Monitoring currents in cold-atom circuits
S. Safaei, L. -C. Kwek, R. Dumke +1
Complex circuits of cold atoms can be exploited to devise new protocols for the diagnostics of cold-atoms systems. Specifically, we study the quench dynamics of a condensate confin…
Two-dimensional network of atomtronic qubits
Shabnam Safaei, Benoît Grémaud, Rainer Dumke +3
Through a combination of laser beams, we engineer a two-dimensional optical lattice of Mexican hat potentials able to host atoms in its ring-shaped wells. When tunneling can be ign…
Triangular and Honeycomb Lattices of Cold Atoms in Optical Cavities
Shabnam Safaei, Christian Miniatura, Benoît Grémaud
We consider a two-dimensional homogeneous ensemble of cold bosonic atoms loaded inside two optical cavities and pumped by a far-detuned external laser field. We examine the conditi…
Optimization of Junction and Bias Parameters in readout of Phase Qubit
Hesam Zandi, Shabnam Safaei, Sina Khorasani +1
The exact numerical solution of the nonlinear Ginzburg-Landau equation for Josephson junctions is obtained, from which the nontrivial current density and effective potential of the…
Optimized single-qubit gates for Josephson phase qubits
Shabnam Safaei, Simone Montangero, Fabio Taddei +1
In a Josephson phase qubit the coherent manipulations of the computational states are achieved by modulating an applied ac current, typically in the microwave range. In this work w…
Optimized Cooper pair pumps
Shabnam Safaei, Simone Montangero, Fabio Taddei +1
In adiabatic Cooper pair pumps, operated by means of gate voltage modulation only, the quantization of the pumped charge during a cycle is limited due to the quantum coherence of t…
