Education

Crispin Gardiner completed his undergraduate studies at the University of Auckland (B. Sc. 1964, M. Sc. 1965) and received his D Phil in 1968 from the Oxford University for research in elementary particle physics.

Career

Following his D Phil, Gardiner completed postdoctoral research in the group of George Sudarshan at the Syracuse University.

University of Waikato 1970–1995

He was appointed to the faculty of the Physics Department of the University of Waikato in 1970, and was awarded a personal chair in physics in 1992, a position held until 1995. When Gardiner arrived, the University of Waikato was only 5 years old, while the School of Science, which covered Physics, Mathematics, Chemistry, Biology and Earth Science, had only commenced teaching at the beginning of 1970, and no research facilities had been established.[2]

Dan Walls took up a position at Waikato in 1972[3], and, working together, he and Gardiner established a major research centre for theoretical quantum optics at Waikato, building active and productive collaborations with groups throughout the world[3].

During this period

  • He and Matthew Collett developed the input-output formalism [5] for damped quantum systems, which they used [6]to predict and describe the spectrum of squeezed light.
  • He wrote the first (1985) edition of the book Stochastic Methods [7], now seen as a standard text in the field of applied stochastic processes [8].
  • In 1986 he predicted the inhibition of atomic phase decays for a two-level atom coupled to a squeezed optical reservoir [9]. While challenging to realise in optical systems, the phenomenon was eventually observed in a superconducting qubit system affording sufficient reservoir control [10].
  • He wrote the first (1991) edition of the book "Quantum Noise"[11], (later editions were written in collaboration with Peter Zoller) which has become a standard text [12] in the fields of quantum optics and quantum stochastic methods.
  • In 1993 he developed (at the same time as a separate formulation by Howard Carmichael) the theory and application of cascaded quantum systems, in which the optical output of one quantum system becomes the optical input for another quantum system.[13][14]

Independent Researcher at Victoria University of Wellington 1995–2005

In 1995 he left the University of Waikato and for the next nine years worked as an independently funded researcher affiliated to Victoria University of Wellington. This was funded by the New Zealand R&D system, which was willing to fund individuals outside established institutions, and was motivated by the opportunity to leave the increasingly bureaucratic New Zealand University system.[15] During this period his work concentrated on the physics of Ultracold atoms, developing a collaboration with Rob Ballagh of the University of Otago. They produced number of influential scientific publications, mainly concentrating on kinetic processes in Bose–Einstein condensates, funded by successive research contracts with the Marsden Fund [16] [17] [18] [19] [20] [21] and in particular seven papers on quantum kinetic theory [22] [23] [24] [25] [26] [27] [28].

Gardiner characterised this period as "In terms of productivity, it has been the best 10 years research of my life."[15]

University of Otago 2005–2013

In 2005 he was appointed as a Research Professor at the University of Otago. In this period he was active in developing the University of Otago as a major research centre in ultracold atoms, photonics and quantum optics, which was named the Jack Dodd Centre, after former Otago professor Jack Dodd. During this period there was a major reorganisation of government research funding, commencing in 2006, which he and Rob Ballagh strongly criticised[29], on the grounds that this would exclude university research from any major funding. Ultimately this aspect of the funding reform was not implemented, and in 2007 the Jack Dodd Centre was awarded a $6.4 million research contract[30] by the Foundation for Research, Science and Technology.

From that time on, as director of the Jack Dodd Centre, his role developed more into that of a research leader until his retirement in early 2013.

Retirement

On retirement he became an honorary professor at the University of Otago and in 2016 he accepted a position as visiting fellow at the Institute for Quantum Optics and Quantum Information (IQOQI) in Innsbruck.

During this period he and Peter Zoller wrote the three books of The Quantum World of Ultra-Cold Atoms and Light[31]
