Quantum computers may be much easier to build than previously thought Physical Review Letters physorg, arXiv "Quantum computers should be much easier to build than previously thought, because they can still work with a large number of faulty or even missing components, according to a study published today in Physical Review Letters. This surprising discovery brings scientists one step closer to designing and building real-life quantum computing system—devices that could have enormous potential across a wide range of fields, from drug design, electronics, and even code-breaking."

Moving Towards Quantum Computing New York Times "Three major technologies have the potential to move from demonstration computers to practical, highly powerful machines. 'We’re at the stage of trying to develop these qubits in a way that would be like the integrated circuit that would allow you to make many of them at once,' said Rob Schoelkopf, a physicist who is leader of the Yale group. In the next few years you’ll see operations on more qubits, but only a handful. The good news is that while the number of qubits is increasing only slowly, the precision with which the researchers are able to control quantum interactions has increased a thousandfold."

Seth Lloyd—Quantum effects in Biological Systems MIT cbc.ca "Lloyd's biological research, funded by the US Defense Advanced Research Projects Agency, looks at how living things use quantum computation [...] Bird navigation, plant photosynthesis and the sense of smell all represent ways living things appear to exploit the oddities of quantum physics."

Google Workshop on Quantum Biology "Surprisingly robust quantum effects have been observed in warm biological systems. At the same time, quantum information technology has moved closer to physical realization. This Workshop on Quantum Biology will examine the significance of mesoscopic quantum coherence, tunneling and entanglement in biomolecular membranes, proteins, DNA and cytoskeleton, with particular attention to recently discovered megahertz ballistic conductance in microtubules. Potential utilization of biomolecular quantum information in regulation of cellular activities will be addressed, along with implications for disease and therapy as well as the future development of quantum computation and artificial intelligence." List of Speakers includes Alán Aspuru-Guzik (Harvard), Anirban Bandyopadhyay (Tsukuba), Stuart Hameroff (Tucson), Masoud Mohseni (MIT), Hartmut Neven (Google), Jiří Pokorný (Czech Republic), Elisabeth Rieper (Singapore), Mohan Sarova (Berkeley), Jack Tuszynski (Alberta), and Luca Turin (MIT)

"We believe it is timely to set out on a distinct quantum biology agenda. The burgeoning fields of nanotechnology, biotechnology, quantum technology, and quantum information processing are now strongly converging. As quantum engineering and nanotechnology meet, increasing use will be made of biological structures, or hybrids of biological and fabricated systems, for producing novel devices for information storage and processing, to create [novel sensors], and for other tasks. If experiments can shed further light on our understanding of decoherence in biomolecules, at scales where equilibrium thermodynamics no longer applies, this may provide the required foundation for greatly accelerating our progress in manmade quantum computers."

Are we living in a designer universe?  

MIT, Sussex "Creating a new universe would require a machine only slightly more powerful than the LHC—and there is every chance that our own universe may have been manufactured in this way." 
  – John Gribbin, Telegraph

"A basement universe possesses a fate independent of its parent: harnessing the zero-point energy to trigger inflation becomes a form of applied cosmological engineering. And if basement universes are a naturally occurring phenomenon, as suggested by inflationary cosmological models, the multiverse then takes on the characteristics of an evolutionary algorithm. Though the parent universe in any branching scenario need not have been of intelligent design, once a suitable set of cosmological constants is found through natural inflation, intelligent life could branch out from this point of origin, forming an expanding wavefront of intelligence and altering the evolution of the multiverse itself [...] 

Given that the conditions of the Drake equation are met, a potential explanation for the silence in our immediate neighborhood of the cosmos is that inter-universe panspermia supercedes local expansion. Vernor Vinge’s Singularity may not be only technological; it may be physical. The most powerful computer we can imagine would for all intensive purposes resemble a black hole."

Is reality even stranger than quantum mechanics tells us? 

"We know that quantum correlations can be stronger than classical—but why aren't quantum correlations even stronger? Either we are missing something very significant to define quantum theory, or these other theories are all around us too."
 – Caslav Brukner (New Scientist)

Any quantum state can be cloned in the presence of closed timelike curves  "The possible existence of closed timelike curves (CTCs) draws attention to fundamental questions about what is physically possible and what is not. An example is the "no cloning theorem" in quantum mechanics — which states that no physical means exists by which an unknown arbitrary quantum state can be reproduced, or copied perfectly. We show here that this theorem can be circumvented in the presence of closed timelike curves, allowing for the cloning of an unknown arbitrary quantum state. Since the "no cloning theorem" has played a central role in the development of quantum information science, it is clear that the existence of CTCs would radically change the rules for quantum information technology."

Molecular Simulation with Superconducting Qubits 

"Because Nature isn't classical, damnit, and if you want to make a simulation of nature, you'd better make it quantum mechanical. " —Richard Feynman 

Georgia, UCSB In arXiv:1008.0701, Pritchett, Martinis et al. introduce a protocol for efficient simulation of molecular dynamics using superconducting qubits. "Recent experimental progress suggests that quantum simulation will be one of the first practical applications of quantum computation. We have shown how quantum computers of only a few qubits can simulate arbitrary quantum systems accurately and quickly, even before they reach the regime of fault tolerant quantum computation."
