Absorbing Many-Body Correlations into Core-Optimized Orbitals
Hao Zhang, Matthew Otten
The cost of simulating quantum many-body systems - on classical or quantum hardware - scales with the number of variational parameters, so progress at fixed computational budget hi…
CANOE: Classically Assisted Non-Orthogonal Eigensolver
Jihyeon Park, Collin C. D. Frink, Matthew Otten
In the early fault-tolerant regime, where quantum resources remain limited, hybrid quantum-classical strategies offer one possible route toward quantum advantage. We introduce CANO…
Energy-Scaled Zero-Noise Extrapolation for Gottesman-Kitaev-Preskill Code
Gui-Zhong Luo, Matthew Otten
The performance of Gottesman-Kitaev-Preskill (GKP) codes, an approach to hardware-efficient quantum error correction, is limited by the finite squeezing capabilities of current exp…
Achieving Utility-Scale Applications through Full Stack Co-Design of Fault Tolerant Quantum Computers
Katerina Gratsea, Matthew Otten
Quantum computing promises revolutionary advances in modeling materials and molecules. However, the up-to-date runtime estimates for utility-scale applications on certain quantum h…
From Random Determinants to the Ground State
Hao Zhang, Matthew Otten
Accurate quantum many-body calculations often depend on reliable reference states or good human-designed ansätze, yet these sources of knowledge can become unreliable in hard probl…
Physics-Informed Neural Networks for Gate Design using Quantum Optimal Control
Sofiia Lauten, Matthew Otten
Implementing quantum gates on quantum computers can require the application of carefully shaped pulses for high-fidelity operations. We explore the use of physics-informed neural n…
Efficient algorithms for quantum chemistry on modular quantum processors
Tian Xue, Jacob P. Covey, Matthew Otten
Quantum chemistry is a promising application of future quantum computers, but the requirements on qubit count and other resources suggest that modular computing architectures will…
How to Build a Quantum Supercomputer: Scaling from Hundreds to Millions of Qubits
Masoud Mohseni, Artur Scherer, K. Grace Johnson +48
In the span of four decades, quantum computation has evolved from an intellectual curiosity to a potentially realizable technology. Today, small-scale demonstrations have become po…
Architecture for fast implementation of qLDPC codes with optimized Rydberg gates
C. Poole, T. M. Graham, M. A. Perlin +2
We propose an implementation of bivariate bicycle codes (Nature {\bf 627}, 778 (2024)) based on long-range Rydberg gates between stationary neutral atom qubits. An optimized layout…
Simulating Neutral Atom Quantum Systems with Tensor Network States
James Allen, Matthew Otten, Stephen Gray +1
In this paper, we describe a tensor network simulation of a neutral atom quantum system under the presence of noise, while introducing a new purity-preserving truncation technique…
