Tour de gross: A modular quantum computer based on bivariate bicycle codes
Theodore J. Yoder, Eddie Schoute, Patrick Rall +5
We present the bicycle architecture, a modular quantum computing framework based on high-rate, low-overhead quantum LDPC codes identified in prior work. For two specific bivariate…
Thermal State Preparation via Rounding Promises
Patrick Rall, Chunhao Wang, Pawel Wocjan
A promising avenue for the preparation of Gibbs states on a quantum computer is to simulate the physical thermalization process. The Davies generator describes the dynamics of an o…
Signed quantum weight enumerators characterize qubit magic state distillation
Patrick Rall
Many proposals for fault-tolerant quantum computation require injection of 'magic states' to achieve a universal set of operations. Some qubit states are above a threshold fidelity…
High-threshold and low-overhead fault-tolerant quantum memory
Sergey Bravyi, Andrew W. Cross, Jay M. Gambetta +3
Quantum error correction becomes a practical possibility only if the physical error rate is below a threshold value that depends on a particular quantum code, syndrome measurement…
Quantum Approximate Counting, Simplified
Scott Aaronson, Patrick Rall
In 1998, Brassard, Hoyer, Mosca, and Tapp (BHMT) gave a quantum algorithm for approximate counting. Given a list of items, of them marked, their algorithm estimates to…
Quantum-centric Supercomputing for Materials Science: A Perspective on Challenges and Future Directions
Yuri Alexeev, Maximilian Amsler, Paul Baity +124
Computational models are an essential tool for the design, characterization, and discovery of novel materials. Hard computational tasks in materials science stretch the limits of e…
