The main research of Lev Vaidman is in the fields of Foundations of Quantum Mechanics and Quantum Information.
- Most of his works belong to theoretical physics, but he also performs some experimental work in quantum optics and writes philosophical papers on the many-worlds interpretation of quantum mechanics.
- His main contributions are variants of quantum measurements: interaction-free measurements (the Elitzur-Vaidman bomb problem), protective measurements, weak measurements (the Aharonov-Albert-Vaidman Effect), non-local measurements (which led to discovery of teleportation of continuous variables).
- In the area of Quantum Information he invented a secret key distribution with quantum particles in orthogonal states (the Goldenberg-Vaidman protocol), quantum gambling, and practically secure bit commitment.
- The main tool of his research is the analysis of paradoxes such as the 3-box paradox, the paradox of a photon being at a place through which it cannot pass and more. The Paradoxes help him achieve the goal of deeper understanding of locality and randomness in Nature.
