Quantum computing is a branch of computing that focuses on building computer technology based on quantum theory's concepts (which explains the behavior of energy and material on the atomic and subatomic levels). Computers nowadays can only encode data in bits with values of 1 or 0, severely limiting their capabilities.

Quantum computing, on the other hand, makes use of quantum bits, also known as qubits. It makes use of subatomic particles' one-of-a-kind capacity to exist in many states (i.e., a 1 and a 0 at the same time).

These supercomputers are based on the quantum physics concepts of superposition and entanglement. This enables quantum computers to perform tasks at rates that are orders of magnitude faster than traditional computers while using far less energy.

IBM, Microsoft, Google, D-Waves Systems, Alibaba, Nokia, Intel, and others have all expressed interest in working in the field of quantum computing due to its potential and predicted market size.

Quantum computers process data in a unique way. Transistors, which are either 1 or 0, are used in traditional computers. Qubits, which maybe 1 or 0 at the same moment, are used in quantum computers. Quantum computing power grows exponentially as the number of qubits connected together grows. Meanwhile, connecting additional transistors increases power in a linear fashion.

Quantum computing may be used for a variety of purposes, including securely exchanging data. Other approaches include combating cancer and other health issues, as well as creating new medicines. Quantum computers can also aid in the development of radars and their capacity to identify missiles and planes.


The current state of Quantum computing

Google is spending billions of dollars on a quantum computer that will be ready in 2029. To aid in the achievement of this aim, Google AI has built a campus in California. For years, Google has been investing in this technology. Other businesses, such as Honeywell International (HON) and International Business Machines (IBM), have followed suit (IBM). In the coming years, IBM hopes to achieve key quantum computing milestones.

While several companies have created personal (albeit pricey) quantum computers, there is yet nothing commercially accessible. Quantum computing and related technologies are also generating attention, with JPMorgan Chase and Visa investigating the concept.

Google might deploy a cloud-based quantum computing service after it has been created.

Quantum technology can also be accessed without the need to create a quantum computer. By 2023, IBM hopes to have a 1,000-qubit quantum computer operational. For the time being, IBM only grants access to its machines if they are connected to the Quantum Network. Research organizations, universities, and labs are among the members of the network.

Microsoft's Azure Quantum platform also gives businesses access to quantum technologies. Google, on the other hand, does not sell access to its quantum computers.
