Future of Quantum Computing in 2021: in-Depth Guide
November 20, by Robin Mitchell With advances in quantum computers becoming the norm and practical machines soon becoming a reality, the world faces a serious security threat. How will Bitcoin, a digital-based cryptocurrency, survive against such a threat and what will this mean for the value of Bitcoin? Will quantum computing undermine the security of cryptocurrencies like Bitcoin?
A Quantifiable Risk Quantum computers, for all of their press, will not be used in everyday applications such as running word processors or playing games. D-Wave quantum computer.

Cryptocurrencies enable near full autonomy , allowing individuals and businesses alike to purchase goods and services without revealing their identities as individuals have addresses which are not associated with names or information regarding the owner.
The system relies on encryption to keep wallets which essentially store user Bitcoins secure so that others cannot access the Bitcoins. Bitcoin is decentralized which means that there is no Bank of Bitcoin or a single server that is responsible for the entire system this could lead to abuse.

The Bitcoin system is maintained and supported by all computers on the network with all transactions being recorded in a public ledger. Bitcoin, the most famous cryptocurrency is heavily dependent on encryption.

Bruteforcing usually doesn't refer to a password prompt, it refers to cracking encrypted data files or password hashes that have been acquired.
Jonathan Cressman December 02, Robin Mitchell should read the bitcoin spec. Different approaches for different applications seem to be the most likely solution now. Currently, some approaches explored by QC companies are analog quantum model, universal quantum gate model and quantum annealing. Manufacturing stable quantum processors and error correction: In order to take advantage of the properties of quantum mechanics, it is needed to perform manipulations at smaller scales, sometimes smaller than an atom.

Small scales cause stability and error verification problems. Quantum researchers state that error-correction in qubits is more valuable than the total number of qubits obtained. Since qubits cannot be controlled with accuracy, it remains a challenge to solve complex problems. Maintaining the extreme operating conditions : In order to increase stability and control qubits, IBM keeps temperature so cold 15 milliKelvin that there is no ambient noise or heat to excite the superconducting qubit. Keeping the temperature so low also creates stability problems in itself.
For broad commercialization of a quantum computer or processor, operating conditions should be improved.
Your Answer
Quantum researchers are looking for ways to use quantum processors at higher temperatures. The highest operating temperature has been reached recently. However, it seems to take more time to operate these systems at room temperature. Problems such as stability and error correction are dependent on technology investment, research resources and developments in quantum mechanics.
Different organizations are trying to obtain the most accessible quantum computer technology by trying different methods. It will take a while to see which approach will bring success in different areas. Your feedback is valuable. We will do our best to improve our work based on it.
