Artificial intelligence (AI) is coming at us before we fully understand what it might mean. Established ways of doing things in areas like transport regulation, crime prevention and legal practice are being challenged by new technologies such as driverless cars, crime prediction software and "AI lawyers". The possible implications of AI innovations for law and public policy in New Zealand will be teased out in a new, ground-breaking Law Foundation study. The three-year multi-disciplinary project, supported by a $400,000 Law Foundation grant, is being run out of the University of Otago. Project team leader Associate Professor Colin Gavaghan of the Faculty of Law says that AI technologies – essentially, technologies that can learn and adapt for themselves – pose fascinating legal, practical and ethical challenges.
A team from the University of Sydney (USyd), alongside Dartmouth College and Johns Hopkins Applied Physics Laboratory in the US, has announced solving a common problem in quantum sensing devices, effectively developing a method to block background "chatter". According to the university, the quantum control techniques enable new ultra-sensitive sensors that can identify tiny signals while rejecting background noise down to theoretical limits. Led by professor Michael J Biercuk, who is also the chief investigator at the ARC Centre of Excellence for Engineered Quantum Systems, the team has managed to "trick" devices that are too sensitive to block out background noise. "By applying the right quantum controls to a qubit [quantum bit]-based sensor, we can adjust its response in a way that guarantees the best possible exclusion of the background clutter -- that is, the other voices in the room," professor Biercuk explained. USyd said that while devices themselves have improved, the measurement protocols used to capture and interpret the signals have lagged behind and quantum sensors therefore often return "fuzzy" results, complicating the interpretation of the data through a phenomenon known as "spectral leakage".
