Quantum automata and quantum grammars
To study quantum computation, it might be helpful to generalize structures from language and automata theory to the quantum case. To that end, we propose quantum versions of finite-state and push-down automata, and regular and context-free grammars. We find analogs of several classical theorems, including pumping lemmas, closure properties, rational ...

On quantum ensembles of quantum classifiers [PDF]
Quantum machine learning seeks to exploit the underlying nature of a quantum computer to enhance machine learning techniques. A particular framework uses the quantum property of superposition to store sets of parameters, thereby creating an ensemble of quantum classifiers that may be computed in parallel.

Quantum metrology with molecular ensembles [PDF]
The field of quantum metrology promisesmeasurement devices that are fundamentally superior to conventional technologies. Specifically, when quantum entanglement is harnessed, the precision achieved is supposed to scale more favorably with the resources ...

Fertility progression in Germany: An analysis using flexible nonparametric cure survival models
Objective: This paper uses data from the German Socio-Economic Panel (GSOEP) to study the transition to second and third births. In particular, we seek to distinguish the factors that determine the timing of fertility from the factors that influence ...

Quantum Physics, Quantum Biology, Quantum Medicine?
The leading cause and foremost reason for mortality and morbidity in the world is a group known as Noncommunicable Diseases. The best approach to treat them is to evaluate and control the risk factors. There are shared by all these diseases leading to the existence of some meeting points behind all of them.

Quantum computation with quantum dots [PDF]
We propose a new implementation of a universal set of one- and two-qubit gates for quantum computation using the spin states of coupled single-electron quantum dots. Desired operations are effected by the gating of the tunneling barrier between neighboring dots.

Quantum Dissipation and Quantum Noise [PDF]
We derive the exact action for a damped mechanical system ( and the special case of the linear oscillator) from the path integral formulation of the quantum Brownian motion problem developed by Schwinger and by Feynman and Vernon. The doubling of the phase-space degrees of freedom for dissipative systems and thermal field theories is discussed and the ...
