Manufacturing Bits: April 19


Hot videos The University of Minnesota has recorded videos that show how heat travels through materials, a move that could give researchers insight into the behavior of atoms and other structures. It could also pave the way towards the development of more efficient materials for use in electronics and other applications. In the lab, researchers used FEI’s transmission electron microsc... » read more

Power/Performance Bits: March 22


Superconducting memory A group of scientists from the Moscow Institute of Physics and Technology and the Moscow State University developed a fundamentally new type of memory cell based on superconductors, which they believe will be able to work hundreds of times faster than memory devices commonly used today. The basic memory cells are based on quantum effects in "sandwiches" of supercond... » read more

System Bits: March 3


Observing antiferromagnetic order in ultracold atoms Rice University researchers have simulated superconducting materials and made headway on a problem that’s vexed physicists for nearly three decades using ultracold atoms as a stand-in for electrons. The research team, led by Rice, included researchers from Ohio State University, Universidade Federal do Rio de Janeiro, University of Cal... » read more

System Bits: Oct. 21


Simplified superconducting circuits Computer chips with superconducting circuits, which means they have no electrical resistance, are said to be 50 to 100 times as energy-efficient as today’s technology. Superconducting chips are also said to have greater processing power: Superconducting circuits that use so-called Josephson junctions have been clocked at 770 gigahertz, or 500 times the spe... » read more

Not All Qubits Are Small


While diamond nitrogen-vacancy centers offer one attractive implementation of quantum qubits, many other systems have been proposed. In theory, at least, any system with clearly identifiable quantum states can serve the purpose. The challenge lies in finding a system in which those states can be manipulated and measured by external forces and can be fabricated in large enough numbers for practi... » read more

Power/Performance Bits: Jan. 21


Spinning towards superconduction With spintronics widely believed to be the basis of a future revolution in computing, researchers at the University of Cambridge are reporting what they said is the first evidence that superconductors could be used as an energy-efficient source for so-called “spin-based” devices, which are already starting to appear in electronic devices. Spintronic devi... » read more
