Google reveals blueprint for quantum supremacy.
The ability of quantum machines to outperform classical computers is called quantum supremacy. Now Google says it has this goal firmly in its sights.
There’s a lot we don’t know about the actinides. On the periodic table, this series of heavy, radioactive elements hangs at the bottom, and includes a host of mysterious substances that don’t naturally occur on Earth.
Among this cast of unknowns, berkelium looks to be even stranger than we realised. New experiments with this incredibly rare synthetic element have shown that its electrons don’t behave the way they should, defying quantum mechanics.
“It’s almost like being in an alternate universe because you’re seeing chemistry you simply don’t see in everyday elements,” says chemist Thomas Albrecht-Schmitt from Florida State University.
Light-activated nanoparticles, also known as quantum dots, can provide a crucial boost in effectiveness for antibiotic treatments used to combat drug-resistant superbugs such as E. coli and Salmonella, new University of Colorado Boulder research shows.
Multi-drug resistant pathogens, which evolve their defenses faster than new antibiotic treatments can be developed to treat them, cost the United States an estimated $20 billion in direct healthcare costs and an additional $35 billion in lost productivity in 2013.
CU Boulder researchers, however, were able to re-potentiate existing antibiotics for certain clinical isolate infections by introducing nano-engineered quantum dots, which can be deployed selectively and activated or de-activated using specific wavelengths of light.

Do you remember all the hoopla last year when the Higgs Boson was confirmed by physicists at the Large Hadron Collider? That’s the one called the ‘God particle’, because it was touted as helping to resolve the forces of nature into one elegant theory. Well—Not so fast, bucko!…
First, some credit where credit is due: The LHC is a 27-kilometer ring of superconducting magnets interspersed by accelerators that boost the energy of the particles as they whip around and smash into each other. For physicists—and anyone who seeks a deeper understanding of what goes into everything—it certainly inspires awe.
Existence of the Higgs Boson (aka, The God Particle) was predicted. Physicists were fairly certain that it would be observed. But its discovery is a ‘worst case’ scenario for the Standard Model of particle physics. It points to shortcomings in our ability to model and predict things. Chemists have long had a master blueprint of atoms in the Periodic Table. It charts all the elements in their basic states. But, physicists are a long way from building something analogous. That’s because we know a lot more about atomic elements than the fundamental building blocks of matter and energy. [continue below image]

Pioneered by Erik Verlinde, the idea is that gravity emerges from a more fundamental phenomenon in the Universe, and that phenomenon is entropy.
“Sound waves emerge from molecular interactions; atoms emerge from quarks, gluons and electrons and the strong and electromagnetic interactions; planetary systems emerge from gravitation in General Relativity. But in the idea of entropic gravity — as well as some other scenarios (like qbits) — gravitation or even space and time themselves might emerge from other entities in a similar fashion. There are well-known, close relationships between the equations that govern thermodynamics and the ones that govern gravitation. It’s known that the laws of thermodynamics emerge from the more fundamental field of statistical mechanics, but is there something out there more fundamental from which gravity emerges? That’s the idea of entropic gravity.”

These recent advances in hardware have highlighted a chicken-and-egg problem: what use will quantum machines be if there is no software to run on them? That accounts for this year’s race to win over developers, who will need to learn a completely new programming approach in preparation for the future machines.
Problem is to persuade developers to make programs for machines that don’t yet exist.
When one of the first personal computers, the Altair 8800 came along in 1976, Microsoft was ready with a programming language, Altair BASIC. It wants to be equally prepared when quantum computers go mainstream, so it has unveiled a new programming language and other tools for the futuristic tech at its Ignite conference. You’ll still need to understand Qubits and other weird concepts, but by integrating traditional languages like C# and Python, Microsoft will make it easier to do mainstream computing on the complex machines.
Quantum computing is famously difficult to grasp — even IBM’s “Beginner’s Guide” is laughingly opaque. In discussing Microsoft’s new initiatives, Bill Gates called the physics “hieroglyphics,” and when asked if he could describe it in one sentence, Satya Nadella said “I don’t think so. I wish I could.”

President Chunli Bai of the Chinese Academy of Sciences in Beijing had a meeting yesterday with President Anton Zeilinger of the Austria Academy of Sciences in Vienna.
Although 7,400 kilometres (4,600 miles) apart, they were certain no uninvited guests were eavesdropping thanks to the fact their video call was encrypted. Quantum style.
Just a few months ago, China was in the news for a landmark achievement in quantum communication, using a satellite called Micius to transmit entangled photons over a record distance.
