On May 16, 1960, American physicist Theodore Maiman presents the world's first operating laser at Hughes Research Laboratories, Malibu, California. Today, lasers are present everywhere, ranging from common consumer devices such as DVD players, laser printers, and barcode scanners to professional laser devices for surgery and various other skin treatments, or in industry for cutting and welding materials. Actually, it was Albert Einstein, who has laid the theoretical foundations for the laser in his 1917 paper Zur Quantentheorie der Strahlung (On the Quantum Theory of Radiation).
On August 8, 1902, English theoretical physicist Paul Adrien Maurice Dirac was born. Dirac is best known for his fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics.
On October 7, 1885, Danish physicist and Nobel Laureate Niels Bohr was born. Bohr made foundational contributions to understanding atomic structure and quantum mechanics, for which he received the Nobel Prize in Physics in 1922.

A. Harrow, A. Hassidim, and S. Lloyd. (2008)cite arxiv:0811.3171Comment: 15 pages. v2 is much longer, with errors fixed, run-time improved and a new BQP-completeness result added. v3 is the final published version and mostly adds clarifications and corrections to v2.
