Avshalom Cyrus Elitzur (Hebrew: אבשלום כורש אליצור), born 30 May 1957, is an Iranian-born Israeli physicist and philosopher.

He left school at the age of sixteen and began working as a laboratory technician at the Weizmann Institute of Science in Rehovot.

He is noted for the Elitzur–Vaidman bomb tester experiment in quantum mechanics, which was publicised by Roger Penrose in his book Shadows of the Mind.

That year, he was invited to present an unpublished manuscript on quantum mechanics at an international conference in Temple University in Philadelphia.

[2] In 2010, Elitzur won the Noetic Medal of Consciousness and Brain Research for his contributions to the cosmology of the mind and Quantum Theory.
