Entanglement purification protocols (EPPs) and quantum error-correcting codes (QECCs) provide two ways of protecting quantum states from interaction with the environment. In an EPP, perfectly entangled pure states are extracted, with some yield D, from a mixed state M shared by two parties; with a QECC, an arbitrary quantum state |\ensuremath{\xi}〉 can be transmitted at some rate Q through a noisy channel \ensuremath{\chi} without degradation. We prove that an EPP involving one-way classical…

### Quantum entanglement capacity with classical feedback

This work presents a general scheme to convert any quantum error-correcting codes into adaptive protocols for this newly defined quantity of the quantum depolarizing channel, and illustrates with the repetition code and Shor code.

### Two-Way Entanglement Purification for Finite Block Size

• Computer Science
• 2009
This work considers the analog of the minimum distance problem for QECCs, and shows that 2-EPPs can exceed the quantum Hamming bound and the quantum Singleton bound, and achieves the rate k/n = 1− 3 log2 t/n− h(t/n)−O(1/ n) (asymptotically reaching the quantumHamming bound).

An error-correcting protocol assisted by two-way noisy communication that is more easily realisable: all quantum communication is subjected to general noise and all entanglement is created locally without additional resources consumed.

In this network, it is shown how corrections arise to the Ryu-Takayanagi formula in the case of entangled input state, and that the bound on the entanglement entropy of the boundary state is saturated for absolutely maximally entangled input states.

### On entanglement distillation and quantum error correction for unknown states and channels

We consider the problem of invariance of distillable entanglement D and quantum capacities Q under erasure of information about single copy of quantum state or channel respectively. We argue that any

### Two-sided bounds on minimum-error quantum measurement, on the reversibility of quantum dynamics, and on maximum overlap using directional iterates

In a unified framework, we estimate the following quantities of interest in quantum information theory: (1) the minimum-error distinguishability of arbitrary ensembles of mixed quantum states; (2)

### Multiparty quantum protocols for assisted entanglement distillation

This work extends the notion of entanglement of assistance to arbitrary states and gives a protocol for extracting pure Entanglement, a new protocol for the task of multiparty state merging, which does not require time-sharing for distributed compression of two senders.

### A remark on quantum key distribution with two way communication: the classical complexity in decoding the CSS code can be removed

This protocol shows that, this type of 2-EPP protocol can be reduced to an equivalent prepare and measure protocol, and the huge complexity of decoding the classical CSS code is totally removed.

### Quantum Versus Classical Advantages in Secret Key Distillation (and Their Links to Quantum Entanglement)

• Physics
• 2015
We consider the extraction of shared secret key from correlations that are generated by either a classical or quantum source. In the classical setting, two honest parties (Alice and Bob) use public

### Extracting quantum entanglement (general entanglement purification protocols)

• Computer Science
Proceedings 17th IEEE Annual Conference on Computational Complexity
• 2002
It is proved that, on average, Alice and Bob cannot increase the fidelity of the input state significantly, and there exist protocols that may fail with a small probability, and otherwise will output states arbitrarily close to EPR pairs with very high probability.
