Quantum Information Processing and Relativistic Quantum Fields
Dionigi M. T. Benincasa, Leron Borsten, Michel Buck +1
It is shown that an ideal measurement of a one-particle wave packet state of a relativistic quantum field in Minkowski spacetime enables superluminal signalling. The result holds f…
