Nonlinear nanoelectromechanics of a movable Cooper-pair box
S. Park, A. Patra, L. Y. Gorelik +3
We theoretically study the dynamics of a movable Cooper-pair box coupled to a normal-metal pillar using a semiclassical approach. We analyze the dynamical stability induced by the…
Adiabatic self-vibrations of a movable Cooper-pair box generated by inelastic Andreev tunneling
Sunghun Park, Anton V. Parafilo, Leonid Y. Gorelik +1
Self-sustained oscillators produce stable periodic motion robust to dissipation. Such motion is usually achieved by work fed back into the oscillator, but its performance is often…
Creation of two-dimensional circular motion of charge qubit
Leonid Y. Gorelik, Sergei I. Kulinich, Robert I. Shekhter +1
We suggest a nanoelectromechanical setup which generates a particular type of motion - the circular motion of mesoscopic superconducting grain, where motion is described by entangl…
Nanomechanical ancilla qubits generator for error correction algorithms in quantum computation
Danko RadiÄ, Leonid Y. Gorelik, Sergei I. Kulinich +1
We suggest a nanoelectromechanical setup that generates properly entangled ancillary ("ancilla") qubits for error correction algorithms in quantum computing, demonstrated as an enc…
