Random Numbers -- But Not By Chance

Researchers have devised a new kind of random number generator, for encrypted communications and other uses, that is cryptographically secure, inherently private and – most importantly – certified random by laws of physics.

In Search of Majorana

The long-awaited promise of topological quantum computing (TQC), a subject often discussed in the abstract as a possibility at some unspecified future date, suddenly seems imminent.

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.

What good are two photons if you can’t tell them apart? As it happens, they can be worth a great deal in ...

JQI Podcast Episode 1

A primer on the fundamental terms and concepts of quantum information science, with guest Dr. Carl Williams, Chief of the Atomic Physics Division at the National Institute of Standards and Technology. Topics include the bizarre condition called superposition, the nature of quantum bits ("qubits") and more.

Howard Students at NIST 2010

On March 11, 2010 a group from the Department of Physics & Astronomy at Howard University in Washington, DC visited the National Institute of Standards and Technology (NIST) for an introductory tour of several projects and program areas related to the Joint Quantum Institute (JQI).

Two Howard professors -- Dr. Prabhakar Misra and Dr. Silvina Gatica -- and 10 of ...

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.

The team, led by JQI Fellow ...

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.

Ultracold systems are those in which the atoms -- or, very recently, molecules -- under study are trapped at ...
