Total teleportation of a single-photon state
نویسندگان
چکیده
Recent demonstrations of teleportation have transferred quantum information encoded into either polarization or fieldquadrature degrees of freedom (DOFs), but an outstanding question is how to simultaneously teleport quantum information encoded into multiple DOFs. We describe how the transverse-spatial, spectral and polarization states of a single photon can be simultaneously teleported using a pair of multimode, polarization-entangled photons derived from spontaneous parametric down-conversion. Furthermore, when the initial photon pair is maximally entangled in the spatial, spectral, and polarization DOFs then the photon’s full quantum state can be reliably teleported using a Bell-state measurement based on sum-frequency generation.

Transfer of different types of optical qubits over a lossy environment
We compare three different types of optical qubits for information transfer via quantum teleportation and direction transmission under photon losses. The three types of qubits are (1) qubits using the vacuum and the single-photon (VSP) states, (2) single-photon qubits using polarization degrees of freedom, i.e., polarized single-photon (PSP) qubits, and (3) coherent-state qubits that use two co...
متن کاملThe non-deterministic quantum logic operation and teleportation of a vacuum and single photon superposition state via parametric amplifiers
We firstly present an all-optical scheme to implement the non-deterministic quantum logic operation of Knill, Laflamme and Milburn (Nature, 409, 4652(2001)). In our scheme, squeezed vacuum state is acted as auxiliary state instead of single photon resources. Then we demonstrate that same setup can be used to teleport a superposition of vacuum and single photon state of the form α|0 > +β|1 > and...

We study an entangled two-mode coherent state within the framework of2×2-dimensional Hilbert space. We investigate the problem of quantum teleportation ofa superposition coherent state via an entangled coherent channel. By three differentmeasures with the titles ``minimum assured fidelity (MASF)”, ``average teleportationfidelity” and ``optimal fidelity (f)” we study the ...
متن کاملQuantum scissors: Teleportation of single-mode optical states by means of a nonlocal single photon
– We employ the quantum state of a single photon entangled with the vacuum (|1〉A|0〉B −|0〉A|1〉B), generated by a photon incident upon a symmetric beam splitter, to teleport single-mode quantum states of light by means of the Bennett protocol. The teleportation of coherent states results in the truncation of their Fock expansion to the first two terms. We analyze the teleported ensembles by means...
متن کاملReliable Teleportation of Ionic Motional States Through a Mapping Process
We show how to teleport reliably an arbitrary superposition of n = 0 and n = 1 vibrational number state between two distant ions. This is done by first mapping the vibrational state to be teleported into the internal degrees of freedom of a given ion. Then we handle with the internal superposition state following Bennett’s original protocol and a recently proposed technique for teleportation of...
