Sudarshan has been credited with numerous contributions to the field of theoretical physics, including Glauber—Sudarshan P representation , V-A theory , tachyons , quantum Zeno effect , open quantum system and quantum master equations , spin—statistics theorem , non-invariance groups, positive maps of density matrices, and quantum computation.

He was raised in a Syrian Christian family , but later left the religion and converted to Hinduism following his marriage. He obtained his master's degree at the University of Madras in Homi Bhabha as well as others. Robert Marshak as a graduate student.

In , he received his Ph. At this point he moved to Harvard University to join Prof. Julian Schwinger as a postdoctoral fellow. Sudarshan made significant contributions to several areas of physics. He was the originator with Robert Marshak of the V-A theory of the weak force later propagated by Richard Feynman and Murray Gell-Mann , which eventually paved the way for the electroweak theory.

Feynman acknowledged Sudarshan's contribution in stating that the V-A theory was discovered by Sudarshan and Marshak and publicized by Gell-Mann and himself. Sudarshan's most significant work may have been his contribution to the field of quantum optics. His theorem proves the equivalence of classical wave optics to quantum optics.
