Mathematical Aspects of Quantum Theory and Quantization Summer
... mathematics on the one hand and empirical knowledge of physical phenomena on the other hand. Here, in the midst of North Africa, the contribution of Arabs scientists, such as al-Tusi, al-Kwarizmi, al-Haytham, and many others, deserves to be mentioned. They not only preserved classical knowledge but ...

... of states by S (H). Each unit vector ψ ∈ H defines a one-dimensional projection φ → ψ | φψ , which we denote by Pψ . These kind of operators are the extreme elements of the convex set S (H), and we refer to them as pure states. An observable having the Borel space (R, B(R)) as outcome space is re ...

According to this description, the transition from classical to quantum mechanics can be understood as a substitution of a commutative algebra of functions – relative to pointwise multiplication – by a non-commutative algebra of operators. ...

Are Quantum States Exponentially Long Vectors?
... does BQP/qpoly = BQP/poly, where BQP/poly is the class of problems solvable in quantum polynomial time with the aid of polynomial-size classical advice? As usual in complexity theory, the answer is that we don’t know. This raises a disturbing possibility: could quantum advice be similar in power to ...
