The field of quantum computing has grown rapidly in the two years since the
printings in its first year which mirrors the growing number of individuals
ramping up in the sector. I would like to thank all the faculty, students and
other readers from so many countries who provided helpful input for this new
edition.
Our world, of course, changed in many other ways as well since the
publication of the first edition. The global pandemic impacted all areas
of society and will probably transform how we work together for years to
come. While in-person meetings were halted, quantum tech researchers and
engineers found ways to continue their collaborations online.
In the last year, many countries have announced new or expanded quantum
tech initiatives. These programs are injecting significant resources into the
quantum tech ecosystem. We have also noted the rise in private investment in
the sector – both in quantum computing hardware companies as well as various
applications startups. All this activity has sharply increased the demand for
individuals who are trained in quantum computing as well as those with
additional hands-on experience in coding for these machines. This, in turn,
has led many universities to launch and expand their quantum information
science curricular programs and for corporations to start quantum tech training
programs for their teams.
With this new edition I continue to strive towards the goal of making
quantum computing more accessible to a wider range of individuals. This is
a technical book, but one that I hope opens the door to quantum computing
for individuals who would like to get a rigorous grasp of how to make these
novel computing devices work and which kinds of problems we should focus
on when using these platforms.
