The general structure of the decoherence-free subalgebra for uniformly continuous quantum Markov semigroups

Abstract

By using the decomposition of the decoherence-free subalgebra N(T) in direct integrals of factors, we obtain a structure theorem for every uniformly continuous quantum Markov semigroup. Moreover, we prove that when there exists a faithful normal invariant state, N(T) has to be atomic and decoherence takes place.

Structure of Uniformly Continuous Quantum Markov Semigroups with Atomic Decoherence-free Subalgebra

Franco Fagnola, Emanuela Sasso, Veronica Umanità

We establish the structure of uniformly continuous quantum Markov semigroups with atomic decoherence-free subalgebra and apply the result to derive a natural decomposition of a Markovian open quantum system into its noiseless (decoherence-free) and irreducible (ergodic) components. We deduce the structure of invariant states and a method for finding decoherence-free subsystems and subspaces. The relationship between environment induced decoherence and the decoherence-free subalgebra is also discussed.

Structure of covariant uniformly continuous Quantum Markov Semigroups

Nicolò Ginatta

In this thesis I analyze the structure of decoherence-free subalgebra N(T) of a uniformly continuous covariant Quantum Markov Semigroup (QMS) with respect to a representation ? of a compact group G on a Hilbert space h. In particular, I obtain that, when ? is irreducible, N(T) is isomorphic to (?(k) ? 1m)^d for suitable Hilbert spaces k and m, and an integer d related to the connected components of G. I extend this result when ? is reducible and N(T) is atomic by the decomposition of h due to the Peter?Weyl theorem. The thesis is then concluded by exploring the possibility of extending these results beyond the direct sum by using the concept of direct integral.

Structure of uniformly continuous quantum Markov semigroups

The structure of uniformly continuous quantum Markov semigroups with atomic decoherence-free subalgebra is established providing a natural decomposition of a Markovian open quantum system into its noiseless (decoherence-free) and irreducible (ergodic) components. This leads to a new characterization of the structure of invariant states and a new method for finding decoherence-free subsystems and subspaces. Examples are presented to illustrate these results.

The role of the atomic decoherence-free subalgebra in the study of quantum Markov semigroups

Franco Fagnola, Emanuela Sasso, Veronica Umanità

We show that for a Quantum Markov Semigroup (QMS) with a faithful normal invariant state, atomicity of the decoherence-free subalgebra and environmental decoherence are equivalent. Moreover, we prove that the predual of the decoherence-free subalgebra is isometrically isomorphic to the subspace of reversible states. We also describe, in an explicit and constructive way, the relationship between the decoherence-free subalgebra and the fixed point subalgebra.

Relationships between the decoherence-free algebra and the set of fixed points

Franco Fagnola, Emanuela Sasso, Veronica Umanità

We show that, for a Quantum Markov Semigroup (QMS) with a faithful normal invariant state, the atomicity of the decoherence-free subalgebra and environmental decoherence are equivalent. Moreover, we characterize the set of reversible states and explicitly describe the relationship between the decoherence-free subalgebra and the fixed point subalgebra for QMSs with the above equivalent properties.

The Decoherence-Free Subalgebra of Gaussian Quantum Markov Semigroups

Julián Agredo, Franco Fagnola, Damiano Poletti

Abstract We demonstrate a method for finding the decoherence-free subalgebra $${\mathcal {N}}({\mathcal {T}})$$ N ( T ) of a Gaussian quantum Markov semigroup on the von Neumann algebra $${\mathcal {B}}(\Gamma (\mathbb {C}^d))$$ B ( Γ ( C d ) ) of all bounded operator on the Fock space $$\Gamma (\mathbb {C}^d)$$ Γ ( C d ) on $$\mathbb {C}^d$$ C d . We show that $${\mathcal {N}}({\mathcal {T}})$$ N ( T ) is a type I von Neumann algebra $$L^\infty (\mathbb {R}^{d_c};\mathbb {C}){\overline{\otimes }}{\mathcal {B}}(\Gamma (\mathbb {C}^{d_f}))$$ L ∞ ( R d c ; C ) ⊗ ¯ B ( Γ ( C d f ) ) determined, up to unitary equivalence, by two natural numbers $$d_c,d_f\le d$$ d c , d f ≤ d . This result is illustrated by some applications and examples.
