Built in quality control to make quantum tech more reliable

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...

Teleportation fidelity the big winner in the quantum lottery

Running your quantum system as a lottery turns out to be a way to improve the transmission of data via quantum teleportation. Researchers at the Research School of Physics used a probabilistic twist to develop a new transmission protocol that set a new record...

Physicists more certain than Heisenberg

In a string of accurate quantum experiments, physicists have violated Heisenberg’s Uncertainty Principle – one of the icons of quantum weirdness, with its counter-intuitive statement that all measurements are essentially fuzzy and cannot be improved...

Noise cancelling glasses for quantum sensors

A simple piece of carefully chosen glass could be the key to cancelling out noise in extremely precise quantum sensors. Dr Jiayi Qin, from ANU Quantum Optics Group, said this simple solution to photothermal noise – disruptions to experiments due to heat...

ANU random numbers go global

ANU launches world's most popular online random number generator powering research simulations and gaming, and inspiring artists' works and children's names on  Amazon Web Services' marketplace.  The Australian National University's (ANU) ANU Quantum...

Reducing noise of quantum light below the sound of silence

An international team of researchers has developed a technology that manipulates quantum states of light at noise levels that are quieter than the sound of silence. The technology is an important development towards quantum computers, which could solve...

ANU research set to shake-up space missions

A new study from The Australian National University (ANU) has found a number of 2D materials can not only withstand being sent into space, but potentially thrive in the harsh conditions. It could influence the type of materials used to build everything...

AI changing the way ANU scientists carry out experiments

There’s plenty of speculation about what artificial intelligence, or AI, will look like in the future, but researchers from The Australian National University (ANU) are already harnessing its power. The group from the ANU Department of Quantum...

Boost for ANU space and quantum technology

The Australian National University (ANU) has welcomed ACT Government funding to bolster high-technology quantum communications for the space industry. ACT Minister for Higher Education, Training and Research Meegan Fitzharris has announced $375,000 in government...

Twisted light record boosts secure communication

Optical communications could be enhanced by controlling the amount of twist in the light, allowing you to send more information with fewer photons. Scientists from Australia, Austria and Canada have broken the world record for twisting light, opening...

Quantum computing a step closer to reality

Physicists at The Australian National University (ANU) have brought quantum computing a step closer to reality by stopping light in a new experiment. Lead researcher Jesse Everett said controlling the movement of light was critical to developing future...

QuintessenceLabs wins global award

A high-technology company started by physicists from The Research School of Physics and Engineering has won a major international award for its quantum cyber-security technology. QuintessenceLabs was named one of the top emerging innovation companies...

Laser tripod for better levitation

Physicists from The Australian National University have shown that three lasers are better than one when it comes to levitating small but visible objects on light, designing an extremely precise sensor by floating a mirror on a tripod of lasers. “Levitation...

Sounds of silence proving a hit

Researchers at The Australian National University have developed the fastest random number generator in the world by listening to the ‘sounds of silence’. The researchers – Professor Ping Koy Lam, Dr Thomas Symul and Dr Syed Assad...
