Optimizing Variational Quantum Algorithms using Pontryagin's Minimum Principle
Zhi-Cheng Yang, Armin Rahmani, Alireza Shabani +2
We use Pontryagin's minimum principle to optimize variational quantum algorithms. We show that for a fixed computation time, the optimal evolution has a bang-bang (square pulse) fo…
Optimal diabatic dynamics of Majorana-based quantum gates
Armin Rahmani, Babak Seradjeh, Marcel Franz
In topological quantum computing, unitary operations on qubits are performed by adiabatic braiding of non-Abelian quasiparticles, such as Majorana zero modes, and are protected fro…
Anti-Kibble-Zurek Behavior in Crossing the Quantum Critical Point of a Thermally Isolated System Driven by a Noisy Control Field
Anirban Dutta, Armin Rahmani, Adolfo del Campo
We show that a thermally isolated system driven across a quantum phase transition by a noisy control field exhibits anti-Kibble-Zurek behavior, whereby slower driving results in hi…
