We describe the design for a solid-state quantum computational architecture based on the integration of GHz-frequency mechanical resonators with Josephson phase qubits, which have the potential for demonstrating a variety of singleand multi-qubit operations critical to quantum computation. The computational qubits are eigenstates of large-area, current-biased Josephson junctions. Two or more qu...

We derive the equations of relativistic quantum mechanics from a modified version of classical electrodynamics, where probability is replaced by potential. As a result, a particle is not a localized entity, in the classical sense, but has a localized energy extremum. The particle/wave aspect of matter is inherent in the particle/wave equation describing elementary particles. Furthermore, the He...

academic) This thesis experimentally studies quantum interference phenomena and quantum coherence in mesoscopic systems, and quantum transport as well as magnetotransport in various materials system. One overarching aim is exploring the different mechanisms that give rise to quantum phase decoherence in lithographically patterned mesoscopic structures, of importance in the field of quantum tech...

Arbitrary quantum states cannot be copied. In fact, to make a copy we must provide complete information about the system. However, can a quantum system self-replicate? This is not answered by the no-cloning theorem. In the classical context, Von Neumann showed that a ‘universal constructor’ can exist which can self-replicate an arbitrary system, provided that it had access to instructions for m...

We review and study the roles of quantum and classical fluctuations in recent cavity-optomechanical experiments which have now reached the quantum regime (mechanical phonon occupancy .1) using resolved sideband laser cooling. In particular, both the laser noise heating of the mechanical resonator and the form of the optically transduced mechanical spectra, modified by quantum and classical lase...

A continuum ®nite element technique is adopted to study electronic properties of submicron electronic devices where function hinges on quantum mechanical e€ects. Of particular interest is the in ̄uence of mechanical strain on con®ned electronic states. The steady state Schr odinger equation, which governs the electronic behavior of such devices, is modi®ed to include the potential induced by a ...

this study is about complexes of li doped silicon carbide nanotube with thymine and cytosine ingas phase and aqueous solutions. li doped silicon carbide nanotube and its pyrimidine nucleobasecompounds were first modeled by quantum mechanical calculations in gas phase and in water.calculated binding energies indicated the stronger ability of thymine to functionalize silicon carbidenanotube than ...

Several studies in quantum mechanics and statistical mechanics have formally established that nonflat metrics induce a difference in the potential used to define the path-integral Lagrangian from that used to define the differential Schr̈odinger Hamiltonian. A recent study has described a statistical mechanical biophysical system in which this effect is large enough to be measurable. This study ...
