Quantum tunneling results in record transistor performance

(PhysOrg.com) -- Controlling power consumption in mobile devices and large scale data centers is a pressing concern for the computer chip industry. Researchers from Penn State and epitaxial wafer maker IQE have created a ...

Using nanophotonics to reshape on-chip computer data transmission

A team at Stanford's School of Engineering has demonstrated an ultrafast nanoscale light emitting diode (LED) that is orders of magnitude lower in power consumption than today's laser-based systems and able to transmit data ...

Nvidia Tegra 3 quad-core chip stokes tablet wars

(PhysOrg.com) -- Nvidia has launched its Tegra 3, the quad-core chip designed for mobile devices. Tech and investor blogs were busy yesterday assessing what this means for upcoming tablets and smartphones as to performance ...

Physicists move one step closer to quantum computer

Rice University physicists have created a tiny "electron superhighway" that could one day be useful for building a quantum computer, a new type of computer that will use quantum particles in place of the digital transistors ...

Hints of universal behavior seen in exotic three-atom states

A novel type of inter-particle binding predicted in 1970 and observed for the first time in 2006, is forming the basis for an intriguing kind of ultracold quantum chemistry. Chilled to nano-kelvin temperatures, cesium atoms ...

Nvidia says Kal-El chip will have five cores

(PhysOrg.com) -- Nvidia says its upcoming Kal-El chip (Tegra 3) will have five cores, not four. The news appeared this week when the Santa Clara company announced a white paper describing the architecture of this system-on-a-chip ...

Research reveals vital insight into spintronics

(PhysOrg.com) -- Progress in electronics has relied heavily on reducing the size of the transistor to create small, powerful computers. Now spintronics, hailed as the successor to the transistor, looks set to transform the ...
