    "abstract": "We calculate the radiation resulting from the Unruh effect for strongly\naccelerated electrons and show that the photons are created in pairs whose\npolarizations are maximally entangled. Apart from the photon statistics, this\nquantum radiation can further be discriminated from the classical (Larmor)\nradiation via the different spectral and angular distributions. The signatures\nof the Unruh effect become significant if the external electromagnetic field\naccelerating the electrons is not too far below the Schwinger limit and might\nbe observable with future facilities. Finally, the corrections due to the\nbirefringent nature of the QED vacuum at such ultra-high fields are discussed.\nPACS: 04.62.+v, 12.20.Fv, 41.60.-m, 42.25.Lc.",
