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…
Spread complexity and quantum chaos for periodically driven spin chains
Amin A. Nizami, Ankit W. Shrestha
The complexity of quantum states under dynamical evolution can be investigated by studying the spread with time of the state over a pre-defined basis. It is known that this complex…
Krylov construction and complexity for driven quantum systems
Amin A. Nizami, Ankit W. Shrestha
Krylov complexity is an important dynamical quantity with relevance to the study of operator growth and quantum chaos, and has recently been much studied for various time-independe…
