Jeremy O’Brien visited Google LA to deliver a talk: “Quantum Technologies.” This talk took place on April 1, 2014.


The impact of quantum technology will be profound and far-reaching: secure communication networks for consumers, corporations and government; precision sensors for biomedical technology and environmental monitoring; quantum simulators for the design of new materials, pharmaceuticals and clean energy devices; and ultra-powerful quantum computers for addressing otherwise impossibly large datasets for machine learning-artificial intelligence applications. However, engineering quantum systems and controlling them is an immense technological challenge: they are inherently fragile; and information extracted from a quantum system necessarily disturbs the system itself. Despite these challenges a small number of quantum technologies are now commercially available. Delivering the full promise of these technologies will require a concerted quantum engineering effort jointly between academia and industry. We will describe our progress in the Centre for Quantum Photonics to delivering this promise using an integrated quantum photonics platform—generating, manipulating and interacting single particles of light (photons) in waveguide circuits on silicon chips.


Jeremy O’Brien is professor of physics and electrical engineering and director of the Centre for Quantum Photonics (CQP). He received his Ph.D. in physics from the University of New South Wales in 2002 for experimental work on correlated and confined electrons in organic conductors, superconductors and semiconductor nanostructures, as well as progress towards the fabrication of a phosphorus in silicon quantum computer. As a research fellow at the University of Queensland (2001-2006) he worked on quantum optics and quantum information science with single photons. CQP’s efforts are focused on the fundamental and applied quantum mechanics at the heart of quantum information science and technology, ranging from prototypes for scalable quantum computing to generalised quantum measurements, quantum control, and quantum metrology.

The Radiology Detective: Utilizing Clues Within High-Tech Imaging Exams to Solve Medical Mysteries

Cone Beam Radiography

Since Roentgen discovered x-rays in 1896, radiologists have had access to extremely powerful tools used to peer into a patient. Although x-rays are still used today, computers and other technological advancements have contributed to the development of extremely sophisticated medical imaging devices, such as CT, ultrasound, MR and PET scans. Dr. Richard Breiman, UCSF Professor of Radiology, explains how several medical imaging examinations work. He discusses how they are interpreted, as well as the beneficial clues they provide, which may help solve medical mysteries and contribute to patient management.

A Colorful Lunar Eclipse

Science at NASA

Mark your calendar: On Oct. 8th, the Moon will pass through the shadow of Earth for a total lunar eclipse. Sky watchers in the USA will see the Moon turn a beautiful shade of celestial red and maybe turquoise, too.

Stunning Timelapse of the Earth From Space

The Mysterious Holes in the Atmosphere on Venus

NASA Goddard

The European Space Agency’s Venus Express mission saw something it could not explain. It appeared that there were holes on the nightside of Venus’ ionosphere. Researchers at NASA’s Goddard Space Flight Center investigated these mysterious holes, and found evidence that the sun’s magnetic field lines may be penetrating through the planet.

Soft Robotic Exosuit

Re-engineering Sight

Brain Craft

These cool glasses give new hope for visually impaired people to see again.

Exoplanet Q & Alien

NASA Jet Propulsion Laboratory

In this inaugural edition of Exoplanet Q & Alien, JPL’s Josh Rodriguez explains some of the techniques used for direct imaging of “exoplanets” — planets outside of our solar system.

GeForce GTX 980 & 970 Product Video


Discover the GeForce GTX 980 and 970—the world’s most advanced graphics cards. Powered by NVIDIA Maxwell architecture and inspired by light, these GPUs include incredible performance and advanced technologies such as MFAA, DSR, and VXGI to deliver a truly elite gaming experience.

These GPUs are based on new Maxwell architecture and deliver performance at an incredible 165 watts, which means your PC will be whisper quiet. New technologies are:

  1. Multi-Frame Sampled Anti-Aliasing (MFAA): A simple idea where by looking at multiple frames over time we can combine them and generate an image with the same quality as MSAA, but we can do that at a fraction of the performance cost of traditional multisampling.
  2. Dynamic Super Resolution (DSR): Allows you to have a 4K experience on a 19×10 monitor.
  3. Voxel Global Illumination (VXGI): Technology allows to simulate light inside the game in real time.
