Partially Fault-Tolerant Quantum Computation for Megaquop Applications
Ming-Zhi Chung, Ali H. Z. Kavaki, Artur Scherer +14
Partially fault-tolerant quantum computing (FTQC) has recently emerged as a promising approach for the execution of megaquop-scale circuits with millions of logical operations. In…
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…
Impacts of Decoder Latency on a Utility-Scale Quantum Computer Architecture
Abdullah Khalid, Allyson Silva, Gebremedhin A. Dagnew +10
The speed of a fault-tolerant quantum computer depends in large part on the reaction time of its classical electronics, that is, the total time required by decoders and controllers…
Optimizing Multi-level Magic State Factories for Fault-Tolerant Quantum Architectures
Allyson Silva, Artur Scherer, Zak Webb +11
We propose a novel technique for optimizing a modular fault-tolerant quantum computing architecture, taking into account any desired space-time trade-offs between the number of phy…
Multi-qubit Lattice Surgery Scheduling
Allyson Silva, Xiangyi Zhang, Zak Webb +7
Fault-tolerant quantum computation using two-dimensional topological quantum error correcting codes can benefit from multi-qubit long-range operations. By using simple commutation…
