The Indian Union Budget 2020-21, presented on February 1, 2020, by Minister of finance Nirmala Sitharaman had a surprise for the scientific community working in the domain of Quantum computing. It was decided to make an available sum of ₹ 8,000 crores (i.e. ₹80000000000) over a period of five years (60 months) for National Mission on Quantum Technologies and Applications.
What are Quantum Technologies?
Quantum technologies are the bigger High-Tech domain which comprises the following
- Quantum Computing;
- Quantum Communication;
- Quantum Optics;
- Quantum Information Science;
- Quantum Internet and Quantum AI;
Need for special attention to Quantum Technologies
- The interest, excitement, and curiosity about quantum computers are due to their power to enable complex calculations involved in fields like real-time systems, military and space applications, and cyber-security development.
- Quantum communications can improve (cyber) security implementation, and provide unique and enhanced fingerprints for real-time systems and banking applications.
- It is believed that Quantum computing and technologies may also increase available bandwidth for internet networks (preferably Web 3.0).
What is a quantum computer?
- Quantum computers work on a series of principles and harness the varied properties of quantum physics and quantum mechanics.
- Quantum computers use logical units called quantum bits, or qubits for brief, which will be put into a quantum state where they will simultaneously represent both 0 and 1.
Difference between Traditional and quantum computers
- Since their inception, computers calculate information in binary format, called bits represented in 0 and 1.
- The binary formation in classical (traditional) computers functions distinctively from one another. On the other hand, in a Quantum computer, the qubits are interlinked, hence the status change of one qubit may affect the status of other qubits working within the system, and work in synchronization towards a common task.
How the RESULTS are achieved?
Calculations in classical computers are similar and definitive all the time, whenever we run a calculation. In Quantum computing, the calculations are probabilistic, i.e. they may produce different answers all and every time the calculations are executed.
Accordingly, to use the Quantum computing system, calculations have to run in a series of arrays or multiple times (maybe millions of times) and the array of answers or output receive, coincide or intersect towards the correct answer.
