2. What is QUANTUM
COMPUTING ?
Quantum computing is an area of computer
science that uses the principles of quantum
theory. Quantum theory explains the behavior of
energy and material on the atomic and subatomic
levels.
Quantum computing uses subatomic particles,
such as electrons or photons. Quantum
computing has the capability to sift through huge
numbers of possibilities and extract potential
solutions to complex problems and challenges.
Where classical computers store information as
bits with either 0s or 1s, quantum computers use
qubits

Quantum computers use quantum bits or qubits, which can exist in multiple states simultaneously due to
superposition. Classical computers use classical bits that can only represent either 0 or 1.
Qubits can exist in a superposition of states, which means they can represent both 0 and 1 at the same
time. This allows quantum computers to explore multiple possibilities in parallel.
Qubits can be entangled, meaning the state of one qubit is dependent on the state of another, regardless of
the distance between them.
Quantum computers use quantum gates to manipulate qubits. These gates can perform operations on
qubits in superposition, taking advantage of quantum properties to perform calculations.
Quantum computers use specialized quantum algorithms to solve certain problems more efficiently than
classical algorithms.

4. According to IBM, it's
what a qubit can do
rather than what it is
that's remarkable. A
qubit places the
quantum information
that it contains into a
state superposition.
Entanglement it is
integral to quantum
computing power.
Pairs of qubits can be
made to become
entangled. This means
that the two qubits
then exist in a single
state.
Decoherence occurs
when the quantum
behavior of qubits
decays. The quantum
state can be disturbed
instantly by vibrations
temperature changes.

have the potential to
provide exponential

they can efficiently
factor large numbers.

GOOGLE is spending billions of dollars to build its
quantum computer by 2029. The company opened a
campus in California called Google AI to help it meet this
goal.
IBM plans to have a 1,000-qubit quantum computer in
place by 2023. For now, IBM allows access to its
machines for those research organizations.
MICROSOFT offers companies access to quantum
technology via the Azure Quantum platform.
OTHERS There’s interest in quantum computing and its

7. Three types of Quantum
computing
Quantum computing encompasses several different types of technologies and platforms
that leverage the principles of quantum mechanics to perform computational tasks. Here
are some of the main types of quantum computing:

Superconducting
Qubits

Quantum
Computers
Topological Qubits
Superconducting qubits
are one of the most widely
used types of qubits in
quantum computing. They
are tiny circuits made from
superconducting materials
that can carry electrical
current
Trapped ion quantum
computers use ions (usually
trapped in electromagnetic
fields) as qubits. These
qubits are manipulated
using lasers. Companies like
Ion and Honeywell are
actively working.
Topological qubits are a
relatively new approach to
quantum computing. They
are based on the concept
of topological quantum
states that are highly
robust against errors.

Quantum Computing in
Industry
Quantum computing has the potential to revolutionize various industries by offering the
capability to solve complex problems much faster than classical computers.
10. Quantum Computing vs. Classical
Computing
• Uses qubits that can exist in a superposition of
states, representing both 0 and 1 simultaneously.
• Utilizes quantum gates to manipulate qubits,
exploiting superposition and entanglement
properties.
• Leverages superposition, allowing qubits to
represent multiple states simultaneously.
• Qubits can become entangled, where the state of
one qubit depends on the state of another, even
when separated.
Quantum
Computing
Classical
Computing
• Uses classical bits (0 or 1) as the fundamental unit of
information.
• Operates on classical bits using logic gates that
manipulate bits based on Boolean logic.
• Does not have a superposition property; each bit is in
either state 0 or 1.
• Classical bits are independent and not entangled with
each other.
11. What are the applications of quantum
computing ?
The quantum computer is able to crunch enormous data, which includes molecular activity in one being. This ability enables
the computer to create very accurate simulations of real life events, such as photosynthesis.
Instead of calculating a problem at a time, this computing approach solves various probabilities. Through such a system, you can
see how each option can provide the most advantages. Thus, you can optimize that option
Cryptography involves difficult mathematical problems such as discrete algorithms and integer factorization. These
problems take a long time to solve. However, a computer with quantum principles can do it quickly
Although the conventional computer has evolved so much over the past decades, data search still takes too long sometimes.
Quantum principles are capable of speeding up this data search process, especially if the search is unstructured.
