April 18, 2011 — Researchers have achieved plasmonic properties in the semiconductor nanocrystals known as quantum dots. Until now, plasmonic properties, which hold promise for superfast computers and ultrapowerful ... > full story -
Quantum Mapmakers Complete First Voyage Through Spin Liquid
April 5, 2011 — Scientists have mapped a state of matter called 'quantum spin liquid', whose existence was proposed in the 1970s but which has only been observed ... > full story -
World First: Calculations With 14 Quantum Bits
April 1, 2011 — Quantum physicists have now achieved controlled entanglement of 14 quantum bits (qubits) and, thus, realized the largest quantum register that has ever been produced. With this experiment the ... > full story -
First Non-Trivial Atom Circuit: Progress Toward an Atom SQUID
March 31, 2011 — Researchers have created the first non-trivial "atom circuit," a donut-shaped loop of ultracold gas atoms circulating in a current analogous to a ring of electrons in a superconducting ... > full story -
Templated Growth Technique Produces Graphene Nanoribbons With Metallic Properties
March 21, 2011 — A new "templated growth" technique for fabricating nanoribbons of epitaxial graphene has produced structures just 15 to 40 nanometers wide that conduct current with almost no resistance. These ... > full story -
Quantum Pen for Single Atoms Is a Big Step Toward Large-Scale Quantum Computing
March 17, 2011 — Physicists have succeeded in manipulating atoms individually in a lattice of light and in arranging them in arbitrary patterns. These results are an important step towards large-scale quantum ... > full story -
Quantum Cryptography? Physicists Move Closer to Efficient Single-Photon Sources
March 16, 2011 — A team of physicists has taken a giant step toward realizing efficient single-photon sources, which are expected to enable much-coveted completely secure optical communications, also known as ... > full story
