Separability of very noisy mixed states and implications for NMR quantum computing
S. L. Braunstein, C. M. Caves, R. Jozsa +3
We give a constructive proof that all mixed states of N qubits in a sufficiently small neighborhood of the maximally mixed state are separable. The construction provides an explici…
Quantum Error Correction and Reversible Operations
Carlton M. Caves
I give a pedagogical account of Shor's nine-bit code for correcting arbitrary errors on single qubits, and I review work that determines when it is possible to maintain quantum coh…
Complete quantum teleportation using nuclear magnetic resonance
M. A. Nielsen, E. Knill, R. Laflamme
Quantum mechanics provides spectacular new information processing abilities (Bennett 1995, Preskill 1998). One of the most unexpected is a procedure called quantum teleportation (B…
On Sasakian-Einstein Geometry
Charles P. Boyer, Krzysztof Galicki
We discuss Sasakian-Einstein geometry under a quasi-regularity assumption. It is shown that the space of all quasi-regular Sasakian-Einstein orbifolds has a natural multiplication…
Cluster-subcluster Mergers and the Formation of Narrow-angle Tailed Radio Sources
M. Bliton, E. Rizza, J. O. Burns +2
We have examined the ROSAT PSPC X-ray properties of a sample of 15 Abell clusters containing 23 narrow-angle tailed (NAT) radio galaxies. We find that clusters with NATs show a sig…
BVRI Light Curves for 22 Type Ia Supernovae
Adam G. Riess, Robert P. Kirshner, Brian P. Schmidt +6
We present 1210 Johnson/Cousins B,V,R, and I photometric observations of 22 recent type Ia supernovae (SNe Ia): SN 1993ac, SN 1993ae, SN 1994M, SN 1994S, SN 1994T, SN 1994Q, SN 199…
The Eastern Arm of M83 Revisited: High-Resolution Mapping of 12CO 1-0 Emission
R. J. Rand, S. D. Lord, J. L. Higdon
We have used the Owens Valley Millimeter Array to map 12CO (J=1-0) along a 3.5 kpc segment of M83's eastern spiral arm at resolutions of 6.5"x3.5", 10", and 16". The CO emission in…
Search for a Technicolor omega_T Particle in Events with a Photon and a b-quark Jet at CDF
The CDF Collaboration, F. Abe
If the Technicolor omega_T particle exists, a likely decay mode is omega_T -> gamma pi_T, followed by pi_T -> bb-bar, yielding the signature gamma bb-bar. We have searched 85 pb^-1…
Measurement of the Top Quark Mass with the Collider Detector at Fermilab
F. Abe, CDF Collaboration
We present a new measurement of the top quark mass in events in which both bosons from top quarks decay into lepton (). We use events collected by the CDF exp…
Search for second generation leptoquarks in the dimuon plus dijet channel of p-pbar collisions at sqrt{s}=1.8 TeV
CDF collaboration, F. Abe
We report on a search for second generation leptoquarks (Phi_2) using a data sample corresponding to an integrated luminosity of 110 pb^{-1} collected at the Collider Detector at F…
Shifts on a finite qubit string: A class of quantum baker's maps
R. Schack, C. M. Caves
We present two complementary ways in which Saraceno's symmetric version of the quantum baker's map can be written as a shift map on a string of quantum bits. One of these represent…
Lattice Effective Actions and Light-Quark Confinement
K. Cahill, G. Herling
The positive-plaquette Manton action at weak coupling is a reasonable action for short-distance phenomena. We propose an iterative scheme for evolving this action into an effective…
Search for New Particles Decaying to b bbar in p pbar Collisions at sqrt{s}=1.8 TeV
F. Abe
We have used 87 pb^-1 of data collected with the Collider Detector at Fermilab to search for new particles decaying to b bbar. We present model-independent upper limits on the cros…
Measurement of the lepton charge asymmetry in W-boson decays produced in p-pbar collisions
F. Abe et. al, The CDF Collaboration
We describe a measurement of the charge asymmetry of leptons from W boson decays in the rapidity range 0<|y_l|<2.5 using W --> enu, munu events from 110+/-7 pb^{-1}of data collecte…
Density Operators for Fermions
Kevin E. Cahill, Roy J. Glauber
The mathematical methods that have been used to analyze the statistical properties of boson fields, and in particular the coherence of photons in quantum optics, have their counter…
New HI-detected Galaxies in the Zone of Avoidance
L. Staveley-Smith, S. Juraszek, B. S. Koribalski +8
We present the first results of a blind HI survey for galaxies in the southern Zone of Avoidance with a multibeam receiver on the Parkes telescope. This survey is eventually expect…
The disruption of nearby galaxies by the Milky Way
M. E. Putman, B. K. Gibson, L. Staveley-Smith +23
Interactions between galaxies are common and are an important factor in determining their physical properties such as position along the Hubble sequence and star-formation rate. Th…
Measurement of the Bs0 Meson Lifetime Using Semileptonic Decays
F. Abe
The lifetime of the Bs0 meson is measured using the semileptonic decay Bs0 --> Ds- l+ nu X. The data sample consists of about 110 pb^-1 of pp= collisions at sqrt{s} = 1.8 TeV colle…
A Possible Solution to the Tritium Endpoint Problem
G. J. Stephenson, T. Goldman
Scalar or right-chiral interaction currents may be expected to produce a neutrino coupled to the electron which is different from, and perhaps even orthogonal to, that coupled to t…

D0 Collaboration, B. Abbott
We have made a precise measurement of the central inclusive jet cross section at sqrt(s) = 1.8 TeV. The measurement is based on an integrated luminosity of 92 pb-1 collected at the…
