چکیده
We introduce a notion of teleportation scheme between subalgebras semi-finite von Neumann algebras in the commuting operator model locality. Using techniques from subfactor theory, we present unbiased schemes for relative commutants $$N'\cap M$$ large class finite-index inclusions $$N\subseteq tracial algebras, where condition means that no information about teleported observables is contained classical communication sent parties. For N matrix $$M_n({\mathbb {C}})$$ , including those relevant to hybrid classical/quantum codes, show any tight necessarily arises an orthonormal unitary Pimsner–Popa basis over $$N'$$ generalising work Werner (J Phys A 34(35):7081–7094, 2001). Combining our with Brannan–Ganesan–Harris Math 63(11): 112204, 2022) compute quantum chromatic numbers variety graphs arising finite-dimensional .

An operator description of entanglement matching in quantum teleportation
The antilinear operator representation of bipartite pure states of the relative state formulation of quantum mechanics is applied to describe quantum teleportation schemes utilizing an arbitrary pure state as the entangled resource. Bennett type teleportation schemes with nonmaximally entangled pure states are characterized and the notion of ‘entanglement matching’ is introduced in general. Exa...
متن کاملOptimizing Teleportation Cost in Multi-Partition Distributed Quantum Circuits
There are many obstacles in quantum circuits implementation with large scales, so distributed quantum systems are appropriate solution for these quantum circuits. Therefore, reducing the number of quantum teleportation leads to improve the cost of implementing a quantum circuit. The minimum number of teleportations can be considered as a measure of the efficiency of distributed quantum systems....
متن کاملQuantum teleportation.
For continuous variable systems, some protocols for entanglement swapping, establishing entanglement between distant stations through teleportation, testing the efficiency of teleportation with the aid of a third party, and combining teleportation with cloning have been proposed. But no protocol for the explicit teleportation of an entangled continuous variable state exists in the literature, a...
متن کاملQuantum Teleportation
Teleportation the transmission and reconstruction of objects over arbitrary distances is a spectacular process, which actually has been invented by science fiction authors some decades ago. Unbelievable as it seems in 1993 a theoretical scheme has been found by Charles Bennett et al. that predicts the existence of teleportation in reality at least for quantum systems. This scheme exploits some ...
متن کاملQuantum Teleportation
Given a single copy of an unknown quantum state, it is impossible in principle to identify it. The mostly inaccessible information carried by the state is termed quantum information. In contrast to classical information, it cannot be copied or cloned. This concept provides a theoretical underpinning for all aspects of quantum communication and quantum computation. Here we use it to consider qua...
