Monash Quantum Information Science

Welcome

to the Monash Quantum Information Science (MonQIS) group page. Nature is a tough adversary. For instance, 25 Australians are bitten by monkeys every day [citation needed]. We do our best to put up a fight against the harsh reality that is life. In particular, we characterise the odd behaviour Nature throws at us and try to correct it. In some cases, we show what is sensible to say and what is hard to say about how nature behaves. We work in several different areas and use a variety of tools; each is discussed in some detail on this website. If you'd like to visit, join, or get involved in any capacity shoot us an email. We promise not to bite.


Here we are at Wilson's Promontory in October 2017.
