Quantum Computing

Scientists have unveiled a new approach to powering quantum computers using quantum batteries -- a breakthrough that could make future computers faster, more reliable and more energy efficient.

Macquarie University researchers have fully mapped how noise spreads through quantum computers over time to show that glitches link together across different moments, creating a form of 'memory' that undermines calculations.

Quantum satellites currently beam entangled particles of light from space down to different ground stations for ultra-secure communications. New research shows it is also possible to send these signals upward, something once thought unfeasible.

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate.

Creating new drugs or medical treatments are some of the great promises of quantum computing. Scientists at the University of Sydney have, for the first time, used a quantum computer to simulate the chemical dynamics of real compounds, a vital step towards modelling more complex molecules and designing bespoke chemicals that could lead to improved sunscreen or skin cancer treatments.
