Entangling gate performance and fidelity limits with neutral atom Förster resonances
S. A. Norrell, Y. Shen, M. Saffman +1
Neutral-atom entangling gates are commonly analyzed with a single effective Rydberg-pair state, but near Förster resonances the pair manifold contains resonantly coupled interactio…
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…
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…
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…
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…
