Abstract

By adding an ancilla photon in the fixed polarization state and making good use of quantum parity check, the polarization state of a photonic qubit, which may or may not be entangled to other systems, are successfully protected against collective decoherence.

Distribution of a qubit over collective-noise channel assisted with one additional qubit

Yamamoto, T, Junichi Shimamura, Şahin Kaya Özdemir +2 more

We propose a distribution scheme of polarization states of a single photon over collective-noise channel assisted with one additional photon in a fixed polarization state. Although the present scheme does not encode the polarization state of a photon to an entangled state of two photons in the decoherence-free subspace, the state is protected against collective noise and extracted by a measurement based on the parity check and the post-selection. This scheme will easily be applied to many quantum communication protocols based on qubits.

Inhibition of decoherence in flying qubits

Sajeev Damodarakurup, Marco Lucamarini, Giovanni Di Giuseppe +2 more

In recent years the interest in the manipulation of quantum systems has furthered new strategies for maintaining their coherence, continuously threatened by unwanted and uncontrollable interactions with the environment. Photons interact weakly with the surroundings. Even so decoherence may significantly affect their polarization state during the propagation within dispersive media because of the unavoidable presence of more than a single frequency in the envelope of the photon pulse. Here we report on a suppression of the polarization decoherence in a ring cavity obtained by properly retooling for the photon qubit the "bang-bang" protection technique already employed for nuclear spins and nuclear-quadrupole qubits. Our results show that bang-bang control can be profitably extended to all quantum information processes involving flying polarization qubits.

Generation of arbitrary four-photon polarization-entangled decoherence-free states

Yan-Xiao Gong, Xu‐Bo Zou, Xiao-Ling Niu +3 more

We propose a scheme to generate four-photon polarization-entangled states, which enables the encoding of an arbitrary qubit into a four-qubit decoherence-free subspace robust against collective decoherence. The scheme is based on linear optical elements and postselection strategy, which is feasible with existing experimental technology.

Faithful Qubit Distribution Assisted by One Additional Qubit against Collective Noise

Takashi Yamamoto, Junichi Shimamura, Şahin Kaya Özdemir +2 more

We propose a distribution scheme of polarization states of a single photon over a collective-noise channel. By adding one extra photon with a fixed polarization, we can protect the state against collective noise via a parity-check measurement and postselection. While the scheme succeeds only probabilistically, it is simpler and more flexible than the schemes utilizing decoherence-free subspace. An application to the Bennett-Brassard 1984 protocol through a collective-noise channel, which is robust to the Trojan horse attack, is also given.
