... The density operator formalism was introduced by von Neumann (von Neumann, 1932). He wanted to deal with situations in which the quantum state of our system is ambiguous, i.e., one that cannot be represented by a vector in a Hilbert space. Such an ambiguity can result, for example, from our incomple ...

... system at time T will be very close to the ground state of H(T ), thus producing the desired solution. For this algorithm to be considered successful we require that T grow only polynomially in n, the number of bits. In this paper we analyze three examples where T grows only polynomially in n. We ar ...

... [18]. For example, 2-qubit gates may physically take up to 10 times the latency of 1-qubits gates. Moreover, by choosing QT as the method of communication, we mask the latency of moving qubits around. This masking is possible by pre-distribution of these pairs before they are needed for the teleport ...

Quantum group

In mathematics and theoretical physics, the term quantum group denotes various kinds of noncommutative algebra with additional structure. In general, a quantum group is some kind of Hopf algebra. There is no single, all-encompassing definition, but instead a family of broadly similar objects.The term ""quantum group"" first appeared in the theory of quantum integrable systems, which was then formalized by Vladimir Drinfeld and Michio Jimbo as a particular class of Hopf algebra. The same term is also used for other Hopf algebras that deform or are close to classical Lie groups or Lie algebras, such as a `bicrossproduct' class of quantum groups introduced by Shahn Majid a little after the work of Drinfeld and Jimbo.In Drinfeld's approach, quantum groups arise as Hopf algebras depending on an auxiliary parameter q or h, which become universal enveloping algebras of a certain Lie algebra, frequently semisimple or affine, when q = 1 or h = 0. Closely related are certain dual objects, also Hopf algebras and also called quantum groups, deforming the algebra of functions on the corresponding semisimple algebraic group or a compact Lie group.Just as groups often appear as symmetries, quantum groups act on many other mathematical objects and it has become fashionable to introduce the adjective quantum in such cases; for example there are quantum planes and quantum Grassmannians.
