Decoherence-Free Subspaces in Supersymmetric Oscillator Networks
Jeffrey Satinover
Quantum superpositions can be used for parallel information processing, but only if protected against decoherence. A two-particle four-state system may have two-dimensional subspac…
Quantum-Limited Measurement and Information in Mesoscopic Detectors
A. A. Clerk, S. M. Girvin, A. D. Stone
We formulate general conditions necessary for a linear-response detector to reach the quantum limit of measurement efficiency, where the measurement-induced dephasing rate takes on…
Randomized protocols for asynchronous consensus
James Aspnes
The famous Fischer, Lynch, and Paterson impossibility proof shows that it is impossible to solve the consensus problem in a natural model of an asynchronous distributed system if e…
Fractionalized Fermi liquids
T. Senthil, Subir Sachdev, Matthias Vojta
In spatial dimensions d >= 2, Kondo lattice models of conduction and local moment electrons can exhibit a fractionalized, non-magnetic state (FL*) with a Fermi surface of sharp ele…
The Shape of Nereid's Phase Function Changed From 1998 To 1999 and 2000
Bradley E. Schaefer, Suzanne W. Tourtellotte
We present well-sampled light curves of Nereid for 1999 and 2000 which show symmetric shapes centered on opposition as is characteristic of a large opposition surge. Surprisingly,…
Scratching the Bose surface
Subir Sachdev
This is a `News and Views' article discussing recent proposals for ground states of many boson systems which are neither superfluids nor Mott insulators.
