UChicago hasthis been able for the first time conduct an experiment shows the behavior of quantum materials in curved space. In their own words, “We are beginning to make our photons interact with each other. This opens up many possibilities, such as making crystalline or exotic quantum liquid states of light. We can then see how they respond to spatial curvature.”

CHICAGO–(ENEWSPF)–June 10, 2016. Light and matter are typically viewed as distinct entities that follow their own, unique rules. Matter has mass and typically exhibits interactions with other matter, while light is massless and does not interact with itself. Yet, wave-particle duality tells us that matter and light both act sometimes like particles, and sometimes like waves.

Harnessing the shared wave nature of light and matter, researchers at the University of Chicago, led by Jonathan Simon, the Neubauer Family Assistant Professor of Physics, have used light to explore some of the most intriguing questions in the quantum mechanics of materials. The topic encompasses complex and non-intuitive phenomena that are often difficult to explain in non-technical language, but which carry important implications to specialists in the field.

Elon Musk, the billionaire entrepreneur and founder of Space X, Tesla and Paypal, has told an interviewer there is only a “one in billions” chance that we’re not living in a computer simulation.

Speaking at San Francisco’s Code Conference this week, Musk said that he has had “so many simulation discussions it’s crazy”, and that it got to the point where “every conversation [he had] was the AI/simulation conversation”.

He also claimed that, if we’re not living in a simulation, we could be approaching the end of the world.

Google is to trying to combine the Adiabatic Quantum computing AQC method with the digital approach’s error-correction capabilities.

The Google team uses a row of nine solid-state qubits, fashioned from cross-shaped films of aluminium about 400 micrometres from tip to tip. These are deposited onto a sapphire surface. The researchers cool the aluminium to 0.02 degrees kelvin, turning the metal into a superconductor with no electrical resistance. Information can then be encoded into the qubits in their superconducting state.

The interactions between neighboring qubits are controlled by ‘logic gates’ that steer the qubits digitally into a state that encodes the solution to a problem. As a demonstration, the researchers instructed their array to simulate a row of magnetic atoms with coupled spin states — a problem thoroughly explored in condensed-matter physics. They could then look at the qubits to determine the lowest-energy collective state of the spins that the atoms represented.

Machines running on human energy? Yes, it can happen, according to Dan Nicolau, Jr. from the Department of Integrative Biology at the University of California. Nicolau and his colleagues successfully completed a proof-of-concept study of a book-sized computer that runs on adenosine triphosphate (ATP), a biochemical that releases energy in cells and aids in energy transfer.

The study results published in the Proceedings of the National Academy of Sciences (PNAS), describe the combination of geometrical modeling and engineering as well as nanotechnology to create circuitry that uses 1.5 × 1.5 cm in area and the naturally occurring protein to operate.

A More Sustainable Option

Other than the mere presence of a human energy source in a machine, an astounding aspect of the device is how, as opposed to electrical energy that produces heat, the biological agent powering this new computer enables it to remain cool and energy efficient, making it more sustainable.

The QUTIS research group (www.qutisgroup.com) of the University of the Basque Country (UPV/EHU) and Google’s quantum computation team have collaborated on a pioneering experiment that universally digitizes analogue quantum computation on a superconducting chip. This breakthrough was made at Google’s labs in Santa Barbara (California) and has been published in the prestigious journal Nature.
