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.

Controlling Trapped Atoms with RF

Investigating mysterious data in ultracold gases of rubidium atoms, scientists at the Joint Quantum Institute and collaborators have found that properly tuned radio-frequency waves can influence how much the atoms attract or repel one another, opening up new ways to control their interactions.

Benefits of Frustration

Scientists have demonstrated a new way to control quantum interactions that makes it possible to fine-tune the way in which the magnetic properties of trapped atoms couple to, and are "entangled" with, those of their neighbors -- a development with potentially important applications in quantum computing and condensed-matter simulations.

Motion Damping Explained

Theorists have provided an explanation for experimental quantum-mechanical findings that have puzzled researchers for years, opening new possibilities for studying and manipulating ultracold atoms in lattices.

Opening A Remote Quantum Gate

Opening a Remote Quantum Gate

Physicists have created and demonstrated a remote “quantum gate” – a key component for long-range quantum information transfer and an essential element of one plan for a quantum computer – by carefully manipulating the atomic states of two separately trapped ions.

Controlling Bits

Controlling Individual Bits

Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised* a viable way to manipulate a single “bit” in a quantum processor without disturbing the information stored in its neighbors.

Improving Josephson Junction Qubits

An interdisciplinary research collaboration, centered at the University of Maryland (UMD) at College Park, has been awarded $2.8 million from the Intelligence Advanced Research Projects Activity (IARPA) through the Army Research Office (ARO) to devise, fabricate, study and test a new kind of key component for quantum computing.

New System for Detection of Single Atoms

Scientists have devised a new technique for real-time detection of freely moving individual neutral atoms that is more than 99.7% accurate and sensitive enough to discern the arrival of a single atom in less than one-millionth of a second, about 20 times faster than the best previous methods.

JQI Wins Two MURI Awards for FY2009

Joint Quantum Institute researchers have won two highly sought-after MURI awards from the U.S. Department of Defense out of 41 projects selected for funding in a nationwide competition. The Pentagon will provide a total of $260 million over five years to the FY2009 awardees in the Multidisciplinary University Research Initiative (MURI) program, with specific allocations to be determined in subsequent discussions.
