Write algorithms and program in the new field of quantum computing. This
book covers major topics such as the physical components of a quantum
computer: qubits, entanglement, logic gates, circuits, and how they
differ from a traditional computer. Also, Practical Quantum Computing
for Developers discusses quantum computing in the cloud using IBM Q
Experience including: the composer, quantum scores, experiments,
circuits, simulators, real quantum devices, and more. You'll be able to
run experiments in the cloud on a real quantum device.
Furthermore, this book shows you how to do quantum programming using the
QISKit (Quantum Information Software Kit), Python SDK, and other APIs
such as QASM (Quantum Assembly). You'll learn to write code using these
languages and execute it against simulators (local or remote) or a real
quantum computer provided by IBM's Q Experience. Finally, you'll learn
the current quantum algorithms for entanglement, random number
generation, linear search, integer factorization, and others. You'll
peak inside the inner workings of the Bell states for entanglement,
Grover's algorithm for linear search, Shor's algorithm for integer
factorization, and other algorithms in the fields of optimization, and
more.
Along the way you'll also cover game theory with the Magic Square, an
example of quantum pseudo-telepathy where parties sharing entangled
states can be observed to have some kind of communication between them.
In this game Alice and Bob play against a referee. Quantum mechanics
allows Alice and Bob to always win!
By the end of this book, you will understand how this emerging
technology provides massive parallelism and significant computational
speedups over classical computers, and will be prepared to program
quantum computers which are expected to replace traditional computers in
the data center.
What You Will Learn
