Arthur-Merlin and Black-Box Groups in Quantum
... from the 80s—MA, AM, black-box groups—and how they came to play a major role in quantum computing theory What should you conclude from this? (1) Laci works on the trendiest areas before they even exist (2) Quantum computing can’t be that scary (3) Beautiful mathematical structures (like finite group ...

Quantum Computing
... A bit of data is represented by a single atom that is in one of two states denoted by |0> and |1>. A single bit of this form is known as a qubit A physical implementation of a qubit could use the two energy levels of an atom. An excited state representing |1> and a ground state representing |0>. Lig ...

Quantum Mechanics
... Quantum mechanics is the branch of physics that mathematically describes the wave properties of submicroscopic particles. – We can no longer think of an electron as having a precise orbit in an atom. – To describe such an orbit would require knowing its exact position and velocity. – In 1927, Werner ...
