Nobel Laureate George Smoot has been appointed director of a new cosmology institute in South Korea that will work closely with the year-old Berkeley Center for Cosmological Physics to explore the origin and fate of the universe.

Cal senior center Alex Mack was named winner of the 2008 Draddy Trophy as the nation's top football scholar-athlete during a ceremony in New York Tuesday night. The Draddy Trophy, also referred to as the "Academic Heisman," is one of

Two winning streaks will be on the line tonight at the Marriott Center as the 8-0 BYU men's basketball team hosts the 6-1 Boise State Broncos.

The BYU women's basketball (5-2) team will take on Weber State (3-4) tonight at 5 p.m. in the Marriott Center.

We consider the ideal situation in which a space rotation is transferred froma quantum spin j to a quantum spin l different from j. Quantum-informationtheoretical considerations lead to the conclusion that such operation ispossible only for l not greater than

We give a one-dimensional quantum cellular automaton (QCA) capable ofsimulating all others. By this we mean that the initial configuration and thelocal transition rule of any one-dimensional QCA can be encoded within theinitial configuration of the universal QCA. Several steps

A central challenge for implementing quantum computing in the solid state isdecoupling the qubits from the intrinsic noise of the material. We investigatethe implementation of quantum gates for a paradigmatic, non-Markovian model: Asingle qubit coupled to a two-level system that

We show that the strength of non-commutativity could play a role indetermining the boundary condition of a physical problem. As a toy model weconsider the inverse square problem in non-commutative space. The scaleinvariance of the system is known to be

In an experiment using the odd calcium isotope 43Ca+ we combine the merits ofa high fidelity entangling operation on an optical transition (optical qubit)with the long coherence times of two 'clock' states in the hyperfine groundstate (hyperfine qubit) by mapping

We present a unified formulation for quantum statistical physics based on therepresentation of the density matrix as a functional integral. We identify thestochastic variable of the effective statistical theory that we derive as aboundary configuration and a zero mode relevant

Many quantum key distribution (QKD) implementations using a free spacetransmission path are restricted to operation at night time in order todistinguish the signal photons used for a secure key establishment frombackground light. Here, we present a lean entanglement-based QKD systemovercoming

A certain modification of the semiclassical quantization condition based onthe summarization of the known power expansion in the squared Planck constantis proposed. Corresponding deviation from exact spectra arises only togetherwith the deviation of the studied potential from the supersymmetric one

We study the possibility of giving a classical interpretation to quantumprojective measurements for a particle described by a pure Gaussian state whoseWigner function is non-negative. We analyze the case of a projectivemeasurement which gives rise to a proper Wigner function,

We provide an exact and complete characterization of the entanglementdynamics of two qubits coupled to a common structured reservoir at zerotemperature. We derive the conditions to maximize reservoir-inducedentanglement for an initially factorized state of the two-qubit system. Inparticular, when the

We present an overview of the validity of the Proximity Force Approximation(PFA) in the calculation of Casimir forces between perfect conductors fordifferent geometries, with particular emphasis for the configuration of acylinder in front of a plane. In all cases we

A transcoordinate physics is introduced in a previous paper. It is found thatthe transcoordinate state of a system cannot be defined along a plane inMinkowski space, so a new nonplanar definition of state is proposed in whichthe notion of simultaneity

In a recent Letter [Phys. Rev. Lett. 99, 170502 (2007); quant-ph/0703227],Chandran and coworkers study the entanglement properties of valence bond (VB)states. Their main result is that VB states do not contain (or only aninsignificant amount of) two-site entanglement, whereas they

We study the influence of thermal Casimir-Polder forces on the near-surfacetrapping of cold polar molecules, with emphasis on LiH and YbF near an Ausurface at room temperature. We show that for a molecule initially prepared inits electronic and rovibrational ground

We design extremely flexible ultrahigh-Q diamond-based double-heterostructurephotonic crystal slab cavities by modifying the refractive index of thediamond. The refractive index changes needed for ultrahigh-Q cavities with $Q ~10^7$, are well within what can be achieved ($\Delta n \sim 0.02$). The
