Nonlinear dissipation can combat linear loss
D. Mogilevtsev, A. Mikhalychev, V. S. Shchesnovich +1
We demonstrate that it is possible to compensate for effects of strong linear loss when generating non-classical states by engineered nonlinear dissipation. We show that it is alwa…
Time-efficient implementation of quantum search with qudits
S. S. Ivanov, H. S. Tonchev, N. V. Vitanov
We propose a simpler and more efficient scheme for the implementation of the multi-valued Grover's quantum search. The multi-valued search generalizes the original Grover's search…
Creation of arbitrary Dicke and NOON states of trapped-ion qubits by global addressing with composite pulses
Svetoslav S. Ivanov, Nikolay V. Vitanov, Natalia V. Korolkova
We propose a fast and efficient technique to create classes of highly entangled states of trapped ions, such as arbitrary Dicke states and superpositions of them, e.g. NOON states.…
Simulation of Jahn-Teller-Dicke Magnetic Structural Phase Transition with Trapped Ions
Peter A. Ivanov, Diego Porras, Svetoslav S. Ivanov +1
We study theoretically the collective Ee Jahn-Teller-Dicke distortion in a system of trapped ions. We focus in the limit of infinite range interactions in which an ensembl…
Quantum dynamics of the damped harmonic oscillator
T. G. Philbin
The quantum theory of the damped harmonic oscillator has been a subject of continual investigation since the 1930s. The obstacle to quantization created by the dissipation of energ…
Canonical quantization of the electromagnetic field interacting with a moving dielectric
S. A. R. Horsley
The electromagnetic field is canonically quantized in the presence of a linear, dispersive and dissipative medium that is in uniform motion. Specifically we calculate the change in…
