You might not know it, but Australia is an unexpected frontrunner in the race to build a quantum computer. 

Despite our isolation, leading quantum experts have called Australia home for decades, chipping away at this massive challenge. 

What have we learnt, from our first digital computer CSIRAC, to now? And will it all culminate in the world's first million-qubit computer?

It's 1994, and a mathematical algorithm puts a spotlight on quantum computing for the first time.

Defence departments, spy agencies and cybersecurity experts are on edge over the explosive Shor's algorithm.

They spend decades and billions of dollars searching for a solution before something called "Q-day" arrives.

Google announces it has achieved something game changing — quantum supremacy. But not everybody agrees.

The company claims its quantum computer called Sycamore has solved a problem that no classical computer could manage in hundreds of thousands of years. 

IBM wants this stricken from history.

A war of words breaks out as two tech giants race to build a useful quantum computer that could change how the world works.

On “quantum supremacy” - IBM

Quantum computers could be the next giant leap in technology — transforming how we heal people, how we grow food, how we get around our cities.

So how close are we to the quantum future we've been promised?

For Science Friction on ABC Radio National, Jacinta Bowler unpacks how the weird world of quantum physics could change everything.

Hear about the surprising twists, the quantum cat-fights and the plucky heroes that have defined humanity's effort to build nature's most unpredictable machine. 

Dead and Alive is a four-part series from Science Friction on ABC Radio National. Episode 1 is out Wednesday July 8th.

The Integrity astronauts are back on Earth recovering from their journey, while NASA prepares for Artemis III. 

Belinda and Jacinta answer some of your questions in the wake of a successful moon orbit mission.

There wasn't a dry eye in mission control as the Artemis II astronauts safely returned in what NASA called a "perfect" splashdown.

Belinda and Jacinta relive the historic re-entry, and dig into the wild physics associated with blasting through Earth's atmosphere and plopping into the ocean.

Nine days down … only one to go.

The Artemis II mission is currently hurtling through space back to Earth, and is expected to land in the Pacific Ocean off the Californian coast tomorrow morning, Australia time.

Belinda and Jacinta find out what the four astronauts on board have been doing as they make their approach, including being sent on an impromptu scavenger hunt, and what they can expect to feel as they re-enter Earth's atmosphere.

With under two days to go, the Artemis II astronauts are making the most of their remaining time in space. 

Belinda and Jacinta take a look at what they've been up to in the lead up to re-entry, and what they can expect to feel as they return to Earth.

And if you've ever wondered what urine looks like as it's sprayed into space, well, we have you covered.

After the high of the lunar flyby, the four Artemis II astronauts are now on the return leg of their mission while scientists pore over the thousands of images sent back to Earth so far. 

Belinda and Jacinta delve into some surprising observations from the flyby, and answer more listener questions about everything from space navigation to the need for belts in weightlessness.

It’s been a big day for the Artemis II astronauts. They broke a 56-year record for the furthest distance humans have travelled from Earth, successfully looped around the Moon, and capped off the flyby with a solar eclipse. 

Belinda and Jacinta break down what the crew saw as they gazed upon the Moon’s far side and why they lost contact with mission control for 40 minutes.

We’re at the pointy end of the Artemis II mission now: It’s the eve of the lunar flyby. 

With the four astronauts now looped into the Moon’s gravitational clutches, they’ll have an intense few hours observing the lunar surface, taking photos, and breaking Apollo 13’s record for humans furthest from Earth. 

Artemis Explained is a daily podcast from ABC Radio National.  From lift-off to splashdown, we'll bring you daily Artemis II mission updates and answer your questions about life as an astronaut, the science of spaceflight, and plans to venture beyond the Moon.
