Controlling Trapped Atoms with RF

Scientists use radio-frequency radiation as a "tuning knob" for adjusting attraction or repulsion among atoms. Read More

Benefits of Frustration

A new class of interactions can control spin-spin coupling among trapped ions -- including cases of magnetic frustration in three ions -- to produce custom-tunable entangling gates. Read More

Diamond Sparkle as Quantum Information

Controlling the behavior of a crystal 'defect' called an NV center may lead to drastic improvements in magnetometers ... or maybe the qubit of the future. Read More

Controlling Qubits One at a Time

JQI researchers have demonstrated a way to address a single qubit in an optical lattice without disturbing an adjacent qubit only half a micrometer away. Read More

The Quantum Wire

Quantum gas microscope offers glimpse of quirky ultracold atoms
EurekAlert -- Physicists have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in bizarre ways.
Creating a six-qubit cluster state
PhysOrg -- A team of researchers believes their new results represent the first time a six-qubit linear cluster state, built using a two-photon triple entangled state, has been experimentally demonstrated.
Caught at the finishing line
Nature -- News & Views: Quantum systems habitually leak information, limiting their usefulness for practical applications. By optimally reversing the leak, this information loss has been reduced to a trickle in the solid state. [PDF]
Quantum computers could tackle enormous linear equations
Science News -- A new algorithm may give quantum computers a new, practical job: quickly solving monster linear equations. Such problems are at the heart of complex processes such as image and video processing, genetic analyses and even Internet traffic control.
Weird "Particles" Spotted in Hot New Material
ScienceNOW -- A team of physicists has taken a key step in fulfilling graphene’s promise as a hotbed of exotic physics by showing that the electrons within it can team up to behave like particles with a fraction of the electron's charge.
Entanglement on Demand
Nature News -- Superconductors could be a rich source of electrons for quantum networks.
How Perfect Can Graphene Be?
PhysOrg -- Physicists have investigated the purest graphene to date, and have found that the material possesses unprecedented high electronic quality.
Passage through chaos
Nature -- News & Views: A quantum system can undergo tunneling even without a barrier to tunnel through. The latest experiments visualize this process in exquisite detail, completely reconstructing the state of the evolving system. [PDF]
