Decoherence is the phenomenon of non-unitary dynamics that arises as a consequence of coupling between a system and its environment. It has important harmful implications for quantum information processing, and various solutions to the problem have been proposed. Here we provide a detailed a review of the theory of decoherence-free subspaces and subsystems, focusing on their usefulness for preservation of quantum information. 

Review of Decoherence‐Free Subspaces, Noiseless Subsystems, and Dynamical Decoupling

Quantum information requires protection from the adverse affects of decoherence and noise. This review provides an introduction to the theory of decoherence-free subspaces, noiseless subsystems, and

Immunizing quantum information against decoherence via decoherence-free environments

We construct decoherence-free environments (DFEs) within the Hamiltonian formalism and derive an exact equation of motion for a quantum subsystem interacting with a DFE. We discuss the feasibility of

Algebraic Method in the Analysis of Decoherence-Free Subspaces in Open Quantum Systems

This paper will study a general framework of decoherence-free subspaces and provide a criterion for the existence of a deco coherent subspace in open quantum systems.

A recursion formula is derived that characterizes the dimensionality of available decoherence-free subsystems in such a setting as to be affected by collective depolarization.

Quantum Computing in Decoherence-Free Subspace Constructed by Triangulation

A formalism for quantum computing in decoherence-free subspaces is presented. The constructed subspaces are partial triangulated to an index related to environment. The quantum states in the

Decoherence free subspaces for two--access quantum channels

In this paper we consider construction of decoherence free subspaces for two--access random unitary channels. First, we concentrate on hermitian unitary noise model $U$ for a bi--unitary channel and

This work presents an alternative that is based on a combination of a decoherence-free subspace encoding and the application of strong and fast pulses: "encoded recoupling and decoupling" (ERD).

Robust photonic entanglement distribution by state-independent encoding onto decoherence-free subspace

Before the practical implementation of quantum information schemes, there is a need to reduce loss, both in terms of photons and the information they carry. A robust scheme now experimentally



Quantum computing using dissipation to remain in a decoherence-free subspace

A new approach to the implementation of quantum gates is proposed in which decoherence during the gate operations is strongly reduced by making use of an environment induced quantum Zeno effect that confines the dynamics effectively to a decoherent-free subspace.

Decoherence-Free Subspaces for Quantum Computation

It is shown that decoherence-free subspaces are stable to perturbations and, moreover, that universal quantum computation is possible within them.

Experimental verification of decoherence-free subspaces.

Using spontaneous parametric down-conversion, we produce polarization-entangled states of two photons and characterize them using two-photon tomography to measure the density matrix. A controllable

Decoherence-free subspaces for multiple-qubit errors. I. Characterization

Coherence in an open quantum system is degraded through its interaction with a bath. This decoherence can be avoided by restricting the dynamics of the system to special decoherence-free subspaces.

Creating decoherence-free subspaces using strong and fast pulses.

This work gives explicit sequences of strong and fast [bang-bang] pulses that create the conditions allowing for the existence of DFSs that support scalable, universal quantum computation.


The dynamics of a decohering two-level system driven by a suitable control Hamiltonian is studied. The control procedure is implemented as a sequence of radio-frequency pulses that repetitively flip

Decoherence-Free Subspaces for Multiple-Qubit Errors: (II) Universal, Fault-Tolerant Quantum Computation

Decoherence-free subspaces (DFSs) shield quantum information from errors induced by the interaction with an uncontrollable environment. Here we study a model of correlated errors forming an Abelian

Reducing decoherence in quantum-computer memory with all quantum bits coupling to the same environment

Decoherence in quantum-computer memory due to the inevitable coupling to the external environment is examined. We make the assumption that all quantum bits (qubits) interact with the same environment


An operator sum representation is derived for a decoherence-free subspace (DFS) and used to (i) show that DFS’s are the class of quantum error correcting codes (QECC’s) with fixed, unitary recovery

Suppression of decoherence in quantum registers by entanglement with a nonequilibrium environment

It is shown that a nonequilibrium environment can be instrumental in suppressing decoherence between distinct decoherence free subspaces in quantum registers. The effect is found in the framework of
