Quantum Computing

Quantum mechanics, the subfield of physics that describes the behavior of very small (quantum) particles, provides the basis for a new paradigm of computing. First proposed in the 1980s as a way to improve computational modeling of quantum systems, the field of quantum computing has recently garnered significant attention due to progress in building small-scale devices. However, significant technical advances will be required before a large-scale, practical quantum computer can be achieved.Quantum Computing: Progress and Prospects provides an introduction to the field, including the unique characteristics and constraints of the technology, and assesses the feasibility and implications of creating a functional quantum computer capable of addressing real-world problems. This report considers hardware and software requirements, quantum algorithms, drivers of advances in quantum computing and quantum devices, benchmarks associated with relevant use cases, the time and resources required, and how to assess the probability of success.Table of ContentsFront MatterSummary1 Progress in Computing2 Quantum Computing: A New Paradigm3 Quantum Algorithms and Applications4 Quantum Computing's Implications for Cryptography5 Essential Hardware Components of a Quantum Computer6 Essential Software Components of a Scalable Quantum Computer7 Feasibility and Time Frames of Quantum ComputingAppendixesAppendix A: Statement of TaskAppendix B: Trapped Ion Quantum ComputersAppendix C: Superconducting Quantum ComputersAppendix D: Other Approaches to Building QubitsAppendix E: Global R&D InvestmentAppendix F: Committee and Staff Biographical InformationAppendix G: Briefers to the CommitteeAppendix H: Acronyms and AbbreviationsAppendix I: Glossary
