This book offers an introduction to quantum technology that is specifically tailored to economists, students of economics, and professionals in the financial and payments industries. The book reviews quantum speedups that have been identified for algorithms used to solve and estimate economic models, including function approximation, linear systems analysis, graphical modeling, Monte Carlo simulation, matrix inversion, principal component analysis, linear regression, dynamic programming, interpolation, numerical differentiation, and true random number generation. It also provides an overview of quantum financial technology and its potential applications in economics and finance. Written by an interdisciplinary team with backgrounds in economics, computer science, and physics, this book offers a valuable guide for researchers and practitioners who want to understand the implications and possibilities of quantum technology for the field of economics.

This book reveals glimpses of how the quantum physics of atoms and molecules influences, and even controls, the way our cells function and how we and our fellow animals interact with our environment. Simply put, how birds fly and why grass grows. Certainly, biochemistry and molecular biology are the foundations for the biology of living cells, but there is more—quantum coherence and entanglement influencing the functioning of proteins and enzymes, and strictly speaking, without the quantum phenomena we wouldn’t even be here. In the end, however, this book is based on the solid ground of science, presenting the many fascinating phenomena of how quantum physics makes life possible without any unwarranted mystification.

Våra kroppar är uppbyggda av biljoner mikroskopiska celler, och i cellernas innersta värld gäller kvantfysikens lagar. Kvantfysiken beskriver hur fåglarna hittar hem över tusentals kilometer och hur en ödla kan hänga upp och ner i taket. Kvantfysiken förklarar också fotosyntesen som är grunden för allt liv på jorden den process som ger en maskros kraften att spränga genom asfalten. I kvantfysikens värld kan en partikel befinna sig på många ställen vid samma tidpunkt. Den kan förflytta sig genom att välja alla vägar mellan två punkter - samtidigt. Och information kan se ut att färdas över stora avstånd utan att det tar någon tid alls. I den mikroskopiska världen kan det se ut som att naturens lagbundenhet faller samman till osäkerhet och slump bara genom att man tittar på den. Men det är faktiskt inte sant den följer bara andra lagar: kvantfysikens skenbart paradoxala vägar i atomernas och molekylernas värld. Kvantfysiken är också nyckeln till att förstå den genetik och biokemi som till slut förklarar hur vår kropp och vårt medvetande fungerar och kan påverkas. Kunskapen om kvantfysikens betydelse för medicin och biologi kan göra det möjligt att diagnosticera och behandla sjukdomar på nya sätt, och kanske i framtiden besvara de verkligt svåra frågorna hur uppstod och utvecklades livet på jorden?
