Effective out-of-plane g-factor in strained-Ge/SiGe quantum dots
Andrew J. Miller, Mitchell Brickson, Will J. Hardy +6
Recently, lithographic quantum dots in strained-Ge/SiGe have become a promising candidate for quantum computation, with a remarkably quick progression from demonstration of a quant…
Atomic Precision Advanced Manufacturing for Digital Electronics
Daniel R. Ward, Scott W. Schmucker, Evan M. Anderson +8
An exponential increase in the performance of silicon microelectronics and the demand to manufacture in great volumes has created an ecosystem that requires increasingly complex to…
The Road to Useful Quantum Computers
Timothy Proctor, Robin Blume-Kohout, Andrew Baczewski
Building a useful quantum computer is a grand science and engineering challenge, currently pursued intensely by teams around the world. In the 1980s, Richard Feynman and Yuri Manin…
Spectral Deconvolution without the Deconvolution: Extracting Temperature from X-ray Thomson Scattering Spectra without the Source-and-Instrument Function
Thomas Gawne, Alina Kononov, Andrew Baczewski +7
X-ray Thomson scattering (XRTS) probes the dynamic structure factor of the system, but the measured spectrum is broadened by the combined source-and-instrument function (SIF) of th…
Impact of Electronic Correlations on High-Pressure Iron: Insights from Time-Dependent Density Functional Theory
Kushal Ramakrishna, Mani Lokamani, Andrew Baczewski +2
We present a comprehensive investigation of the electrical and thermal conductivity of iron under high pressures at ambient temperature, employing the real-time formulation of time…
QMCPACK : An open source ab initio Quantum Monte Carlo package for the electronic structure of atoms, molecules, and solids
Jeongnim Kim, Andrew Baczewski, Todd D. Beaudet +45
QMCPACK is an open source quantum Monte Carlo package for ab-initio electronic structure calculations. It supports calculations of metallic and insulating solids, molecules, atoms,…
Electrical Conductivity of Iron in Earth's Core from Microscopic Ohm's Law
Kushal Ramakrishna, Mani Lokamani, Andrew Baczewski +2
Understanding the electronic transport properties of iron under high temperatures and pressures is essential for constraining geophysical processes. The difficulty of reliably meas…
Quantifying -gate-count improvements for ground-state-energy estimation with near-optimal state preparation
Shivesh Pathak, Antonio Russo, Stefan Seritan +1
We study the question of when investing additional quantum resources in preparing a ground state will improve the aggregate runtime associated with estimating its energy. We analyz…
First-principles modeling of plasmons in aluminum under ambient and extreme conditions
Kushal Ramakrishna, Attila Cangi, Tobias Dornheim +2
The theoretical understanding of plasmon behavior is crucial for an accurate interpretation of inelastic scattering diagnostics in many experiments. We highlight the utility of lin…
