Brief Overview – Quantum Computing

Quantum Computing is the development of computer technology based on principles of quantum theory. It increases our reach to solve the problems of various fields using algorithms. The power of quantum computing arises from probabilistic computation, superposition, and entanglement.

Quantum theory developed on mathematician Peter Shor’s quantum algorithm calculates prime factors of extremely large numbers with utmost accuracy.

Speed is the key to our future systems, what can you expect with this technology is an instantaneous result to your search query. E.g., you ask for the top 10 best investable shares in 2020 say in the Pharmaceutical sector. It will check for top 10 shares, Pharma companies, and everything done simultaneously not step by step.

Researchers are concentrating efforts on leveraging the capabilities of quantum processors. Let’s assume it will reduce the time taken for performing tasks, response time, and accelerate work as compared to classical computers.

Types of Quantum Computing:

A quantum computer uses qubits also known as quantum bits.

Quantum Computing
  • Universal Quantum: Uniting Shors’ algorithm for factoring numbers, Grover’s algorithm for quick search in unstructured data, and many more algorithms needed to build a universal quantum computer.
  • Quantum Simulation: Simulators are software programs to test and run quantum algorithms/programs on classical computers.
  • Quantum Annealing: It focuses on finding the best possible configuration among the most possible combinations of variables. It can successfully reduce the air or land traffic; provide the best routing to save time, costs, and fuel. Huge benefits for airlines, logistics companies.

Quantum Mechanics and its relation with Quantum Computing:

The application of technology will depend on the quantum mechanical phenomena. Quantum computing is based on the study of how we can amalgamate information science and technology. The interpretations of probability theory impact the role of measurement in quantum mechanics.

Effect of Quantum Measurement in Quantum Computing:

It adds to the freedom of treating the problem by superposition and entanglement empowering a quantum computer to process limitless calculations simultaneously.

Entanglement in Quantum Computing:

It is a phenomenon of quantum mechanics, which is about the ability of two or multiple quantum particles to entangle. The application of any process on a particle will not be limited to that particular quantum particle instead applies to entangled particles.

Superposition in Quantum Computing:

Qubits can exemplify plentiful combinations of 1 and 0 at the same time. The ability to be in multiple states is known as superposition.

How does Quantum Computing add power to decision making?

Quantum computers can solve complex problems and provide solutions that classic computers cannot offer. Traditional computers cannot handle the enormous data generated all over the globe by millions of users. Continuous investment in new technology is a challenge but a need of time. Availability of everything online demands speed, agility, and ingenuity.  

Less action time and dependable solutions encourage and strengthen decision-making. Serviceability is a key factor when dealing with customers. Google claims its quantum computer is at least 100 times faster than existing systems.
