Quantum algorithms are conventionally formulated for implementation on a single system of qubits amenable to projective measurements. However, in expectation value quantum computation, such as nuclear magnetic resonance realizations, the computer consists of an ensemble of identical qubit-systems amenable only to expectation value measurements. The prevalent strategy in such expectation value i...

In nonextensive statistical mechanics, two kinds of definitions have been considered for expectation value of a physical quantity: one is the ordinary definition and the other is the normalized q-expectation value employing the escort distribution. Since both of them lead to the maximum-Tsallis-entropy distributions of a similar type, it is of crucial importance to determine which the correct p...

We show how the renormalization constant of Higgs vacuum expectation value, fixed by a tadpole condition, is responsible for gauge dependences in various definitions parameters $R_{\xi}$-gauge. Then we relationship this to Fleischer-Jegerlehner (FJ) scheme, which used avoid these dependences. In way, also present viewpoint on FJ-scheme complementary ones already existing literature. Additionall...
