Partially entangled
WebAn entanglement concentration protocol in photonic collective-rotating decoherence-free subspace (CRDFS) is proposed. To accomplish the scheme, two methods to construct parity measurement devices in CRDFS are presented by exploiting the cross-Kerr nonlinearity, through which partially entangled states are converted to maximally entangled states. Web1 Feb 2015 · Based on this point, an efficient and secure quantum communication scheme with partially entangled states is presented. In our scheme, the source node performs …

Web4 Entangled states Generally speaking, for a large system with N-particles, in a pure state Y(q1;::;q N). Let us ask what is the state that particle one is in? The answer is that the state of particle one cannot be described by a wavefunction, but in a mixed state. Let us consider a system composed of two subsystems with coordinates q1 and q2 for WebInterestingly, for higher decoherence, the robustness of partially entangled states increases with increase in the degree of entanglement and then decreases as one approaches the …
WebWe construct a new quantum channel composed of two multi-particle partially entangled states for quantum teleportation (QT). Two explicit controlled probabilistic teleportation tripartite schemes are proposed for arbitrary three-particle partially entangled GHZ state and W state by using our constructed channel. The arbitrary GHZ state and W state can be … Web21 Jan 2024 · Abstract: We investigate how much randomness can be extracted from a generic partially entangled pure state of two qubits in a device-independent setting, where …
WebThis protocol simulates partially entangled two qubit state correlations in the worst case scenario. Our protocol is an improvement on previous protocols which used cbit communication (for example 2 cbit communication in Toner and Bacon model [4]) and non-local boxes (four PR-box and one M-box in BGPS model [12]), as it uses only one M-box …
Web14 Jan 2015 · We present two nonlocal entanglement concentration protocols (ECPs) to distill a subset of N -photon systems in a Greenberger-Horne-Zeilinger (GHZ) state or a W state from a set of photon systems in a partially entangled GHZ-like pure state or a less-entangled W-like state with known parameter, respectively.
