Lev Vaidman

Physics Department, Tel Aviv University Related

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.
