Education and career

Cory was educated at Case Western Reserve University, earning a bachelor's degree there in 1981 and a Ph.D. in chemistry in 1987.{{citation|title=Alum Updates|url=http://www.case.edu/artsci/chem/design/newsletter/casechemist_2010-2011_5.5x8.5-final_sm.pdf|page=7|journal=The Case Chemist|volume=104|date=Winter 2010–2011}}.{{cite thesis |last1=Cory |first1=David G. |year=1987 |title=Applications of cross polarization spin dynamics in solids |publisher=Case Western Reserve University |oclc=16259096 }} He carried out postdoctoral research at Radboud University Nijmegen in the Netherlands and at Naval Research Laboratory in Washington, D.C. He was a Professor of Nuclear Engineering at Massachusetts Institute of Technology prior to his 2010 appointment at Waterloo. At MIT, he worked on NMR, including his work on NMR quantum computation.{{citation|title=Programming the Universe: A Quantum Computer Scientist Takes on the Cosmos|first=Seth|last=Lloyd|publisher=Alfred A.

Together with Amr Fahmy and Timothy Havel he developed the concept of pseudo-pure states and performed the first experimental demonstrations of NMR quantum computing.{{Cite journal |last1=Cory |first1=David G. |last2=Fahmy |first2=Amr F. |last3=Havel |first3=Timothy F. |date=1997-03-04 |title=Ensemble quantum computing by NMR spectroscopy |journal=Proceedings of the National Academy of Sciences |language=en |volume=94 |issue=5 |pages=1634–1639 |doi=10.1073/pnas.94.5.1634 |issn=0027-8424 |pmc=19968 |pmid=9050830|bibcode=1997PNAS...94.1634C |doi-access=free }}{{citation|journal=MIT News|title=MIT researchers create quantum computer that simulates quantum system|date=June 25, 1999|url=http://newsoffice.mit.edu/1999/quantum}}

Cory's research also concerns the realization and application of quantum control in various physical systems and devices. In 2015, he and teams from University of Waterloo, National Institute of Standards and Technology and Boston University demonstrated the generation and control of orbital angular momentum of neutron beams using a fork-dislocation grating,{{Cite journal |last1=Clark |first1=Charles W. |last2=Barankov |first2=Roman |last3=Huber |first3=Michael G. |last4=Arif |first4=Muhammad |last5=Cory |first5=David G. |last6=Pushin |first6=Dmitry A. |date=2015-09-23 |title=Controlling neutron orbital angular momentum |url=http://www.nature.com/articles/nature15265 |journal=Nature |language=en |volume=525 |issue=7570 |pages=504–506 |doi=10.1038/nature15265 |pmid=26399831 |bibcode=2015Natur.525..504C |s2cid=4454300 |issn=0028-0836}} extending the existing work in optical and electron beams to neutrons. They subsequently demonstrated the control of both the spin and orbital angular momentum degrees of freedom of neutron beams.{{Cite journal |last1=Sarenac |first1=D |last2=Nsofini |first2=J |last3=Hincks |first3=I |last4=Arif |first4=M |last5=Clark |first5=Charles W |last6=Cory |first6=D G |last7=Huber |first7=M G |last8=Pushin |first8=D A |date=2018-10-10 |title=Methods for preparation and detection of neutron spin-orbit states |journal=New Journal of Physics |volume=20 |issue=10 |pages=103012 |doi=10.1088/1367-2630/aae3ac |issn=1367-2630 |pmc=8634251 |pmid=34858077|arxiv=1803.02295 |bibcode=2018NJPh...20j3012S }}{{Cite journal |last1=Sarenac |first1=Dusan |last2=Kapahi |first2=Connor |last3=Chen |first3=Wangchun |last4=Clark |first4=Charles W. |last5=Cory |first5=David G. |last6=Huber |first6=Michael G. |last7=Taminiau |first7=Ivar |last8=Zhernenkov |first8=Kirill |last9=Pushin |first9=Dmitry A. |date=2019-10-08 |title=Generation and detection of spin-orbit coupled neutron beams |journal=Proceedings of the National Academy of Sciences |language=en |volume=116 |issue=41 |pages=20328–20332 |doi=10.1073/pnas.1906861116 |issn=0027-8424 |pmc=6789912 |pmid=31548384|arxiv=1904.09520 |bibcode=2019PNAS..11620328S |doi-access=free }}
