Why is quantum computing impossible?

Why is quantum computing impossible?

Even the slightest interaction with the environment causes a qubit to collapse into a discrete state of either 0 or 1. This is called decoherence. And even before they decohere, random noise caused by non-ideal circuit elements can corrupt the state of the qubits, leading to computing errors.

Who is leading quantum computing?

At present, the unofficial record is held by USTC with 66 qubits. IBM is next with 65, followed by Google with 53 qubits, Intel (49) and Rigetti (32), according to the Quantum Computing Report. Qubit count isn’t the only factor.

Do qubits exist?

Quantum computers use quantum bits, or “qubits,” which can exist as both 1 and 0 simultaneously. This bizarre consequence of quantum mechanics is called a superposition state and is the key to the quantum computer’s advantage over classical computers. If you add more qubits, your computer’s power grows exponentially.

Do quantum computers really exist?

There are several types of quantum computers (also known as quantum computing systems), including the quantum circuit model, quantum Turing machine, adiabatic quantum computer, one-way quantum computer, and various quantum cellular automata. Quantum computers therefore require error correction.

What are the major unsolved problems in theoretical quantum mechanics?

Now that we have the theoretical basis for explaining fields, the only major unsolved problems in theoretical quantum mechanics left are: Questions of the interpretation of quantum mechanics, which are of more interest to philosophers of science than many practicing physicists.

Could quantum computers solve the problems of the future?

New paper suggests quantum computers will address problems that could have substantial scientific and economic impact. The MoFe protein, left, and the FeMoco, right, would be able to be analyzed by quantum computing to help reveal the complex chemical system behind nitrogen fixation by the enzyme nitorgense.

Why do computer problems still exist as unresolved problems?

But, these problems still exist as unresolved because scientists couldn’t prove their answers correctly, and also their answers were not accepted by the majority of other computer scientists. Computers can solve various sorts of computational problems.

Can a quantum computer be used to study chemical reactions?

Our paper published earlier this week at the Proceedings of the National Academy of Sciences confirms the feasibility of such a practical application, showing that a quantum computer can be employed to reveal reaction mechanisms in complex chemical systems, using the open problem of biological nitrogen fixation in nitrogenase as an example.
