Sending quantum messages over long distances will be challenging. The signal will have to be amplified every few hundred kilometres, but conventional optical amplification would destroy the quantum message.
In a quantum information system, if you measure the light, you will destroy the information encoded on it. You need to store the light itself.
“We have to catch and store the light, but we’re not allowed to look at it to see what information it contains. If the system is working, the light will be exactly the same when we let it out again. We do this by absorbing the light into a cloud of atoms,” says Dr Ben Buchler.
Polymers are being used for non-stick coatings, anti-fouling technology, precision drug delivery, medical diagnosis, imaging, and many other applications.

Associate Professor Cyrille Boyer’s ideas are built on the revolutionary RAFT techniques (a technique to precisely control how small molecules are linked together to form large polymer chains) for which Professor David Solomon and Dr Ezio Rizzardo received the 2011 Prime Minister’s Prize for Science. His latest technology uses light and chlorophyll to catalyse the production of polymers.
Hot and salty water is a common by-product of industries such as textiles, food and dairy production. But new technology that allows this water to be purified, collected and re-used on site has been developed by Victorian scientists.
Their compact module, smaller than the size of a human, can transform a wasteful industrial operation into an efficient process that recycles energy, water and materials.
“We’ve calculated that our module can reduce water use by more than 90 per cent in some industrial settings,” Professor Mikel Duke says.
Port cities can be lively, vibrant hives of activity—the hub of a nation’s economic health— if they’re planned well.
Indonesia’s busiest port, Tanjung Priok, has roughly two and a half times the container traffic as the Port of Melbourne. But it also has a reputation as one of the least efficient ports in Asia.
Indonesian President Joko Widodo has recognised the need to transform the nation’s ports and plans to develop 24 new ports by 2019. One recently established, state-of- the-art port is Teluk Lamong in Surabaya.
We know the Southern Ocean plays a big role in our climate, but there’s much to learn about how and where clouds form over the sea, how they influence global temperatures, and how the wind affects cloud formation and how much carbon dioxide our oceans can absorb.

Now a 60m ‘wave pool in a wind tunnel’ built by Associate Professor Jason Monty is allowing researchers from The University of Melbourne, Swinburne, and Monash University to find out.
“We know that small eddies at the surface of the ocean affect how evaporation occurs and gasses are exchanged, but this turbulence is not included in climate models, as no one has been able to measure it,” Jason says.
Cool thinking by an Australian defence scientist while a bushfire bore down on his family home provided first responders with clearer satellite images of the blaze, and likely prevented further devastation.

The Sampson Flat bushfires in South Australia claimed the lives of around 900 animals, destroying 27 houses along with other property in January 2015.
Chris Ekins evacuated his family, but while preparing to protect their home he heard on local ABC radio that aircraft were having difficulty seeing through the smoke.
Zircon, the oldest mineral on the planet, is helping geologists understand how Earth started out and how it continues to evolve. By better understanding the Earth’s structure, mining companies have been able to find new mineral deposits.

“Most of the mineral deposits that are exposed on the surface of the planet have already been found and mined, but we need to find the ones that are still hidden,” Dr Elena Belousova says.
She and her colleagues at the ARC Centre of Excellence for Core to Crust Fluid Systems have developed TerraneChron®, a tool that looks at zircons found in geological samples, such as rocks or sand in river beds, to find out when they crystallised.
Gene therapy clinical trials are underway to treat one of the leading causes of blindness in the developed world.
The treatment for wet age-related macular degeneration (more advanced than dry macular degeneration) will hopefully be available to patients within three years, says the team at the Lions Eye Institute in Western Australia.
They’re using a modified virus to carry a gene into the cells at the back of the eye. The delivered gene encourages these cells to continuously secrete medication to treat the problem.
The development of a two-quantum bit (qubit) logic gate in silicon heralds the possibility of moving quantum computers from experimental lab to large-scale manufacture much faster than other global research efforts.

Scientia Professor Andrew Dzurak and his team have created a two-qubit gate – a critical component, which allows qubits to talk to each other and will form the basis for a quantum computer chip.
It’s an advance that the UK’s premier physics magazine, Physics World, declared one of the top 10 breakthroughs of 2015.
Traditional buildings in Indonesia make use of ‘passive’ cooling techniques. Being well ventilated, raised off the ground, and with shady verandas, their design allows them to stay cool in a tropical climate without air conditioning. The classic timber ‘Queenslander’ house also follows a similar design.
Now architects and engineers from both countries are getting together to compare notes on such designs and materials.
