A few remarks on quadratic harnesses
We analyze and partially solve system of recurrences that can be derived from the properties of martingale orthogonal polynomials that characterize quadratic harnesses (QH). We also specify conditions for the existence of moments of one dimensional d...
Measurement-Disturbance Tradeoff Outperforming Optimal Cloning
One of the characteristic features of quantum mechanics is that every measurement that extracts information about a general quantum system necessarily causes an unavoidable disturbance to the state of this system. A plethora of different approaches h...
Alternate two-dimensional quantum walk with a single-qubit coin
We have recently proposed a two-dimensional quantum walk where the requirement of a higher dimensionality of the coin space is substituted with the alternance of the directions in which the walker can move [C. Di Franco, M. Mc Gettrick, and Th. Busch...
Sonos 9.1.4 Theater Mini-Review - Audio Science Review (ASR) Forum
Dec 21, 2018 · Sonos provides adequate sound quality and is very easy to use setup. The separates root provides outstanding sound quality but is complex to setup and accomodate. I'm actually more …
Binding Energy of Impurity in a Size Quantized Coated Semiconductor Wire: Role o…
Within the framework of staircase infinitely deep (SIW) potential well model the effect of dielectric constant mismatch between the size-quantized semiconducting wire, coating and surrounding environment on impurity binding energy is considered. Ca...
Fast fluctuating fields as the source of low-frequency conductance fluctuations…
It is shown that in many-electron systems quantum transfer amplitudes and thus transfer probabilities may be strongly influenced by fast fluctuating fields, in particular, caused by simultaneous electron transfers. Corresponding mutual interplay of...
Turbulent Cold Flows Gave Birth to the First Quasars
How quasars powered by supermassive black holes (SMBHs) formed less than a billion years after the Big Bang is still one of the outstanding problems in astrophysics 20 years after their discovery$^{1-4}$. Cosmological simulations suggest that rare co...
Quantum Approximate Counting, Simplified
In 1998, Brassard, Hoyer, Mosca, and Tapp (BHMT) gave a quantum algorithm for approximate counting. Given a list of $N$ items, $K$ of them marked, their algorithm estimates $K$ to within relative error $\varepsilon$ by making only $O\left( \frac{1}{\...

Entanglement dynamics in open two-qubit systems via diffusive quantum trajectori…
We use quantum diffusive trajectories to prove that the time evolution of two-qubit entanglement under spontaneous emission can be fully characterized by optimal continuous monitoring. We analytically determine this optimal unraveling and derive a de...

Quasi-powerful $p$-groups
In this paper we introduce the notion of a quasi-powerful $p$-group for odd primes $p$. These are the finite $p$-groups $G$ such that $G/Z(G)$ is powerful in the sense of Lubotzky and Mann. We show that this large family of groups shares many of the...
Meson-exchange currents and quasielastic predictions for charged-current neutrin…
We evaluate and discuss the impact of meson-exchange currents (MECs) on charged-current quasielastic neutrino cross sections. We consider the nuclear transverse response arising from two-particle two-hole states excited by the action of electromagnet...
How can a quantum fluctuation create a universe?
Some minutes ago, I read an article saying there could have been empty space where a quantum fluctuation happened and created the universe. If this is true, would someone answer the following questio...

On the quantum "self-teleportation" probability of a human body
The probability of quantum relocation of a human body, at a given distance, is estimated using two different methods, giving comparable results. Not only the obtained values for the probabilities are inconceivably small, but assumptions of a sci-fi n...
