Nearly optimal polynomial approximations for the quantum singular value transform
Evan Rule
The paper presents simple Chebyshev‑based polynomial approximations of even and odd step functions on [-1,1] that achieve nearly optimal error, and shows how these can be employed…
Revisiting Turner Window Axions: The Untapped Potential of NaI Dark Matter Detectors
W. C. Haxton, Xing Liu, Anupam Ray +1
The "Turner window" corresponds to axions with masses 1 eV that have sufficiently strong couplings to matter to evade limits from the cooling of SN1987A. This window, thr…
A time-dependent wave-packet approach to reactions for quantum computation
Evan Rule, Ionel Stetcu
We describe a method for obtaining the scattering matrix for nuclear or chemical reactions on a finite lattice. Aside from the preparation of the initial and final states as wave p…
CaRBM: A Fixed-Depth Quantum Algorithm with Partial Correction for Thermal State Preparation
Omar Alsheikh, A. F. Kemper, Ermal Rrapaj +2
We introduce the CaRBM algorithm for fixed-depth thermal state preparation. Our algorithm is based on thermal state purification and uses the Restricted Boltzmann Machine (RBM) blo…
Recursive algorithm for constructing antisymmetric fermionic states in first quantization mapping
E. Rule, I. A. Chernyshev, I. Stetcu +2
We devise a deterministic quantum algorithm to produce antisymmetric states of single-particle orbitals in the first quantization mapping. Unlike sorting-based antisymmetrization a…
Is the Turner Window Open? Seeking Closure with Resonant Absorption of Galactic Axions in NaI Dark Matter Detectors
W. C. Haxton, Xing Liu, Anupam Ray +1
Motivated by the DAMA/LIBRA annual modulation signal, the dark matter community has invested heavily in ultra-clean underground NaI detectors to search for light WIMPs. We point ou…
