The AQUID effective dynamics are those of a qubit, so the device may provide a new physical implementation for quantum computation with reduced decoherence. In order to achieve this aim, we examine the dependence of the qubit energy gap on the bosonic density, the interaction strength, and the barrier depth, and we show how the superposition between current states appears in the momentum distribution time-of-flight images.

These are the basic elements that are needed to engineer arbitrarily complex matter wave circuitry. The Doppler effect, the shift in the frequency of sound due to motion, is present in both classical gases and quantum superfluids.
How To Build An Atomtronic Computer - MIT Technology Review
And unlike semiconductor lattices, optical lattices can be made more or less perfectly. The deadline for submissions is 15 September From Wikipedia, the free encyclopedia. We demonstrate that selective qubit addressing with resonant microwaves can be programmed by controlling static and radio-frequency currents in microfabricated conductors. Domotics Nanorobotics Powered exoskeleton Self-reconfiguring modular robot Swarm robotics Uncrewed vehicle.
Families of solitary waves bifurcate from the planar dark soliton and include the solitonic vortex, the vortex ring and more complex structures of intersecting vortex lines known collectively as Chladni solitons.
Its publishing company, IOP Publishing, is a world leader in professional scientific communications. We present the properties of the ground state and low-energy excitations of Bose—Hubbard chains with a geometry that varies from open to closed and with a atomtronucs twisted link.

The strength, the sign and the direction of the induced dipole moment is therefore fully tunable. The Institute of Physics IOP is a leading scientific society promoting physics and bringing physicists together for the benefit of all.
The transport dynamics are shown to depend strongly on a feedback parameter determined by the relative heights of the two barriers forming the gate region.
Perhaps they could do with some help to get the first atomtronic devices up and running. The idea is to manipulate neutral atoms using lasers in a way that mimics the behaviour of electrons in wires, transistors and logic gates. Like Europe, Borneo hosted Stone Age cave artists. The resonant frequencies depend upon the particular configuration of the barrier, but are commensurate with the orbital frequency of a Bogoliubov sound wave traveling around the ring. Ideally, this issue will receive and accept 20—30 contributions, covering both theoretical and experimental works.
Atomtronics is a young, small and mostly theoretical field based on the idea that atoms in unusual quantum states of matter may provide an alternative to the tried-and-true electron for making useful devices. The gas is subject to a density dependent gauge potential, hence governed by an interacting gauge theory, which stems from a collisionally induced detuning between the incident laser frequency and the atomic energy levels.
Corrections to the ideal Sagnac phase are investigated for both cases. A potent fish oil drug may protect high-risk patients against heart attacks. Atomtronnics also give rise to novel solutions with a nonzero circulation.
Physicists have developed a new type of circuit that is little more than a puff of gas dancing in atomtfonics beams. Bringing Quantum Computing to Everyone, Everywhere atomtornics In the Year of Light, the goal of this focus issue is to survey the state of the art of Atomtronics-enabled Quantum Atomtfonics and, at the same time, to trigger new concepts and applications for the field.
