An interaction between a qubit of A and a qubit of B can be realized by first teleporting A's qubit to B, then letting it interact with B's qubit (which is now a LOCC operation, since both qubits are in B's lab) and then teleporting the qubit back to A. Two maximally entangled states of two qubits are used up in this process.
An important distinguishing feature between qubits and classical bits is that multiple qubits can exhibit quantum entanglement; the qubit itself is an exhibition of quantum entanglement. In this case, quantum entanglement is a local or nonlocal property of two or more qubits that allows a set of qubits to express higher correlation than is ...
The W state is an entangled quantum state of three qubits which in the bra-ket notation has the following shape | = (| + | + | ) and which is remarkable for representing a specific type of multipartite entanglement and for occurring in several applications in quantum information theory.

The resources required for quantum teleportation are a communication channel capable of transmitting two classical bits, a means of generating an entangled Bell state of qubits and distributing to two different locations, performing a Bell measurement on one of the Bell state qubits, and manipulating the quantum state of the other qubit from ...
In quantum information science, the Bell's states or EPR pairs are specific quantum states of two qubits that represent the simplest examples of quantum entanglement. [1]: 25 The Bell's states are a form of entangled and normalized basis vectors.
Measurement of one of the qubits collapses the entire quantum state, that span the two qubits. The GHZ state is a similar entangled quantum state that spans three or more qubits. This type of value-assignment occurs instantaneously over any distance and this has as of 2018 been experimentally verified by QUESS for distances of up to 1200 ...
In quantum physics, the "monogamy" of quantum entanglement refers to the fundamental property that it cannot be freely shared between arbitrarily many parties. In order for two qubits A and B to be maximally entangled , they must not be entangled with any third qubit C whatsoever.
