Post-quantum cryptography technology company BTQ recently announced that it has registered and established an Australian subsidiary in Sydney. The subsidiary will primarily advance its research and development efforts in quantum algorithms to enhance the security and efficiency of communications. In addition, it has also announced a partnership with Macquarie University and the Sydney Quantum Academy to cultivate the next generation of quantum technology specialists.

Physicists from the Australian National University have developed a new technology that can make light-based quantum technologies more accurate and efficient. Their multiport interferometer device based on a metasurface can provide on-the-fly error-checking capabilities. This tiny unit can be built into the quantum technology, so the device may be particularly useful in portable quantum systems, or on satellites. Experiments have shown that this device can successfully characterize the similarity of the photons’ spatial mode, polarization, and spectra.

The Australian government launched a quantum technologies challenge plan yesterday with a total funding of AUD 36 million. Quantum technology companies will be eligible for over AUD 5 million in support to address some nationally significant challenges. It's understood that the first stage of the plan will provide AUD 500,000 in funding for project feasibility studies, while the second stage(2025-2026) will offer up to AUD 5 million in funding for demonstration projects.

The University of Sydney Nano Institute has received substantial backing from the US government’s quantum computing funding program, with a $10 million grant over four years aimed at drastically improving existing quantum technology. The funding will allow the Sydney Nano team to deepen its research in quantum error correction and expand work with global industry, including collaboration with IBM scientists and access to IBM quantum systems over the cloud.
