Information and Quantum Technologies, Statistical Mechanics, Optimal Control Theory, and Nonlinear Dynamics.

Meeting Description:

The adiabatic theorem seems to be a no-go theorem for excitation-free ultrafast processes in quantum dynamics of relevance to a great variety of fields and technologies including quantum sensing and metrology, finite-time thermodynamics, quantum simulation, and quantum computation. However, it is possible to design non-adiabatic processes that reproduce in a finite-time the same final state resulting from an adiabatic protocol. Examples of architectures where these ideas can be applied include neutral atoms and Bose-Einstein condensates, spin systems, quantum dots, and trapped ions, among others. The growing body of theoretical and experimental research in this area, spanning a range of topics including quantum control, classical dynamics, and small-system thermodynamics, is consolidating shortcuts to adiabaticity as an emergent field. This workshop is aimed at bringing together experts in non-equilibrium dynamics across different communities, encompassing Atomic, Molecular and Optical Sciences, Quantum information and Quantum Technologies, and Statistical mechanics.
