Interfering with Quantum Dots

Scientists at the Joint Quantum Institute have devised a new method that could be used to generate multiple pairs of “indistinguishable” photons – near-identical individual quanta of light – by fine-tuning the output from two separate quantum dots.

Entanglement with Frequency Combs

For the first time, scientists have employed a powerful technique of laser physics – the “optical frequency comb” – to entangle two trapped atoms.* This form of control is a promising candidate for use as a logic gate for quantum computing and information-processing, and offers substantial operational advantages over other methods of laser-generated entanglement.

Seeing the Quantum in Chemistry

Physicists at JILA have for the first time observed chemical reactions near absolute zero, demonstrating that chemistry is possible at ultralow temperatures and that reaction rates can be controlled using quantum mechanics, the peculiar rules of submicroscopic physics.

Modeling Ultracold Molecular Collisions

Two theorists have devised a simple, widely applicable model1 for characterizing the ways in which ultracold molecules interact under a range of conditions, improving researchers' ability to control, measure and understand phenomena in one of the most exciting fields of modern physics.

Soliton in Ultracold Gases

Solitary waves that run a long distance without losing their shape or dying out are a special class of waves called solitons. These everlasting waves are exotic enough, but JQI theoreticians and colleagues in India and the George Mason University now believe that there may be a new kind of soliton that’s even more special.

Synthetic Magnetism Achieved by Optical Methods in Ultracold Atoms

For the first time, physicists have used laser light to create "synthetic magnetism," an exotic condition in which neutral atoms suddenly begin to behave as if they were charged particles interacting with a magnetic field -- even though no such field is present and the atoms have no charge.

Entangled Photons from Quantum Dots

To exploit the quantum world to the fullest, a key commodity is entanglement—the spooky, distance-defying link that can form between objects such as atoms even when they are completely shielded from one another.
