A superconducting on-chip microwave cavity for tunable hybrid systems with optically trapped Rydberg atoms [PDF]
arXivHybrid quantum systems are highly promising platforms for addressing important challenges of quantum information science and quantum sensing. Their implementation, however, is technologically non-trivial, since each component typically has unique experimental requirements.

Using graphene conductors to enhance the functionality of atom-chips [PDF]
, 2021 We show that the performance and functionality of atom-chips can be transformed by using graphene-based van der Waals heterostructures to overcome present limitations on the lifetime of the trapped atom cloud and on its proximity to the chip surface.

Intra-atomic frequency comb based photonic quantum memory using single-atom-cavity setup [PDF]
Phys. Rev. A 107, 012614 (2023), 2022 On-demand and efficient storage of photons is an essential element in quantum information processing and long-distance quantum communication. Most of the quantum memory protocols require bulk systems in order to store photons. However, with the advent of integrated photonic chip platforms for quantum information processing, on-chip quantum memories are

Two-dimensional array of microtraps with atomic shift register on a chip [PDF]
New J. Phys. 11 (2009) 023021, 2008 Arrays of trapped atoms are the ideal starting point for developing registers comprising large numbers of physical qubits for storing and processing quantum information. One very promising approach involves neutral atom traps produced on microfabricated devices known as atom chips, as almost arbitrary trap configurations can be realised in a robust and

Proposal of a free-space-to-chip pipeline for transporting single atoms [PDF]
, 2023 A free-space-to-chip pipeline is proposed to efficiently transport single atoms from a magneto-optical trap to an on-chip evanescent field trap. Due to the reflection of the dipole laser on the chip surface, the conventional conveyor belt approach can only transport atoms close to the chip surface but with a distance of about one wavelength, which ...

An on-chip optical lattice for cold atom experiments [PDF]
Optics Letters, Vol. 40, Issue 14, pp. 3368-3371 (2015), 2015 An atom-chip-based integrated optical lattice system for cold and ultracold atom applications is presented. The retro-reflection optics necessary for forming the lattice are bonded directly to the atom chip, enabling a compact and robust on-chip optical lattice system.

Phys. Rev. Lett. 84, 4749 (2000), 1999 Atoms can be trapped and guided using nano-fabricated wires on surfaces, achieving the scales required by quantum information proposals. These Atom Chips form the basis for robust and widespread applications of cold atoms ranging from atom optics to fundamental questions in mesoscopic physics, and possibly quantum information systems.

Cavity driven Rabi oscillations between Rydberg states of atoms trapped on a superconducting atom chip [PDF]
arXiv, 2021 Hybrid quantum systems involving cold atoms and microwave resonators can enable cavity-mediated infinite-range interactions between atomic spin systems and realize atomic quantum memories and transducers for microwave to optical conversion. To achieve strong coupling of atoms to on-chip microwave resonators, it was suggested to use atomic Rydberg ...

Integrated magneto-optical traps on a chip [PDF]
Optics Express, Vol. 17, Issue 16, pp. 14109-14114 (2009), 2009 We have integrated magneto-optical traps (MOTs) into an atom chip by etching pyramids into a silicon wafer. These have been used to trap atoms on the chip, directly from a room temperature vapor of rubidium. This new atom trapping method provides a simple way to integrate several atom sources on the same chip.

Coherent manipulation of Bose-Einstein condensates with state-dependent microwave potentials on an atom chip [PDF]
Nature Physics 5, 592 - 597 (2009), 2009 Entanglement-based technologies, such as quantum information processing, quantum simulations, and quantum-enhanced metrology, have the potential to revolutionise our way of computing and measuring and help clarifying the puzzling concept of entanglement itself.
