Composite quantum gates simultaneously compensated for multiple errors
Hristo G. Tonchev, Nikolay V. Vitanov
Systematic control errors remain a primary obstacle to realizing high-fidelity single-qubit gates. We introduce composite pulse sequences that implement X and Hadamard gates while…
Improvement of performance of Grover's algorithm on three generations of Heron family IBM QPUs without and with topological dynamical decoupling
Tihomir G. Tenev, Nayden P. Nedev, Nikolay V. Vitanov
We investigate the performance of Grover's algorithm on three different generations of IBM Heron QPUs. On Heron family of IBM QPUs the success probabilities for three, four and fiv…
Ramsey Interferometry in Wigner-Majorana Qudits
Branislav Ilikj, Thomas Zanon-Willette, Nikolay V. Vitanov
Ramsey interferometry estimates a detuning from the phase accumulated between two interaction zones, with a resolution set by the interrogation time . We propose a single-qudit…
Steering quantum transitions between three crossing energy levels
S. S. Ivanov, N. V. Vitanov
We calculate the propagator and the transition probabilities for a coherently driven three-state quantum system. The energies of the three states change linearly in time, whereas t…
