Four qubit time-bin entangled GHZ-state generation

Abstract

A pair of time-bin entangled states are generated using the spontaneous parametric down-conversion process in two PPLN crystals. One photon from either source interferes on an optical switch. A four-qubit GHZ-state is generated by post-selecting the photons at all the four output ports.

Quantum-entangled photon pair sources are one of the key building blocks for applications\nin quantum metrology, quantum information processing and computing, and quantum\nkey distribution (QKD). The generation of entangled photon pairs in various forms (ie\npolarization entanglement, energy-time entanglement and time-bin entanglement) has been\ndemonstrated through spontaneous parametric downconversion (SPDC) in diverse second-\norder nonlinear media (eg bulk nonlinear crystals).

Entanglement Swapping with independent CW-Sources

M. Halder, A. Beveratos, Corentin Jorel +4 more

We present an entanglement swapping experiment realized for the first time with independent photon pairs created in continuous wave (CW) mode. Pairs of entangled photons are created by the process of spontaneous parametric down conversion in nonlinear periodically poled lithium niobate (PPLN) waveguide crystals. Two photons, one from each pair are combined on a beamsplitter (BS) and projected via a joint measurement onto one of the four Bell states.

Generation of a time–bin Greenberger–Horne–Zeilinger state with an optical switch

Hsin-Pin Lo, Takuya Ikuta, Koji Azuma +3 more

Abstract Multipartite entanglement is a critical resource in quantum information processing that exhibits much richer phenomenon and stronger correlations than in bipartite systems. This advantage is also reflected in its multi-user applications. Although many demonstrations have used photonic polarization qubits, polarization-mode dispersion confines the transmission of photonic polarization qubits through an optical fiber. Consequently, time–bin qubits have a particularly important role to play in quantum communication systems. Here, we generate a three-photon time–bin Greenberger–Horne–Zeilinger (GHZ) state using a 2 × 2 optical switch as a time-dependent beam splitter to entangle time–bin Bell states from a spontaneous parametric down-conversion source and a weak coherent pulse. To characterize the three-photon time–bin GHZ state, we performed measurement estimation, showed a violation of the Mermin inequality, and used quantum state tomography to fully reconstruct a density matrix, which shows a state fidelity exceeding 70%. We expect that our three-photon time–bin GHZ state can be used for long-distance multi-user quantum communication.
