Alexander Lvovsky

Lvovsky attended Moscow State School 57, a school renowned for its focus on mathematics and physics. He earned his undergraduate degree in physics from the Moscow Institute of Physics and Technology in 1993. He then attended Columbia University in New York City, completing a Master of Arts and Master of Philosophy in Physics in 1996 and a Ph.D. in 1998. His doctoral advisor was Sven R. Hartmann, and his dissertation focused on superradiance in atomic gases.{{cite web|title=Alexander Lvovsky.

After completing his Ph.D., Lvovsky was a postdoctoral researcher at the University of California, Berkeley (1998–1999). He subsequently joined the University of Konstanz in Germany as an Alexander von Humboldt postdoctoral fellow (1999–2001) and later headed an Emmy Noether research group in quantum-optical information technology until 2004.{{cite web |title=Experimente zur Erzeugung, Verarbeitung und Charakterisierung nichtklassischer Zustände des Lichtfelds |url=https://gepris.dfg.de/gepris/projekt/5348563 |website=Deutsche Forschungsgemeinschaft (DFG)}} In 2004, Lvovsky became a faculty member in the Department of Physics and Astronomy at the University of Calgary, Canada, where he held a Canada Research Chair{{cite web |title=NSERC's Awards Database |url=https://www.nserc-crsng.gc.ca/ase-oro/Details-Detailles_eng.asp?id=385070 |website=Natural Sciences and Engineering Research Council of Canada}} and advanced research in quantum information science. In 2018, he joined the University of Oxford as a Professor of Physics, continuing his work in quantum optics and optical computing.

Lvovsky was involved in establishing the {{Interlanguage link|Russian Quantum Center|ru|3=Российский_квантовый_центр}} and led a research group there between 2013 and 2022.{{cite web |title=People |url=https://rqc.ru/people |website=Russian Quantum Center}}

Lvovsky's research focuses on quantum optics and its applications in technology and information processing, as well as optical computing and neural networks.{{Cite web|url=https://quantech.group/|title=Quantum and optical technology. Research group home page}}

Lvovsky's book Quantum Physics: An Introduction Based on Photons offers in alternative approach to teaching quantum mechanics. The book uses photon polarization as the underlying physical system and teaches entanglement early on in the course, rather than as an advanced concept. This is motivated by the understanding that entanglement is key to the inherent logic of quantum physics, particularly the nature of quantum measurement, clarifying the role of observer in it.{{cite book |last1=Lvovsky |first1=A. I. |title=Quantum Physics: An Introduction Based on Photons |date=25 May 2018 |publisher=Springer |isbn=978-3-662-56582-7}}

Lvovsky established and is leading two educational outreach programmes providing small-group tutorials to senior secondary school students in the UK, delivered mainly by Oxford Physics undergraduate students:

• COMPOS (Comprehensive Oxford Mathematics and Physics Online School) focusses on developing the students' advanced problem-solving skills in mathematics and physics within the school syllabus.{{cite web|title=Comprehensive Oxford Mathematics and Physics Online School|url=https://compos.web.ox.ac.uk/|website=Department of Physics, University of Oxford}}
• Quantum Club offers an academically rigorous quantum physics course, covering basic principles such as Hilbert space and measurement, as well as more advanced concepts including entanglement, nonlocality and teleportation.{{cite web |title=Oxford Quantum Club |url=https://www.physics.ox.ac.uk/engage/schools/secondary-schools/projects-and-mentoring/quantum-club|website=Department of Physics, University of Oxford}}

Lvovsky co-founded Lumai,{{cite web|title=LUMAI|url=https://lumai.ai/}}{{Cite journal |url=https://www.uktech.news/deep-tech/lumai-grant-20230215|journal=UKTN|title= Oxford optical computing startup Lumai awarded £1.1m grant|date=15 February 2023}} a spin-off company developing optical neural network technology aimed at high-speed, energy-efficient computing applications.

Lvovsky has received several awards, including the 2010 International Quantum Award.{{cite web|title=International Quantum Award|url=http://www.qcmc-conference.org/quantum-award.html}} He is a lifetime member of the American Physical Society and a Fellow of Optica.{{cite web|url=https://www.optica.org/get_involved/awards_and_honors/fellow_members/elected_fellows/|title=Elected Fellows|website=Optica}}

Lvovsky is married to Bhavya Rawal and they are raising three children.
