Mechanism of decoherence-free coupling between giant atoms
Physical Review Research, 2020 Giant atoms are a new paradigm of quantum optics going beyond the usual local coupling. Building on this, a new type of decoherence-free (DF) many-body Hamiltonians was shown in a broadband waveguide.

Temporal Response of Atoms Trapped in an Optical Dipole Trap: A Primer on Quantum Computing Speed
Atoms, 2023 An atom confined in an optical dipole trap is a promising candidate for a qubit. Analyzing the temporal response of such trapped atoms enables us to estimate the speed at which quantum computers operate.

Cavity atom optics and the `free atom laser' [PDF]
Optics Communications, 2000 The trap environment in which Bose-Einstein condensates are generated and/or stored strongly influences the way they interact with light. The situation is analogous to cavity QED in quantum optics, except that in the present case, one tailors the matter-wave mode density rather than the density of modes of the optical field.
