Quantum systems are always subject to interactions with an environment, typically resulting in decoherence and distortion of quantum correlations. It has been recently shown that a controlled interaction with the environment may actually help to create a state, dubbed as {\em ``dark''}, which is immune to decoherence. To encode quantum information in the dark states, they need to span a space with a dimensionality larger than one, so different orthogonal states act as a computational basis. We… Expand

Symmetry-protected dissipative preparation of matrix product states
We propose and analyze a method for efficient dissipative preparation of matrix product states that exploits their symmetry properties. Specifically, we construct an explicit protocol that makes useExpand
Quantum state tomography across the exceptional point in a single dissipative qubit
Open systems with gain and loss, described by non-trace-preserving, non-Hermitian Hamiltonians, have been a subject of intense research recently. The effect of exceptional-point degeneracies on theExpand

We study the null space degeneracy of open quantum systems with multiple non-Abelian, strong symmetries. By decomposing the Hilbert space representation of these symmetries into an irreducibleExpand
Coherent oscillations inside a quantum manifold stabilized by dissipation
Manipulating the state of a logical quantum bit usually comes at the expense of exposing it to decoherence. Fault-tolerant quantum computing tackles this problem by manipulating quantum informationExpand

We theoretically study the driven-dissipative Harper-Hofstadter model on a two-dimensional square lattice in the presence of a weak harmonic trap. Without pumping and loss, the eigenstates of thisExpand
Stabilizing Entanglement via Symmetry-Selective Bath Engineering in Superconducting Qubits.
D dissipative stabilization of entanglement between two superconducting transmon qubits is demonstrated in a symmetry-selective manner and suppression of the Bell state of opposite symmetry due to parity selection rules is demonstrated. Expand

Observation of many-body localization of interacting fermions in a quasirandom optical lattice
This experiment experimentally observed this nonergodic evolution for interacting fermions in a one-dimensional quasirandom optical lattice and identified the MBL transition through the relaxation dynamics of an initially prepared charge density wave. Expand
