Counterdiabatic Quantum Circuits
Ankit Wenju Shrestha, Budhaditya Bhattacharjee, Adolfo del Campo
Counterdiabatic driving provides a universal route to fast quantum control, but its standard formulation presupposes a Hamiltonian generator. We develop a Hamiltonian-free theory o…
Shortcuts to Adiabaticity for non-Hermitian systems in Krylov Space
Ankit W. Shrestha, Budhaditya Bhattacharjee, Adolfo del Campo
Shortcuts to adiabaticity (STA) reproduce adiabatic dynamics in finite time, but their counterdiabatic implementation relies on the adiabatic gauge potential (AGP), which is diffic…
Double-Bracket Master Equations: Phase-Space Representation and Classical Limit
Ankit W. Shrestha, Budhaditya Bhattacharjee, Adolfo del Campo
We systematically investigate master equations involving double-bracket dissipators in the classical limit. Dissipators defined by double commutators arise naturally in dephasing d…
