We show that in the presence of arbitrary catalysts, any pure bipartite entangled state can be converted into any other to unlimited accuracy without the use of any communication, quantum or classical. The interconvertibility of entangled quantum states is an important question in quantum information theory, both for its own sake and because of its connec-tions to quantum error correction [2], quantum cryptography [5] and quantum communication complexity [1]. In 1999, Nielsen and Hardy supplied…

Quantum Teleportation and Super-Dense Coding in Operator Algebras

We show for any $d,m\ge 2$ with $(d,m)\neq (2,2)$, the matrix-valued generalization of the (tensor product) quantum correlation set of $d$ inputs and $m$ outputs is not closed. Our argument uses a

Multi-Party Quantum Purity Distillation with Bounded Classical Communication

TLDR
A protocol is provided for three parties, Alice, Bob and Charlie, to distill local purity from many independent copies of a given quantum state ρ<sup>ABC</sup>, to minimize the usage of the dephasing channel while maximizing the asymptotic purity.

Separation of quantum, spatial quantum, and approximate quantum correlations

Quantum nonlocal correlations are generated by implementation of local quantum measurements on spatially separated quantum subsystems. Depending on the underlying mathematical model, various notions

Universal quantum computation in a hidden basis

TLDR
The results to quantum-public-key authentication protocols are applied, by showing that anatural class of digital signature schemes for classical messages is insecure and an efficient algorithm for state preparation that is efficient for some classes of states (e.g. symmetric states).

METHOD OF AREAS FOR MANIPULATING THE ENTANGLEMENT PROPERTIES OF ONE COPY OF A TWO-PARTICLE PURE ENTANGLED STATE

We consider the problem of how to manipulate the entanglement properties of a general two-particle pure state, shared between Alice and Bob, by using only local operations at each end and classical

Entanglement-Assisted Local Manipulation of Pure Quantum States

We demonstrate that local transformations on a composite quantum system can be enhanced in the presence of certain entangled states. These extra states act much like catalysts in a chemical reaction:

Entanglement of pure states for a single copy

A quantification of such an entanglement of a single copy of a pure state is proposed by means of a finite minimal set of new measures from which the optimal probability of conversion follows.

An exponential gap is established between quantum and classical sampling complexity, for the set disjointness function, which is the first exponential gap for any task where the classical probabilistic algorithm is allowed to err.
