Intel Accelerates Its Quantum Computing Efforts With 17-Qubit Chip
Posted by Klaus Baldauf in categories: computing, information science, quantum physics
Intel says it is shipping an experimental quantum computing chip to research partners in The Netherlands today. The company hopes to demonstrate that its packaging and integration skills give it an edge in the race to produce practical quantum computers.
The chip contains 17 superconducting qubits—the quantum computer’s fundamental component. According to Jim Clarke, Intel’s director of quantum hardware, the company chose 17 qubits because it’s the minimum needed to perform surface code error correction, an algorithm thought to be necessary to scaling up quantum computers to useful sizes.
Intel’s research partners, at the TU Delft and TNO research center Qutech, will be testing the individual qubits’ abilities as well as performing surface code error correction and other algorithms.

This Overlooked Theory Could Be The Missing Piece That Explains How The EM Drive Works
Posted by Andreas Matt in categories: quantum physics, space travel
Ever since the EM drive first made headlines, science lovers have puzzled over how the propulsion system seems to produce thrust, despite the fact it’s ‘impossible’ according to one of the most fundamental laws of physics — Newton’s third law of motion.
Now a team of physicists have put forward an alternative explanation — it turns out the EM drive could actually work without breaking any scientific laws, if we factor in a weird and often overlooked idea in quantum physics — pilot wave theory.
For those who need a refresher, the crux of the problem here is that the EM, or electromagnetic, drive appears to produce thrust without any fuel or propellant.

Microsoft Unveils Programming Language for Quantum Computing
Posted by Jeremy Lichtman in categories: computing, quantum physics
At its Ignite developer conference yesterday, Microsoft announced that it has developed a new programming language designed to not only run on current computers but on the most advanced machines of the future: quantum computers. Ignite is running from Sept. 25–29 in Orlando.
Like many other of the world’s largest tech companies, Microsoft has been working to develop quantum computers that could handle massively complex problems in minutes or seconds. Unlike today’s conventional devices that use the digital bits “0” and “1,” quantum computers use qubits that can act as 0s, 1s or both simultaneously.
Microsoft said its new quantum computing language, which has yet to be named, is “deeply integrated” into its Visual Basic development environment and does many of the things other standard programming languages do. However, it is specifically designed to allow programmers to create apps that will eventually run on true quantum computers.

A Rare Element From The Edge of The Periodic Table Is Breaking Quantum Mechanics
Posted by Shailesh Prasad in categories: chemistry, quantum physics
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 can supercharge current antibiotics
Posted by Shailesh Prasad in categories: nanotechnology, quantum physics
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.

Fundamental Particles & Forces: What do we know?
Posted by Philip Raymond in categories: chemistry, general relativity, particle physics, physics, quantum physics, science
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]

Are Space, Time, And Gravity All Just Illusions?
Posted by Ian Hale in categories: cosmology, information science, particle physics, quantum physics
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.”
