Bell state

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. The Bell's states are a form of e
Quantum circuit that performs Bell decoding. Bell states are sometimes called EPR pairs. Notice that the circuit that decodes the Bell state is the adjoint to the circuit that encodes, or creates, Bell states (described above).
Quantum circuit for teleporting a qubit
In quantum physics, a measurement is the testing or manipulation of a physical system to yield a numerical result. A fundamental feature of quantum theory is that the predictions it makes are probabil
Niels Bohr and Albert Einstein, pictured here at Paul Ehrenfest's home in Leiden (December 1925), had a long-running collegial dispute about what quantum mechanics implied for the nature of reality.
