Over forty years of research towards the understanding of Quantum Brownian Motion -- the contributions of A. O. Caldeira
Marcus V. S. Bonança, Sebastian Deffner, Gert-Ludwig Ingold
This article presents a brief account of Amir O. Caldeira's contributions to the theory of quantum Brownian motion. Motivated by its importance, we outline the description of Brown…
Hybrid qubit-oscillator module from motional states of two interacting atoms
Jaeyong Hwang, Tianrui Xu, Sean R. Muleady +5
We propose a qubit-oscillator platform based on the motional states of two interacting atoms in an optical tweezer. By stroboscopically modulating an engineered trap with tunable a…
The Pound-Drever-Hall Method for Superconducting-Qubit Readout
Ibukunoluwa Adisa, Won Chan Lee, Kevin C. Cox +1
Scaling quantum computers to large sizes requires the implementation of many parallel qubit readouts. Here we present an ultrastable superconducting-qubit readout method using the…
Measurement-induced entanglement in noisy 2D random circuits
Zhi-Yuan Wei, Jon Nelson, Joel Rajakumar +4
We study measurement-induced entanglement (MIE) generated by column-by-column sampling of noisy 2D random circuits of size and depth . Focusing primarily on Clifford circuit…
Qudit low-density parity-check codes
Daniel J. Spencer, Andrew Tanggara, Tobias Haug +2
Qudits offer significant advantages over qubit-based architectures, including more efficient gate compilation, reduced resource requirements, improved error-correction primitives,…
Utility-Scale Quantum State Preparation: Classical Training using Pauli Path Simulation
Cheng-Ju Lin, Hrant Gharibyan, Vincent P. Su
We use Pauli Path simulation to variationally obtain parametrized circuits for preparing ground states of various quantum many-body Hamiltonians. These include the quantum Ising mo…
