Learn to write algorithms and program in the new field of quantum computing. This second edition is updated to equip you with the latest knowledge and tools needed to be a complex problem-solver in this ever-evolving landscape. The book has expanded its coverage of current and future advancements and investments by IT companies in this emerging technology. Most chapters are thoroughly revised to incorporate the latest updates to IBM Quantum's systems and offerings, such as improved algorithms, integrating hardware advancements, software enhancements, bug fixes, and more.

Youll examine quantum computing in the cloud and run experiments there on a real quantum device. Along the way youll cover game theory with the Magic Square, an example of quantum pseudo-telepathy. Youll also learn to write code using QISKit, Python SDK, and other APIs such as QASM and execute it against simulators (local or remote) or a real quantum computer. Then peek inside the inner workings of the Bell states for entanglement, Grovers algorithm for linear search, Shors algorithm for integer factorization, and other algorithms in the fields of optimization, and more. Finally, youll learn the current quantum algorithms for entanglement, random number generation, linear search, integer factorization, and others.

By the end of this book, youll understand how quantum computing provides massive parallelism and significant computational speedups over classical computers
