                     ULTIMATE GUIDE ON QUANTUM COMPUTING
INTRODUCTION
Quantum Computing is a new 
paradigm of algorithmic study which 
extends quantum mechanical 
phenomena to the world of 
traditional computing. 
In 1982, Richard Feynman proposed 
an initial quantum computer, which 
would have the capacity to facilitate 
traditional algorithms with quantum 
circuits.

ABOUT QUANTUM 
PHENOMENA
To understand systems of electrons 
and to navigate the multiple 
independent probabilities of electron 
location based on quantum 
phenomena, Feynman envisioned 
the concept of a quantum computer; 
he believed that quantum computers 
could ideally simulate quantum 
behavior as it would have occurred 
in nature.

WHAT ARE 
QUANTUM 
COMPUTERS?
Quantum Computing is the field that 
integrates quantum mechanical 
phenomena into a computing device. 
Quantum computers use properties 
like superposition and entanglement 
to perform computation.

HOW DO THEY 
WORK?
Quantum information is data for 
quantum states which is utilized for 
the study of computational 
manipulation. 
This quantum information is 
processed in the form of “qubits”. 
Qubits can be thought of as the 
computational analog for bits and 
are the fundamental units of 
information for quantum computing.

QUANTUM 
REGISTERS
In a quantum computer, quantum 
registers are simply considered to be 
systems of multiple qubits. It is the 
quantum analog of a classical 
computing register. All quantum 
calculations are performed by 
manipulating qubits within the 
register.

QUANTUM GATES
We know that classical computers 
manipulate bits through logic gates. 
Logic gates essentially transform the 
value that a bit holds. They are the 
building blocks of any digital system. 
Logic gates are used with truth 
tables to create transformations of 
state in classical circuits.

INSIDE A 
QUANTUM 
COMPUTER
The main component of the machine 
— the superconducting processor — 
consists of a transmon qubit (uses 
supercharge and maintains qubit 
control without noise) and Josephon 
junctions (allows supercharge to flow 
through the machine).

APPLICATIONS
Well, we know that quantum 
computers are great because of their 
properties like superposition and 
entanglement. However, it is 
important to realize that we live in a 
quantum world and that quantum 
computers will allow us to better 
simulate the behavior of nature, 
down to a molecular level.
