Amplification of quantum transfer and quantum ratchet
Sergei Kozyrev, Alexander Pechen
Amplification of quantum transfer and ratchet--type processes are important for quantum technologies. We also expect that quantum ratchet works in quantum photosynthesis, where pos…
Quantum control landscape for generation of and gates in an open qubit with both coherent and environmental drive
Vadim Petruhanov, Alexander Pechen
An important problem in quantum computation is generation of single-qubit quantum gates such as Hadamard () and () gates which are components of a universal set of gate…
Control landscape of measurement-assisted transition probability for a three-level quantum system with dynamical symmetry
Maria Elovenkova, Alexander Pechen
Quantum systems with dynamical symmetries have conserved quantities which are preserved under coherent controls. Therefore such systems can not be completely controlled by means of…
Optimal State Manipulation for a Two-Qubit System Driven by Coherent and Incoherent Controls
Oleg Morzhin, Alexander Pechen
Optimal control of two-qubit quantum systems attracts high interest due to applications ranging from two-qubit gate generation to optimization of receiver for transferring coherenc…
Quantum Gate Generation in Two-Level Open Quantum Systems by Coherent and Incoherent Photons Found with Gradient Search
Vadim Petruhanov, Alexander Pechen
In this work, we consider an environment formed by incoherent photons as a resource for controlling open quantum systems via an incoherent control. We exploit a coherent control in…
