Scalable modular architecture for universal quantum computation
Fernando Gago-Encinas, Christiane P. Koch
Universal quantum computing requires the ability to perform every unitary operation, i.e., evolution operator controllability. In view of developing resource-efficient quantum proc…
Determining the ability for universal quantum computing: Testing controllability via dimensional expressivity
Fernando Gago-Encinas, Tobias Hartung, Daniel M. Reich +2
Operator controllability refers to the ability to implement an arbitrary unitary in SU(N) and is a prerequisite for universal quantum computing. Controllability tests can be used i…
Graph test of controllability in qubit arrays: A systematic way to determine the minimum number of external controls
Fernando Gago-Encinas, Monika Leibscher, Christiane P. Koch
The ability to implement any desired quantum logic gate on a quantum processing unit is equivalent to evolution-operator controllability of the qubits. Conversely, controllability…
Krotov: A Python implementation of Krotov's method for quantum optimal control
Michael H. Goerz, Daniel Basilewitsch, Fernando Gago-Encinas +4
We present a new open-source Python package, krotov, implementing the quantum optimal control method of that name. It allows to determine time-dependent external fields for a wide…
