DESCRIPTION: Abstract:I present the main projects of my doctoral thesis\, 
 whose aim is to understand the energy requirements and limitations of quan
 tum information processing. First\, we demonstrate classical logic process
 ing using a trapped-ion quantum computer. A three-bit half-adder is implem
 ented using electronic states of trapped ions. We discuss the energetics b
 y measuring consumed power and theoretical modeling. Second\, we investiga
 te energy-fidelity trade-offs when implementing unitaries in driven quantu
 m systems. The fidelity of the operation is quantified by tracing out the 
 degrees of freedom of the driving system\, and rigorous mathematical bound
 s are sought for fidelity guarantees independent of the unitary operation.
  Finally\, the implications of these mathematical bounds are explored in g
 eneral quantum algorithms using the framework of Quantum Singular Value Tr
 ansforms (QSVT)\, including the impact of error correction on error-energy
  scaling.
