What are the main problems with quantum computing?

There are several challenges in building a large-scale quantum computer – fabrication, verification, and architecture. The power of quantum computing comes from the ability to store a complex state in a single bit. This also what makes quantum systems difficult to build, verify, and design.

What is the main barrier to the development of a quantum computer?

Quantum computers are exceedingly difficult to engineer, build and program. As a result, they are crippled by errors in the form of noise, faults and loss of quantum coherence, which is crucial to their operation and yet falls apart before any nontrivial program has a chance to run to completion.

What can quantum computers do better?

Google announced it has a quantum computer that is 100 million times faster than any classical computer in its lab. Rather than use more electricity, quantum computers will reduce power consumption anywhere from 100 up to 1000 times because quantum computers use quantum tunnelling. Quantum computers are very fragile.

What are the basics of quantum computing?

Quantum computing focuses on the principles of quantum theory, which deals with modern physics that explain the behavior of matter and energy of an atomic and subatomic level. Quantum computing makes use of quantum phenomena, such as quantum bits, superposition, and entanglement to perform data operations.

What companies are working on quantum computing?

1) Atom Computing. Atom Computing is a quantum computing hardware company specializing in neutral atom quantum computers. 2) Xanadu. Xanadu is a Canadian quantum technology company with the mission to build quantum computers that are useful and available to people everywhere. 3) IBM. 4) ColdQuanta. 5) Zapata Computing. 6) Azure Quantum. 7) D-Wave. 8) Strangeworks.

What is D Wave computer?

D-Wave is a company that specializes in Quantum Computing and Quantum Information. Their biggest product is, of course, the quantum computer.

What is IBM Q?

The IBM Q Experience is an online platform that gives users in the general public access to a set of IBM’s prototype quantum processors via the Cloud, an online internet forum for discussing quantum computing relevant topics, a set of tutorials on how to program the IBM Q devices, and other educational material about quantum computing.
