Computer science’s application of quantum theory is known as quantum computing. Quantum theory explains the behavior of energy and matter at the atomic and subatomic scales.
Quantum computing consists of subatomic particles like electrons or photons. These particles can exist simultaneously in two states (i.e., 1 and 0) or qubits.
Linked qubits theoretically can “exploit the interference between their wave-like quantum states to perform calculations that might otherwise take millions of years.”
Traditional computers nowadays use a binary stream of electrical impulses (1 and 0). Compared to quantum computing, this limits their ability to process information.
- Quantum computing uses quantum physics phenomena.
- Quantum computing uses qubits.
- A qubit can exist in a multidimensional state compared to a standard computer bit, which can only be 0 or 1.
- With additional qubits, quantum computers’ power increases exponentially.
- The power of traditional computers can only grow linearly with more bits.
Knowledge of Quantum Computing
The 1980s saw the emergence of the quantum computing field. Some issues could be solved more effectively by quantum algorithms than classical ones.
Quantum computing can sort through enormous quantities of options and identify potential answers to issues. Quantum computers use qubits that can store a high amount of information. Qubits store data in a multidimensional quantum state.
Some of the biggest companies have taken notice of this enormous processing capacity and the anticipated size of the market for its utilization. These include NEC, Raytheon, Lockheed Martin, Rigetti, IBM, Microsoft, Google, D-Waves Systems, Alibaba, Nokia, Intel, Airbus, HP, Toshiba, Mitsubishi, SK Telecom, Biogen, Volkswagen, and Amgen.
Application and Advantages of Quantum Computing
The domains of security, finance, military affairs and intelligence, drug development, aircraft design, utilities (nuclear fusion), polymer design, machine learning, artificial intelligence (AI), data search, and digital manufacturing could all benefit substantially from quantum computing.
Information sharing could be made more secure with the help of quantum computers. Quantum computing can also increase the capability of the radar. The environment and maintaining clean water with chemical sensors is another area where quantum computing can be helpful.
Advantages of Quantum Computing:
- Quantum computing may allow financial institutions to create investment portfolios for individual and institutional clients that are more effective and efficient. They may concentrate on enhancing fraud detection and developing better trading simulators.
- Quantum computing can help the healthcare sector to create novel medications and genetically focused treatments. It might also fuel more sophisticated DNA studies.
- Quantum computing can help to create more secure data encryption and methods for detecting system intrusions using light signals.
- Systems for planning traffic and designing more effective, safe aircraft can benefit from quantum computing.
