Quantum information can be encoded in the set of steady-states (SSS) of a driven-dissipative system. Non steady-states are separated by a large dissipative gap that adiabatically decouples them way while the dynamics inside the SSS is governed by an effective, dissipation-projected, Hamiltonian. The latter results from a highly non-trivial interplay between a weak driving with the fast relaxation process that continuously projects the system back to the SSS. This amounts to a novel type of…

Dynamical response theory for driven-dissipative quantum systems
We discuss dynamical response theory of driven-dissipative quantum systems described by Markovian master equations generating semigroups of maps. In this setting thermal equilibrium states are
Dissipative self-interference and robustness of continuous error-correction to miscalibration
We derive an effective equation of motion within the steady-state subspace of a large family of Markovian open systems (i.e., Lindbladians) due to perturbations of their Hamiltonians and
Dissipative universal Lindbladian simulation
It is by now well understood that quantum dissipative processes can be harnessed and turned into a resource for quantum-information processing tasks. In this paper we demonstrate yet another way in
Emerging unitary evolutions in dissipatively coupled systems
Having a broad range of methods available for implementing unitary operations is crucial for quantum information tasks. We study a dissipative process commonly used to describe dissipatively coupled
Targeting pure quantum states by strong noncommutative dissipation
We propose a solution to the problem of realizing a predefined and arbitrary pure quantum state, based on the simultaneous presence of coherent and dissipative dynamics, noncommuting on the target
Dynamical fidelity susceptibility of decoherence-free subspaces
textabstractIn idealized models of a quantum register and its environment, quantum information can be stored indefinitely by encoding it into a decoherence-free subspace (DFS). Nevertheless,
Demonstrating robust simulation of driven-dissipative problems on near-term quantum computers
Quantum computers are poised to revolutionize the simulation of quantum-mechanical systems in physics and chemistry. Current quantum computers execute their algorithms imperfectly, due to uncorrected
Lindbladians with multiple steady states: theory and applications
Markovian master equations, often called Liouvillians or Lindbladians, are used to describe decay and decoherence of a quantum system induced by that system's environment. While a natural environment
Generalized Adiabatic Theorem and Strong-Coupling Limits
We generalize Kato's adiabatic theorem to nonunitary dynamics with an isospectral generator. This enables us to unify two strong-coupling limits: one driven by fast oscillations under a Hamiltonian,
Hierarchical classical metastability in an open quantum East model
We study in detail an open quantum generalisation of a classical kinetically constrained model -- the East model -- known to exhibit slow glassy dynamics stemming from a complex hierarchy of


Coherent quantum dynamics in steady-state manifolds of strongly dissipative systems.
This work considers strongly dissipative quantum systems admitting a nontrivial manifold of steady states and shows how one can enact adiabatic coherent unitary manipulations inside this steady-state manifold by adding a weak, time-rescaled, Hamiltonian term into the system's Liouvillian.
Topology by dissipation
Topological states of fermionic matter can be induced by means of a suitably engineered dissipative dynamics. Dissipation then does not occur as a perturbation, but rather as the main resource for
Adiabatic markovian dynamics.
A general framework for decoherence-assisted computation in noiseless codes and a dissipation-driven approach to holonomic computation based on adiabatic dragging of subsystems that is generally not achievable by nondissipative means are proposed.
Steady-state entanglement by engineered quasi-local Markovian dissipation: Hamiltonian-assisted and conditional stabilization
Interestingly, for both entanglement classes, it is shown that quasi-local stabilization may be scalably achieved conditional to initialization of the system in a large, appropriately chosen subspace.
Constrained dynamics via the Zeno effect in quantum simulation: implementing non-Abelian lattice gauge theories with cold atoms.
We show how engineered classical noise can be used to generate constrained Hamiltonian dynamics in atomic quantum simulators of many-body systems, taking advantage of the continuous Zeno effect.
Non-Abelian Berry connections for quantum computation
In the holonomic approach to quantum computation, information is encoded in a degenerate eigenspace of a parametric family of Hamiltonians and manipulated by the associated holonomic gates. These are
Analysis of quantum semigroups with GKS Lindblad generators: II. General
Semigroups describing the time evolution of open quantum systems in finite-dimensional spaces have generators of a special form, known as Lindblad generators. These generators and the corresponding
Dissipative preparation of entanglement in optical cavities.
This analysis indicates that dissipative state preparation is more than just a new conceptual approach, but can allow for significant improvement as compared to preparation protocols based on coherent unitary dynamics.
Symmetrizing Evolutions
Exponential rise of dynamical complexity in quantum computing through projections
It is shown that the mere frequent observation of a small part of a quantum system can turn its dynamics from a very simple one into an exponentially complex one, capable of universal quantum computation.
