Scalable Acceleration of Many-Body Quantum Dynamics via Time-Rescaling
Edson B. de Almeida Filho, Ãngelo F. da Silva França, Bertúlio de Lima Bernardo
Fast quantum control is essential to overcome decoherence in contemporary quantum platforms, yet achieving this in many-body systems remains a major challenge. We show that the tim…
Thermodynamics of ancilla-assisted erasure of quantum information
Carlos Octavio A. Ribeiro Neto, Bertúlio de Lima Bernardo
Landauer's principle sets a fundamental limit on the heat dissipated when one classical bit of information is erased from a memory, thereby establishing a direct link between infor…
Accelerating Feedback-Based Quantum Algorithms through Time Rescaling
L. A. M. Rattighieri, G. E. L. Pexe, B. L. Bernado +1
This work investigates the impact of time rescaling on the performance of Feedback Quantum Algorithms (FQA) and their variant for optimization tasks, FALQON. We introduce TR-FQA an…
Shortcuts to adiabaticity designed via time-rescaling follow the same transitionless route
J. L. Montenegro Ferreira, Ãngelo F. da Silva França, Alexandre Rosas +1
Time-rescaling (TR) has been recently proposed as a method to engineer fast processes, also known as shortcuts to adiabaticity (STA), which enables the coherent control of quantum…
