Narrowband and passband composite rotational quantum gates
Hayk L. Gevorgyan
High-precision, robust quantum gates are essential components in quantum computation and information processing. In this study, we present an alternative perspective, exploring the…
Ultrabroadband, ultranarrowband and ultrapassband composite polarisation half-wave plates, ultrabroadband composite polarisation pi-rotators and on the quantum-classical analogy
Hayk L. Gevorgyan
Composite pulses, which produce ultrabroadband, ultranarrowband and ultrapassband -, -) rotations by on the Bloch-Poincaré sphere, are presented. The first class plays…
Deterministic generation of arbitrary ultrasmall excitation of quantum systems by composite pulse sequences
Hayk L. Gevorgyan, Nikolay V. Vitanov
In some applications of quantum control, it is necessary to produce very weak excitation of a quantum system. Such an example is presented by the concept of single-photon generatio…
Ultrahigh-fidelity composite quantum phase gates
Hayk L. Gevorgyan, Nikolay V. Vitanov
A number of composite pulse (CP) sequences for four basic quantum phase gates -- the Z, S, T and general phase gates -- are presented. The CP sequences contain up to 18 pulses and…
Ultrahigh-fidelity composite rotational quantum gates
Hayk Gevorgyan, Nikolay V. Vitanov
Composite pulse sequences, which produce arbitrary pre-defined rotations of a qubit on the Bloch sphere, are presented. The composite sequences contain up to 17 pulses and can comp…
