Constant-Time Quantum Search with a Many-Body Quantum System
Benjamin DalFavero, Alexander Meill, David A. Meyer +2
The optimal runtime of a quantum computer searching a database is typically cited as the square root of the number of items in the database, which is famously achieved by Grover's…
A spinor Bose-Einstein condensate phase-sensitive amplifier for SU(1,1) interferometry
J. P. Wrubel, A. Schwettmann, D. P. Fahey +6
The SU(1,1) interferometer was originally conceived as a Mach-Zehnder interferometer with the beam-splitters replaced by parametric amplifiers. The parametric amplifiers produce st…
Spinor dynamics in an antiferromagnetic spin-1 thermal Bose gas
Hyewon K. Pechkis, Jonathan P. Wrubel, Arne Schwettmann +4
We present experimental observations of coherent spin-population oscillations in a cold thermal, Bose gas of spin-1 sodium-23 atoms. The population oscillations in a multi-spatial-…
Glass-like two-level systems in minimally disordered mixed crystals
J. P. Wrubel, B. E. Hubbard, N. I. Agladze +5
THz spectroscopy is used to identify a broad distribution of two-level systems, characteristic of glasses, in the substitutional monatomic mixed crystal systems, Ba_{1-x}Ca_xF_2 an…
Controlled switching of intrinsic localized modes in a 1-D antiferromagnet
J. P. Wrubel, M. Sato, A. J. Sievers
Nearly steady-state locked intrinsic localized modes (ILMs) in the quasi-1d antiferromagnet (C2H5NH3)2CuCl4 are detected via four-wave mixing emission or the uniform mode absorptio…
