  2. 3-QUBIT FRIDGE

  3. 3-QUBIT FRIDGE DESIGN

  4. 3-QUBIT FRIDGE DESIGN INTERACTION

  5. 3-QUBIT FRIDGE DESIGN INTERACTION BIAS COOLING

  6. THE MODEL FREE HAMILTONIAN WITH

  7. THE MODEL FREE HAMILTONIAN WITH INTERACTION

  8. THE MODEL FREE HAMILTONIAN WITH INTERACTION THERMALISATION  RESET QUBIT TO THERMAL STATE

  9. THE MODEL FREE HAMILTONIAN WITH INTERACTION THERMALISATION  RESET QUBIT TO THERMAL STATE WEAK COUPLING REGIME

  10. SOLVING THE MODEL MASTER EQUATION DISSIPATOR (LINDBLAD) STEADY STATE TRACELESS MATRIX ≈ BIAS BETWEEN POPULATIONS OF |010> AND |101>

  11. AROUND CARNOT POINT STEADY STATE BIAS TRACELESS MATRIX

  12. AROUND CARNOT POINT STEADY STATE BIAS TRACELESS MATRIX CARNOT POINT

  13. AROUND CARNOT POINT STEADY STATE BIAS TRACELESS MATRIX CARNOT POINT ALSO TRUE AROUND CARNOT (BALL OF SEP STATES)

  14. AROUND CARNOT POINT STEADY STATE BIAS TRACELESS MATRIX CARNOT POINT ALSO TRUE AROUND CARNOT (BALL OF SEP STATES) ENTANGLEMENT IS DETRIMENTAL FOR EFFICIENCY

  15. ENTANGLEMENT? STEADY STATE WHERE

  16. ENTANGLEMENT? STEADY STATE WHERE ENTANGLEMENT WITNESSES MEASURE OF ENTANGLEMENT GUHNE & SEEVINCK NJP 2010, HUBER et al. PRL 2010

  17. ENTANGLEMENT ZOO 1. ENTANGLEMENT BETWEEN ANY BIPARTITION 2. GENUINE TRIPARTITE ENTANGLEMENT

  18. ENTANGLEMENT ZOO 1. ENTANGLEMENT BETWEEN ANY BIPARTITION 2. GENUINE TRIPARTITE ENTANGLEMENT DOES THIS ENTANGLEMENT PLAY ANY ROLE?

  19. COOLING CONSIDER A GIVEN OBJECT (QUBIT) TO BE COOLED FIX: ENERGY, BATH (TEMPERATURE TC, COUPLING)

  20. COOLING CONSIDER A GIVEN OBJECT (QUBIT) TO BE COOLED FIX: ENERGY, BATH (TEMPERATURE TC, COUPLING p1) CONSIDER GIVEN RESSOURCES: HOT BATH (TH) COLD BATH (TR)

  21. COOLING CONSIDER A GIVEN OBJECT (QUBIT) TO BE COOLED FIX: ENERGY, BATH (TEMPERATURE TC, COUPLING p1) CONSIDER GIVEN RESSOURCES: HOT BATH (TH) COLD BATH (TR) 1. OPTIMIZE COOLING  TS (LOWEST T FOR QUBIT) FREE PARAMETERS: E2 and g, p2, p3 << Ei

  22. COOLING CONSIDER A GIVEN OBJECT (QUBIT) TO BE COOLED FIX: ENERGY, BATH (TEMPERATURE TC, COUPLING p1) CONSIDER GIVEN RESSOURCES: HOT BATH (TH) COLD BATH (TR) 1. OPTIMIZE COOLING  TS (LOWEST T FOR QUBIT) FREE PARAMETERS: E2 and g, p2, p3 << Ei 2. OPTIMIZE COOLING IMPOSING SEPARABILITY TS*

  23. COOLING ENHANCEMENT RELATIVE COOLING ENHANCEMENT

  24. COOLING ENHANCEMENT RELATIVE COOLING ENHANCEMENT NO ENHANCEMENT

  25. COOLING ENHANCEMENT MONOTONOUS RELATION BTW COOLING ENHANCEMENT AND ENTANGLEMENT (CONCURRENCE)

  26. COOLING ENHANCEMENT MONOTONOUS RELATION BTW COOLING ENHANCEMENT AND ENTANGLEMENT (CONCURRENCE) FUNCTIONAL RELATIONSHIP?

  27. ENERGY TRANSPORT ENTANGLEMENT: ENERGY IN / ENERGY OUT

  28. OPEN QUESTIONS • BEYOND WEAK COUPLING REGIME • OTHER MODELS • MACROSCOPIC FRIDGES • HEAT ENGINES • QUANTUM EFFECTS IN BATHS
