In the first line of his foreword, computer cryptography expert Alex Sharpe offers kudos to Anna Murray for this book and well he should.
To many, the term Quantum Computing, is an unknown definition. “What is it?” “What is different?” “ How will it affect daily life and business?” The word Quantum has become a buzz word for something large, usually complex, often with overtones of either science fiction or physics principles incomprehensible to those outside the field. Not to worry, Quantum Computing 101 is neither novel nor text. On the contrary, it is a succinct “A to Z” guide to the subject, with descriptions and definitions, a guide to what QC will do and what is necessary to prepare for the challenges and threats it will bring.
Based on her decades of experience in the computer field, Murray describes the concept without prolonged technical details then explores applications for the new concept which is an approach fundamentally different from established concepts of systems of today. It will not displace the present tasks of computers, rather it will make practical the rapid solution of complex problems with numerous interrelated variables. A few examples are those of accurate weather forecasts, composition and design of new materials, and especially the complex multiple variables in the development of new drugs. Inevitably there will be applications that are unimaginable today. When PCs were introduced, who thought of banking or checking on your babysitter from your phone? There are possibilities for a hybrid computer system that will blend quantum systems with traditional technologies. Finally, QC is not AI though quantum systems will relate to it.
With the potential stated, next comes concern. First is security for QC will have the ability to break the standard security protocols. That concern is for the present as well as the future. Data collected now, though encrypted; could be read when QC systems become available. Security issues are explored by an extensive delineation of the possibilities to resolve issues and prevent security breaches. Preparation for QC must be in place before its arrival and in that area, complacency may be the greatest threat.
As with any problem created by technological breakthroughs, new opportunities appear. In this instance, there will be opportunities to improve security to an extent not now possible. Throughout history it has been the new pioneers, unencumbered by past practices, that take charge and lead the change. QC systems and components should be no different whether hardware or software. Readers, especially those familiar with the issues will find descriptions of the leading companies useful.
But what of the timelines for change, especially internationally? Basic techniques and standards must be agreed upon internationally or the present system of world finance and trade will disintegrate – not over time but immediately with the first arrival of QC. The closing chapters explore the concept with regard to national leadership both in the U.S. and abroad, a most vital concern as the “window” of preparedness closes.
It is impossible to predict in detail, the sequence of the invasion of QC, nor the depth of its initial penetration, this is book is a vital guide. In summary, anyone in the management or operation of data systems needs this book. Those not in such positions still need awareness of the issue in order to heed its commentary and recommendations.
