Overview of this book

Navigate the quantum computing spectrum with this book, bridging the gap between abstract, math-heavy texts and math-avoidant beginner guides. Unlike intermediate-level books that often leave gaps in comprehension, this all-encompassing guide offers the missing links you need to truly understand the subject. Balancing intuition and rigor, this book empowers you to become a master of quantum algorithms. No longer confined to canned examples, you'll acquire the skills necessary to craft your own quantum code. Quantum Computing Algorithms is organized into four sections to build your expertise progressively. The first section lays the foundation with essential quantum concepts, ensuring that you grasp qubits, their representation, and their transformations. Moving to quantum algorithms, the second section focuses on pivotal algorithms — specifically, quantum key distribution and teleportation. The third section demonstrates the transformative power of algorithms that outpace classical computation and makes way for the fourth section, helping you to expand your horizons by exploring alternative quantum computing models. By the end of this book, quantum algorithms will cease to be mystifying as you make this knowledge your asset and enter a new era of computation, where you have the power to shape the code of reality.

Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “In the second cell, type print(x), and then press Shift+Enter.

A block of code is set as follows:

circ = QuantumCircuit(2, 1)circ.h(1)
circ = get_oracle(circ, function)
circ.measure(0, 0)
display(circ.draw('latex'))

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

device = provider.get_backend('ibmq_qasm_simulator')job = execute(circuit, backend=device, shots=1000)
print(job.job_id())
result = job.result()
counts = result.get_counts(circuit)$

Any command-line input or output is written as follows:

$ mkdir quantum$ cd quantum

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “In Figure 8.30, the alice and bob qubit checks to see whether both Alice and Bob get their wishes.”
