abstract = {We use microwave excitation to elucidate the dynamics of long superconductor-normal metal-superconductor Josephson junctions. By varying the excitation frequency in the range 10 MHz-40 GHz, we observe that the critical and retrapping currents, deduced from the dc voltage versus dc current characteristics of the junction, are set by two different time scales. The critical current increases when the ac frequency is larger than the inverse diffusion time in the normal metal, whereas the retrapping current is strongly modified when the excitation frequency is above the electron-phonon rate in the normal metal. Therefore the critical and retrapping currents are associated with elastic and inelastic scattering, respectively. 2009 The American Physical Society.},

Abstract = {We present a theory of quantum serial turbo-codes, describe their iterative decoding algorithm, and study their performances numerically on a depolarization channel. Our construction offers several advantages over quantum LDPC codes. First, the Tanner graph used for decoding is free of 4-cycles that deteriorate the performances of iterative decoding. Secondly, the iterative decoder makes explicit use of the code's degeneracy. Finally, there is complete freedom in the code design in terms of length, rate, memory size, and interleaver choice.
We define a quantum analogue of a state diagram that provides an efficient way to verify the properties of a quantum convolutional code, and in particular its recursiveness and the presence of catastrophic error propagation. We prove that all recursive quantum convolutional encoder have catastrophic error propagation. In our constructions, the convolutional codes have thus been chosen to be non-catastrophic and non-recursive.
While the resulting families of turbo-codes have bounded minimum distance,
from a pragmatic point of view the effective minimum distances of the codes that we have simulated are large enough not to degrade the iterative decoding performance up to reasonable word error rates and block sizes. With well chosen constituent convolutional codes, we observe an important reduction of the word error rate as the code length increases. },

Abstract = {We present a quantum algorithm to prepare the thermal Gibbs state of interacting quantum systems. This algorithm sets a universal upper bound $D^\alpha$ on the thermalization time of a quantum system, where $D$ is the system's Hilbert space dimension and $\alpha \leq \frac 12$ is proportional to the Helmholtz free energy density of the system. We also derive an algorithm to evaluate the partition function of a quantum system in a time proportional to the system's thermalization time and inversely proportional to the targeted accuracy squared. },

Abstract = {Preparing the ground state of a system of interacting classical particles is an NP-hard problem. Thus, there is in general no better algorithm to solve this problem than exhaustively going through all $N$ configurations of the system to determine the one with lowest energy, requiring a running time proportional to $N$. A quantum computer, if it could be built, could solve this problem in time $\sqrt N$. Here, we present a powerful extension of this result to the case of interacting {\em quantum} particles, demonstrating that a quantum computer can prepare the ground state of a quantum system as efficiently as it does for classical systems. },

abstract = {We report the measurement of higher order cumulants of the current fluctuations in an avalanche diode with a stationary dc current. Such a system is archetypal of devices in which transport is governed by a collective mechanism, in this case charge multiplication by avalanche. We have measured the first five cumulants of the probability distribution of the current fluctuations. We show that the charge multiplication factor is distributed according to a power law that is different from that of the usual avalanche below breakdown, when avalanches are well separated. 2009 The American Physical Society.},

The device is aimed at studies of triple quantum dot properties where knowing the exact number of electrons is important as well as quantum information applications involving electron spin qubits. We demonstrate tuning strategies for achieving required resonant conditions such as quadruple points where all three quantum dots are on resonance. We find that in such a device resonant conditions at specific configurations are accompanied by complex charge transfer behavior. {\copyright} 2009 American Institute of Physics.},

Surprisingly the experimental results indicate similar properties at all four points. Fourier transform analysis of the magnetoconductance data reveal several dominant and related periods. Theoretical calculations suggest that with improved resolution future experiments should reveal configuration specific magnetoconductance results in the few electron regime. {\copyright} 2009 American Institute of Physics.},

abstract = {We describe a technique for characterizing bolometric detectors that have sufficient sensitivity to count single terahertz photons. The device is isolated from infrared blackbody radiation and a single terahertz photon is simulated by a fast microwave pulse, where the absorbed energy of the pulse is equal to the photon energy. We have employed this technique to characterize bolometric detectors consisting of a superconducting titanium nanobridge with niobium contacts. Present devices have T_{c}, = 0.3 K and a measured intrinsic energy resolution of approximately 6 terahertz fullwidth at half-maximum, near the predicted value due to intrinsic thermal fluctuation noise, with a time constant of 2Î¼is. An intrinsic energy resolution of 1 terahertz should be achievable by reducing the volume of the titanium nanobridge. Such a detector has important applications in future space-based terahertz astronomy missions. 2009 American Institute of Physics.},

We study three different quadruple points in the presence of a magnetic field and show that a trapped particle in one of the dot plays an essential role in determining the spin character of the transport. Many-electron states of the triple quantum dot molecules are used as transport channels in the Fermi's Golden Rule approach and it is demonstrated that the Aharonov-Bohm oscillations of the energy spectrum lead to spin-selective oscillations in transport. {\copyright} 2009 WILEY-VCH Verlag GmbH & Co.
