Professor Margaret Daphne Reid from Swinburne University of Technology (Melbourne, Australia) is a Fellow of the Australian Academy of Science. She is known for her pioneering work in new fundamental tests of quantum theory, including teleportation and cryptography. Career Reid graduated from the University of Auckland with a B.Sc. in 1978 and an M.Sc. in theoretical physics in 1980. She then undertook Ph.D. studies at Auckland University with Dan Walls FRS, graduating in 1984 with a doctoral thesis titled Squeezing and quantum effects in optics. She developed theories for the generation of squeezed states of light and quantum non-demolition measurement. Following several years as a lecturer at the University of Waikato, New Zealand, she was awarded an Australian QEII Fellowship to do research at the University of Queensland. She later became a researcher with the Australian Research Council Centre of Excellence in Quantum and Atom Optics at the University of Queensland. She is currently Professor at Swinburne University of Technology in Melbourne and works as a researcher within the Centre for Quantum and Optical Sciences. Research Reid's work has focused on the fundamental tests of quantum mechanics, including of the Einstein-Podolsky-Rosen paradox and Bell's theorem, based on parametric down conversion and quantum optics. On working with squeezed states of light in the 1980s, Reid thought of a way to test entanglement, after noting scientists were able to amplify and detect the tiny quantum fluctuations of optical amplitudes. Experiments since have confirmed this mesoscopic type of entanglement in a range of environments, which enables a closer understanding of Schrödinger's cat. In the 1990s, scientists realised one can securely transmit a message through encrypting and using a shared key generated by entanglement to decode the message from the sender and receiver. Using the quantum key meant the message was completely secure from interception during transmission. In a landmark publication, Reid's research group outlined Einstein's reservations about entanglement, a phenomenon he referred to as "'spooky' action at a distance". In this paper, a theoretical proof that such messages can be shared between more than two people and may provide unprecedented security for a future quantum internet, is provided for the first time. Sending entanglement to a larger number of people means the key can be distributed among all the receiving parties, so they must collaborate to decipher the message, which makes the message even more secure. The report showed that a secure message
