Shortly after NASA’s OSIRIS-REx spacecraft arrived at asteroid Bennu, an unexpected discovery by the mission’s science team revealed that the asteroid could be active, or consistently discharging particles into space...

A group of scientists led by 2018 Australian of the Year Professor Michelle Simmons has achieved the first two-qubit gate between atom qubits in silicon – a major milestone on the team’s quest to build an atom-scale quantum computer. The pivotal piece of research was published today in the journal Nature.

A two-qubit gate is the central building block of any quantum computer – and the UNSW team’s version of it is the fastest that’s ever been demonstrated in silicon, completing an operation in 0.8 nanoseconds, which is ~200 times faster than other existing spin-based two-qubit gates.

In the Simmons’ group approach, a two-qubit gate is an operation between two electron spins – comparable to the role that classical logic gates play in con...

Carbon nanotube films enable method to recycle waste heat. Engineers have shown how their carbon nanotube films can be used to create a device to recycle waste heat. The device could enhance solar cell output and increase the efficiency of industrial waste-heat recovery.

The ever-more-humble carbon nanotube may be just the device to make solar panels – and anything else that loses energy through heat – far more efficient.

Rice University scientists are designing arrays of aligned single-wall carbon nanotubes to channel mi...

Astronomers report first observations of a ‘circumplanetary disk’. Using Earth’s most powerful array of radio telescopes, astronomers have made the first observations of a circumplanetary disk of gas and dust like the one that is believed to have birthed the moons of Jupiter.

The find, reported online today in Astrophysical Journal Letters, adds to the intriguing story of planet PDS 70 c, a still-forming gas giant about 37...
