It may seem inevitable that highly entangled quantum states are susceptible to disturbance through interaction with a decohering environment. However, certain multiqubit entangled states are well protected from common forms of decoherence as the quantum information is hidden in inherently nonlocal degrees of freedom. This review shows that this robustness is enabled by specific measurements on subsets of qubits, implementing a quantum version of an error correction process. Beginning with the… Expand
Protecting quantum entanglement by repetitive measurement
TLDR
The theory of quantum error correction (QEC) overcomes complications by encoding quantum information in entangled states of many qubits and performing parity measurements to identify errors in the system without destroying the encoded information. Expand

TLDR
A clear concept of the architectural solutions to scalable quantum computing is emerging, with relatively new discoveries of unique features of quantum entanglement showing that effective use of redundancy should make possible the solution of the quantum memory problem. Expand
Improving the Robustness of Entangled States by Basis Transformation
TLDR
It is shown that the robustness of cat-like entangled states is not only related to the overall noise strength and error distribution parameters, but also to the basis of qubits, which implies that one could improve the intrinsic robustity of entangled states by simply transforming the qubit basis at the right moment.

Optimal qubit-bases for preserving two-qubit entanglement against Pauli noises
TLDR
It is shown that the optimal qubit-bases are not the same in different cases and these results are expected to serve entanglement-based quantum protocols of which the real-world success or high-quality implementation relies on the longevity ofEntanglement in two-particles or multi-particle quantum states.

Repeated multi-qubit readout and feedback with a mixed-species trapped-ion register
TLDR
Up to 50 sequential measurements of correlations between two beryllium ion microwave qubits using an ancillary optical qubit in a calcium ion are demonstrated, and feedback is implemented that allows us to stabilize two-qubit subspaces as well as Bell states, a class of maximally entangled states.

It is shown that topological protection can be viewed as a Hamiltonian realization of error correction: for a quantum code for which the minimal number of errors that remain undetected is N, the corresponding Hamiltonian model of the effects of the environment noise appears only in the Nth order of the perturbation theory.
