Spacecraft could soon carry sophisticated polarisation-sensitive optics, thanks to innovative design that miniaturises optical technology to a tiny fraction of its current size. These new components, based on metasurfaces, would be ideal for nanosatellites,...

Physicists have developed an ultra-compact quantum imager, based on an extremely sensitive high-resolution technique known as quantum ghost imaging. The new system uses a metasurface only 300 nanometres thick to generate entangled pairs of photons and makes...

One of quantum technology’s most powerful tools is interference, in which two or more identical particles interact in surprising ways – sometimes adding together, but sometimes subtracting from each other. This property can be used for quantum...

A key element for future quantum technology is a step closer with the unveiling of a tiny quantum light source, less than one hundredth the diameter of a hair thick. The device’s practical qualities will make it a valuable component for future...

Scientists have devised a way to reveal the superpowers of a crystal, with a mere flash of laser light. The superpowers in question, known as topological phases of light, include the ability to guide light along winding paths perfectly with no loss,...

An international team of researchers led by ANU is helping to build a safe data superhighway for the highly anticipated quantum internet, which promises a new era of artificial intelligence and ultra-secure communication. Associate Professor Andrey Sukhorukov...

An international team of researchers led by The Australian National University (ANU) has invented a tiny camera lens, which may lead to a device that links quantum computers to an optical fibre network. Quantum computers promise a new era in ultra-secure...
