What Has to Happen for Quantum Computing to Hit Mainstream? | If you stretch the timeline of quantum computing onto the timeline of IBM computers, we’re somewhere between the vacuum-tube-powered machines of the 1940s and the models built on transistors, integrated circuits, and silicon of the 1960s. And we’re much closer to the former.  Source: DataCenter Knowledge .   What Has to Happen for Quantum Computing to Hit Mainstream?

Layered Graphene with a Twist Displays Unique Quantum Confinement in 2-D | Scientists studying two different configurations of bilayer graphene—the two-dimensional (2-D), atom-thin form of carbon—have detected electronic and optical interlayer resonances. In these resonant states, electrons bounce back and forth between the two atomic planes in the 2-D interface at the same frequency. By characterizing these states, they found that twisting one of the graphene layers by 30 degrees relative to the other, instead of stacking the layers directly on top of each other, shifts the resonance to a lower energy. From this result, just published in Physical Review Letters, they deduced that the distance between the two layers increased significantly in the twisted configuration, compared to the stacked one. When this distance changes, so do the interlayer interactions, influencing how electrons move in the bilayer system. An understanding of this electron motion could inform the design of future quantum technologies for more powerful computing and more secure communication.   Source: Brookhaven.   Layered Graphene with a Twist Displays Unique Quantum Confinement in 2-D…

How Big Can the Quantum World Be? Physicists Probe the Limits. | Two teams of researchers, in Austria and Switzerland, have independently succeeded in freezing such minuscule nanoparticles, just 100 to 140 nanometers across, almost entirely into their lowest-energy quantum state, giving them effectively a temperature just a few millionths of a degree above absolute zero — and fixing them in place with unearthly precision.  Source: Quantamagazine.   How Big Can the Quantum World Be?

China gains the quantum advantage | Chinese scientists recently claimed they had gained the global edge in quantum computing over Google with a device that can complete in 70 minutes a task that would take the world’s fastest non-quantum supercomputer more than eight years.  Source: Bangkok Post.   China gains the quantum advantage…

Can a piece of sticky tape stop computer hackers in their tracks? | Researchers from the University of Technology Sydney (UTS) and TMOS, an Australian Research Council Centre of Excellence, have taken the fight to online hackers with a giant leap towards realizing affordable, accessible quantum communications, a technology that would effectively prevent the decryption of online activity. Everything from private social media messaging to banking could become more secure due to new technology created with a humble piece of adhesive tape.  Source: EurekAlert!.   Can a piece of sticky tape stop computer hackers in their tracks?
