Atalhos para Adiabaticidade e Aplicacoes em Computacao Quantica (Shortcuts to Adiabaticity and Applications in Quantum Computation)
It's a concrete attack on adiabatic quantum computing's main weakness — slowness — showing the speed limit is about energy budget, not an intrinsic time floor.
The dissertation introduces two models for universal superadiabatic quantum computing built on counter-diabatic Hamiltonians — one using superadiabatic quantum teleportation as a primitive for arbitrary n-qubit gates, the other using controlled superadiabatic evolutions to implement n-controlled gates with simple time-independent Hamiltonians — and argues via the quantum speed limit that superadiabatic evolution is in principle compatible with arbitrarily small time intervals, constrained by energetic cost.
Why it matters
It's a concrete attack on adiabatic quantum computing's main weakness — slowness — showing the speed limit is about energy budget, not an intrinsic time floor.
Use when: When a theorem limits your speed, check what the limit actually prices — here the "speed limit" prices energy, so the engineering question becomes how much energy you can afford, not how fast physics allows.
