                  Today’s date, we are producing about 328.77 million terabytes 
of data per day, which represents the larger population of internet 
users who are continuously accessing and feeding data. Accordingly, it 
makes it challenging for classical computers to manage vast amounts of 
data and process faster. 
 
  With rigorous advancements in computing technologies, the technology Artificial Intelligence 
(AI) signifies the ability to process information by imitating human 
cognitive functions. It includes having learning abilities and 
problem-solving. Accordingly, mathematical modeling and logic are used 
to simulate humanlike reasoning abilities for learning and 
decision-making. 
 
  Machine learning 
applies AI using mathematical models of data for learning without human 
intervention. It helps to improve computer systems through continuous 
learning and gathering experiences. 
 
  AI entering in Businesses: 
 
  Artificial
 intelligence (AI) is being used as a supporting tool in business rather
 than a replacement for human intelligence. AI is adept at processing 
and analyzing vast amounts of data much faster than humans and can 
return synthesized courses of action to streamline the decision-making 
process. AI has a wider latitude of decision-making ability, making it 
highly valuable across many industries, such as machine learning, 
cybersecurity, customer relationship management, internet searches, and 
personal assistants. Machine learning is used in systems that capture 
vast amounts of data, while AI is an indispensable ally in looking for 
holes in computer network defenses. 
 
  AI
 is changing customer relationship management systems, making them 
self-updating and auto-correcting. Additionally, AI uses a vast amount 
of data to identify patterns in people's search behaviors and provide 
them with more relevant information. Finally, AI bots can be used as 
personal assistants to manage emails, calendars, and provide 
recommendations for streamlining processes, ultimately providing 
businesses with extra time to focus on implementing strategies to grow.
 
  Key roles:
 
  · Process automation.
 
  · Boosting speed and consistency of services 
 
  · Better-informed decision making 
 
  · Identify new opportunities 
 
  Advantages:
 
  · Improved Productivity
 
  · Improved Quality
 
  · Reduced Time
 
  · Reduced Costs
 
  · Improved Reliability
 
   
 
  Based
 on that, the exponential growth of data collection, particularly by 
tech giants like Facebook and Google, has resulted in massive amounts of
 data being available for user specific analysis. The availability of 
vast amounts of data and the rapid advancement in processor power and 
parallel computing has made it easier to acquire and analyze large 
volumes of data.
 
  In 
this context, complex correlational problems used for learning, and 
running realistic computer models to simulate real-world scenarios are 
computationally critical and challenging in classical computers. Machine
 learning is a stochastic process. Classical computers use the 
deterministic approach that needs a better way to improve ML (Machine 
Learning). Hence, using probabilistic systems could improve the overall 
ML and AI.  
 
   
 
  Why Quantum?
 
  Unique features -
 
  Quantum
 Computers operate on the principle of Quantum mechanics such as 
superposition, entanglement, and qubits for information processing and 
computations. The probabilistic (non-deterministic) nature of quantum 
computing makes it naturally perfect at solving certain complex l 
problems. It can improve machine learning models with faster 
computational power and better generalization power.
 
  Superposition
 allows a qubit to hold multiple values at once. On the other hand, 
entanglement allows multiple qubits to be interconnected in a way that 
expands problem-solving abilities. Programming quantum computers differs
 from programming classical computers. 
 
  In
 quantum programming, qubits are connected using quantum gates that 
operate on them, resembling electronic design. When algorithms are coded
 in quantum language, quantum computers can achieve significantly faster
 and exponential processing speeds compared to classical computers for 
specific problems.
 
  A 
study conducted by Google identifies that Quantum computers can 
effectively solve complex problems that classical computers struggle 
with due to intricate correlations between inputs. Accordingly, it 
suggests that learning models built on quantum computers are better at 
certain applications, resulting in faster computation and better 
generalization on less data. As a result, it is essential to determine 
the scenarios where such a "quantum advantage" can be attained. 
 
   
 
  Quantum Advantages (Computational Advantages)- 
 
  Heuristics Approach for AI/ML - 
 
  Quantum
 computing heuristic works differently than classical heuristic. Quantum
 Data incorporates Superposition and Entanglement that leads to joint 
probability distributions of states. As a result, it enables sampling 
from extremely complex probability distribution of Hilbert space. 
 
  It
 can create efficient models for Heuristic ML for maximizing extraction 
of classical information from noisy entangled data. Such developments 
can improve simulation on quantum devices for chemical simulation, 
Quantum Matter Simulation and Quantum Control.  
 
  Quantum Algorithms for accelerating computational processes -
 
  Quantum
 Algorithms have many sets of benefits such as exponential accelerations
 in solving linear system equations (HHL algorithm). Least-squares 
linear regression and Gaussian processes are solved at exponential 
computational speed using HHL algorithm.
 Additionally, Grover search algorithm allows efficient searches for 
speeding up over classical searches for bigger data sets. As data sets 
become more complex and larger, computing resources struggle to keep up.
 However, these Quantum algorithms can sample data and optimize faster 
than classical algorithms from a larger data set. Therefore, Quantum can
 accelerate the computational processes involved in AI/ML.
 
  Hybrid Quantum-Computing algorithms - 
 
  Combining
 Classical and Quantum processors is expected to deliver better 
performance in the near term to overcome noise issues and network 
connectivity limitations of Quantum Computers. For example, 
Quantum-Inspired Evolutionary Algorithm (QIEA), Variational Quantum 
Eigen Solver, and QAOA (Quantum Approximate Optimization Algorithm) can 
boost AI and ML performances significantly. 
 
  Quantum AI hybrids can 
 
  · Prepare Quantum Data sets 
 
  · Assess quantum neural network models for extracting hidden information for finding new Data patterns faster 
 
  · Evaluate cost functions
 
  · Integrate data from many data sets 
 
  Limitations of Using Quantum Computing for AI/ML
 
  Quantum
 algorithms and programming require different thought processes for 
overcoming hardware limitations such as noise, errors-corrections, qubit
 connectivity and fidelity. Therefore, effective programming platforms 
are needed along with high level programming expertise to achieve 
desired outcomes for AI/ML engineers. 
 
  For
 industrial customers, partnering with Quantum Computing enterprises can
 have strategic benefits. Accordingly, the initial steps to begin with 
are conducting early proof of concepts and identifying early use cases. 
It can reduce the knowledge and skills gap in Quantum Machine Learning 
and Artificial Intelligence for near-term and long-term benefits. This 
is necessary to avoid falling behind other organizations that have 
already mastered quantum machine learning and AI when the hardware and 
software eventually meet the enormous potential of quantum computing.
