Efficient bipartite quantum state purification in arbitrary dimensional Hilbert spaces [PDF]

, 2001
A new purification scheme is proposed which applies to arbitrary dimensional bipartite quantum systems. It is based on the repeated application of a special class of nonlinear quantum maps and a single, local unitary operation.

A security proof of quantum cryptography based entirely on entanglement purification [PDF]

, 2001
We give a proof that entanglement purification, even with noisy apparatus, is sufficient to disentangle an eavesdropper (Eve) from the communication channel.

Entanglement purification protocols for all graph states [PDF]

, 2006
We present multiparty entanglement purification protocols that are capable of purifying arbitrary graph states directly. We develop recurrence and breeding protocols and compare our methods with strategies based on bipartite entanglement purification in ...

Entanglement of Purification and Multiboundary Wormhole Geometries [PDF]

, 2019
We posit a geometrical description of the entanglement of purification for subregions in a holographic CFT. The bulk description naturally generalizes the two-party case and leads to interesting inequalities among multi-party entanglements of ...

Entanglement purification of multi-mode quantum states [PDF]

, 2003
An iterative random procedure is considered allowing an entanglement purification of a class of multi-mode quantum states. In certain cases, a complete purification may be achieved using only a single signal state preparation.

Optimized Entanglement Purification [PDF]

, 2019
We investigate novel protocols for entanglement purification of qubit Bell pairs. Employing genetic algorithms for the design of the purification circuit, we obtain shorter circuits achieving higher success rates and better final fidelities than what is ...

Test Case Purification for Improving Fault Localization [PDF]

, 2014
Finding and fixing bugs are time-consuming activities in software development. Spectrum-based fault localization aims to identify the faulty position in source code based on the execution trace of test cases.

Purification of genuine multipartite entanglement

, 2011
In tasks, where multipartite entanglement plays a central role, state purification is, due to inevitable noise, a crucial part of the procedure.

Optimal purification of thermal graph states [PDF]

, 2006
In this paper, a purification protocol is presented and its performance is proven to be optimal when applied to a particular subset of graph states that are subject to local Z-noise.
