Concurrent Remote Entanglement with Quantum Error Correction
Remote entanglement of distant, non-interacting quantum entities is a key primitive for quantum information processing. We present a new protocol to remotely entangle two stationary qubits by first entangling them with propagating ancilla qubits and then performing a joint two-qubit measurement on the ancillas. Subsequently, single-qubit measurements are performed on each of the ancillas. We de...
متن کاملMixed-state entanglement and quantum error correction.
Entanglement purification protocols (EPP) and quantum errorcorrecting codes (QECC) 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 bipartite mixed state M ; with a QECC, an arbitrary quantum state |ξ〉 can be transmitted at some rate Q through a noisy channel χ without degrada...
متن کاملEntanglement purification and quantum error correction
We give a review on entanglement purification for bipartite and multipartite quantum states, with the main focus on theoretical work carried out by our group in the last couple of years. We discuss entanglement purification in the context of quantum communication, where we emphasize its close relation to quantum error correction. Various bipartite and multipartite entanglement purification prot...

متن کاملEntanglement and perfect quantum error correction
. (1) This situation describes the transmission of “quantum information” (the entanglement between R and Q) via a noisy quantum channel. For example, imagine that RQ is a quantum computing device. The overall state of the device is entangled. Subsystem Q is imperfectly isolated from the environment, and thus experiences noise and distortion given by E . The problem of sending entanglement throu...
