Tunable broadband polarization retarders
Hristina S. Hristova, Svetoslav S. Ivanov, Nikolay V. Vitanov +1
We theoretically propose a type of tunable polarization retarder, which is composed of sequences of half-wave and quarter-wave polarization retarders, allowing operation at broad s…
High-fidelity quantum control by polychromatic pulse trains
Svetoslav S. Ivanov, Boyan T. Torosov, Nikolay V. Vitanov
We introduce a quantum control technique using polychromatic pulse sequences (PPS), consisting of pulses with different carrier frequencies, i.e. different detunings with respect t…
Arbitrary polarization control by magnetic field variation
Elena Stoyanova, Svetoslav Ivanov, Andon Rangelov
We propose a universal scheme for the construction of a device for arbitrary to arbitrary polarization transformation, which consists of two quarter-wave plates and two Faraday rot…
Narrowband and passband composite pulses for variable rotations
Boyan T. Torosov, Svetoslav S. Ivanov, Nikolay V. Vitanov
We develop a systematic approach to derive narrowband (NB) and passband (PB) composite sequences which can produce any pre-selected transition probability with any desired accuracy…
Versatile microwave-driven trapped ion spin system for quantum information processing
Ch. Piltz, Th. Sriarunothai, S. Ivanov +2
Using trapped atomic ions we demonstrate a tailored and versatile effective spin-system suitable for quantum simulations and universal quantum computation. By simply applying micro…
Highly efficient broadband polarization retarders and tunable polarization filters made of composite stacks of ordinary wave plates
Emiliya St. Dimova, Svetoslav S. Ivanov, George St. Popkirov +1
By using the formal analogy between the evolution of the state vector in quantum mechanics and the Jones vector in polarization optics, we construct and demonstrate experimentally…
