Alexei Yurievich Kitaev (Russian: Алексей Юрьевич Китаев; born August 26, 1963) is a Russian–American professor of physics at the California Institute of Technology and permanent member of the Kavli Institute for Theoretical Physics. He is best known for introducing the quantum phase estimation algorithm and the concept of the topological quantum computer while working at the Landau Institute for Theoretical Physics. He is also known for introducing the complexity class QMA and showing the 2-local Hamiltonian problem is QMA-complete, the most complete result for k-local Hamiltonians. Kitaev is also known for contributions to research on a model relevant to researchers of the AdS/CFT correspondence started by Subir Sachdev and Jinwu Ye; this model is known as the Sachdev–Ye–Kitaev (SYK) model.




Life


Kitaev was educated in Russia, receiving an M.Sc. from the Moscow Institute of Physics and Technology (1986), and a Ph.D. from the Landau Institute for Theoretical Physics under the supervision of Valery Pokrovsky in 1989. He served previously as a researcher (1999–2001) at Microsoft Research, a research associate (1989–1998) at the Landau Institute and a professor at Caltech (2002–present).




Honors and awards


In 2008 Kitaev was awarded a MacArthur Fellowship.
In July 2012, he was an inaugural awardee of the Breakthrough Prize in Fundamental Physics, the creation of physicist and internet entrepreneur, Yuri Milner.
In 2015, he was jointly awarded the 2015 Dirac Medal by ICTP.
In 2017, he was, together with Xiao-Gang Wen, the winner of the Oliver E. Buckley Condensed Matter Prize.
In 2021, he was elected into the National Academy of Sciences.
In 2024, he received the Henri Poincaré Prize from the International Association of Mathematical Physics.
In 2024, he was awarded a 2024 Basic Science Lifetime Award in Theoretical Physics.




Political positions


In February–March 2022, he signed an open letter by Breakthrough Prize laureates condemning the 2022 Russian invasion of Ukraine.
