RECOVERY AND RECONSTRUCTION IN QUANTUM SYSTEMS
… I discuss two such schemes, namely the recovery channel and the quantum error correction, and various scenarios in which they are applied. The first scenario is the perfect recovery in the Gaussian fermionic systems. When therelative entropy between two states remains unchanged under a …

STUDIES IN QUANTUM CONTROL AND QUANTUM INFORMATION
… control protocols designed for cooling, error recovery, and quantum metrology. The physical platforms utilized in this work include qubits, quantum harmonic oscillators, and their composite systems. In the first project, we propose a physical implementation of a symmetry-protected …
