Phys. Rev. A 71, 012302 (2005) [5 pages]Relativistically invariant quantum informationReceived 15 March 2004; revised 21 September 2004; published 4 January 2005 We show that quantum information can be encoded into entangled states of multiple indistinguishable particles in such a way that any inertial observer can prepare, manipulate, or measure the encoded state independent of their Lorentz reference frame. Such relativistically invariant quantum information is free of the difficulties associated with encoding into spin or other degrees of freedom in a relativistic context. © 2005 The American Physical Society URL:
