Accessible information in quantum measurement
The amount of information that can be accessed via measurement of a quantum system prepared in different states is limited by the Holevo bound. We present a simple proof of this theorem and its extension to sequential measurements based on the properties of quantum conditional and mutual entropies. The proof relies on a minimal physical model of the measurement which does not assume environment...
متن کاملAccessible information and quantum operations
It is impossible to perfectly clone an unknown quantum state using unitary evolution [1]. That non-orthogonal states can’t be distinguished is well known [2]. In [3], Mor and Terno showed that an arbitrary state cannot be disentangled, a universal disentangling machine cannot exist. It is well known that the laws of quantum mechanics allow us to do many things superior comparing with classical ...
متن کاملQuantum computing and communication
A quantum computer, if built, will be to an ordinary computer as a hydrogen bomb is to gunpowder, at least for some types of computations. Today no quantum computer exists, beyond laboratory prototypes capable of solving only tiny problems, and many practical problems remain to be solved. Yet the theory of quantum computing has advanced significantly in the past decade, and is becoming a signif...
متن کاملSpintronics and Quantum Dots for Quantum Computing and Quantum Communication
Control over electron-spin states, such as coherent manipulation, filtering and measurement promises access to new technologies in conventional as well as in quantum computation and quantum communication. We review our proposal of using electron spins in quantum confined structures as qubits and discuss the requirements for implementing a quantum computer. We describe several realizations of on...
