Coupling-assisted Landau-Majorana-Stuckelberg-Zener transition in two-interacting-qubit systems
R. Grimaudo, N. V. Vitanov, A. Messina
We analyse a system of two interacting spin-qubits subjected to a Landau-Majorana-Stückelberg-Zener (LMSZ) ramp. We prove that LMSZ transitions of the two spin-qubits are possible…
Experimental demonstration of composite stimulated Raman adiabatic passage
Alexander Bruns, Genko T. Genov, Marcel Hain +2
We experimentally demonstrate composite stimulated Raman adiabatic passage (CSTIRAP), which combines the concepts of composite pulse sequences and adiabatic passage. The technique…
Arbitrarily accurate variable rotations on the Bloch sphere by composite pulse sequences
Boyan T. Torosov, Nikolay V. Vitanov
Composite pulse sequences, which produce arbitrary pre-defined rotations of a two-state system at an angle on the Bloch sphere, are presented. The composite sequences can conta…
Robust high-fidelity coherent control of two-state systems by detuning pulses
Boyan T. Torosov, Nikolay V. Vitanov
Coherent control of two-state systems is traditionally achieved by resonant pulses of specific Rabi frequency and duration, by adiabatic techniques using level crossings or delayed…
Arbitrarily accurate twin composite pulse sequences
Boyan T. Torosov, Nikolay V. Vitanov
We present three classes of symmetric broadband composite pulse sequences. The composite phases are given by analytic formulas (rational fractions of ) valid for any number of c…
Relations between the single-pass and double-pass transition probabilities in quantum systems with two and three states
Nikolay V. Vitanov
In the experimental determination of the population transfer efficiency between discrete states of a coherently driven quantum system it is often inconvenient to measure the popula…
