  1. Entanglement between Fermionic cavities in non-uniform motion Antony Lee University of Nottingham N. Friis, A.R.L., D.E. Brushci & J. Louko

  2. Outline • Recap of cavities • Fermionic fields • Outcomes • Open problems

  3. Rindler Co-ords • Accelerated observer sees thermal bath • Degrades entanglement

  4. Non-Uniform Motion • Cavities allow for arbitrary motion • Can construct realistic trajectories • Potential for experiments III η=const II I

  5. Right mover • Left and Right movers decouple • Consider superposition of both Left mover Inertial Accelerated

  6. Results Particle Antiparticle Solid line - S=1/2 Dashed line - S=1/4 Black - S=0 • Bosons and Fermions qualitatively similar • Corrections are periodic N. Friis, A.R.L, D. E.Bruschiand J. Louko: In preparation

  7. Problems/ Questions • Experimental Observations • Localisation of states • Quantum Cryptography

  8. Conclusions • Considered non-uniform trajectory • Cavities are physical objects • Potential for experimental observations • Could help with known problems
