Sudden Death of Entanglement Induced by Polarization Mode Dispersion

Abstract

We study the decoherence of polarization-entangled photon pairs subject to the effects of polarization mode dispersion, the chief polarization decoherence mechanism in optical fibers. We show that fiber propagation reveals an intriguing interplay between the concepts of entanglement sudden death, decoherence-free subspaces, and nonlocality. We define the boundaries in which entanglement-based quantum communications protocols relying on fiber propagation can be applied.

Abrupt disappearance of entangelement in fibers with polarization mode dispersion

Cristian Antonelli, Mark Shtaif, Misha Brodsky

We investigate the decoherence of polarization-entangled photon pairs distributed over optical fibers with polarization mode dispersion. We characterize system configurations yielding entanglement sudden death and disappearance of non-locality and show the possibility of non-local compensation. Our results establish the ultimate boundaries for fiber-based quantum communications.

Disentanglement due to polarization mode dispersion in optical fibers: from nonlocal compensation to entanglement sudden death

Misha Brodsky, Cristian Antonelli, Mark Shtaif

We propagate pairs of polarization-entangled photons through optical fibers with polarization-mode dispersion (PMD). We observe non-local PMD compensation and the transition to sudden death of entanglement when the alignment of the compensating element is varied.

Decoherence-free subspace and entanglement sudden death of multi-photon polarization states in fiber channels

Yi‐Wen Liu

Abstract The construction of quantum networks requires long-distance teleportation of multi-qubit entangled states. Here, we investigate the entanglement dynamics of GHZ and W states in fiber channels. In a fiber channel, the two most important phenomena that affect polarization entanglement are polarization mode dispersion (PMD) and polarization-dependent loss (PDL). We theoretically characterize how PMD and PDL vectors affect three-qubit states. In particular, upon quantifying the entanglement at the output states using concurrence and entanglement witnesses, we reveal the occurrence of entanglement sudden death and the appearance of decoherence-free subspaces in tripartite systems. Finally, we explore the evolution of GHZ and W state with an arbitrary number of photons in a fiber network and discuss the decoherence mechanism of the 4-party cluster state.

Propagation of polarization-entangled photon pairs in optical fibers

As polarization-entangled photons traverse through fibers with polarization mode dispersion the degree of their entanglement changes in fascinating ways. We will describe sudden loss and revival of entanglement and also will discuss non-local PMD compensation.

Disappearance of polarization entanglement due to the relative orientation of two fiber's PMD vectors

Misha Brodsky, Cristian Antonelli, Mark Shtaif

We study propagation of polarization-entangled photon pairs through optical fibers with polarization-mode dispersion (PMD). We observe abrupt loss and revival of entanglement as the PMD vector of one fiber rotates relative to the PMD vector of the other fiber.

Stochastic decoherence induced by polarization mode dispersion

Yiwen Liu

We address the propagation of entanglement in fibers and investigate the decoherence of polarization-entangled photon pairs caused by polarization mode dispersion (PMD). We devise a decoherence model starting from the statistical properties of polarization mode dispersion and obtain the density matrix describing initially maximally entangled states at any time. Using these results, we derive how decoherence depends on the length of the fibers. We calculate the mean concurrence of the entangled states with PMD effects as a function of fiber length, bandwidth, and other parameters in different cases.
