Howard Carmichael

Howard John Carmichael is a New Zealand theoretical physicist specialising in quantum optics and the theory of open quantum systems[1][2] He is the Dan Walls Professor of Physics at the University of Auckland. He is the originator of Quantum Trajectory Theory and is using this theory to contribute to the development of quantum computers.[3] Carmichael is a Fellow of Optical Society of America, the American Physical Society and the Royal Society of New Zealand. He was awarded the Max Born Award in 2003 and the Humboldt Research Award in 1997. In 2015, he was recognised as an Outstanding Referee by the American Physical Society.

Biography and education

Carmichael was born in Manchester England on January 17, 1950.[1] He emigrated to New Zealand where he began his education. He gained a BSc in physics and mathematics in 1971, and a first class honours MSc in physics in 1973 at the University of Auckland.[1] He then went to the University of Waikato, obtaining his PhD in 1977, supervised by Dan Walls. After post-doctoral positions at the City University of New York, and at the University of Texas at Austin (1979–1981) he was appointed as an assistant professor and later associate professor at the University of Arkansas. He was a visiting scientist at the Royal Signal and Radar Establishment in Malvern in 1984, visiting professor at the University of Texas at Austin in 1988 and at Caltech in 1989. In 1989 he was made associate professor, and in 1991 full professor, at the University of Oregon. He returned to New Zealand in 2002[4] to join the University of Auckland, becoming the inaugural Dan Walls Professor of Physics, a position he still holds today.[1][5]

Areas of research
  • While Carmichael was still a graduate student he and his doctoral supervisor Dan Walls published a seminal paper [6] that showed how to create antibunched light, in which photons arrive at regular intervals, rather than randomly.
  • In the early 1990s he developed the quantum jump method (at essentially the same time as the separate formulations by Dalibard Castin & Mølmer, and by Zoller, Ritsch & Dum) as a technique for simulating and understanding quantum optical systems.
  • In 1993 he developed (at the same time as a separate formulation by Crispin Gardiner) 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.[7][8]

gollark: I made some perfectly nice elegant formulae for this and yet no governments spontaneously adopted them.
gollark: Simple and objective performance measurements, maybe.
