Is this the end of Bitcoin? The company announces that it is about to produce quantum desktop computers

The quantum computing, one of the main "threats" to Bitcoin, could be closer to a survey published in Physical Review X ( PRX) has unveiled a new method of access to information stored in the electrons of an atom, a fact that could be the first step in the production of quantum office. 19659003] Led by a group of scientists from the Center of Excellence for Quantum Computing and Communication Technologies (CQC2T) of the University of Sydney (Australia) and led by Professor Michelle Simmons, the researchers have developed a method to integrate one of the control gates that halve the number of gates needed, allowing qubits to be obtained with a single gate of control and a reading door.

Simmons did not provide a timetable for implementation to be widely available and when technology will begin to be "implemented" in the future. However, Wander Cunha, director of Minsait in Brazil, in an exclusive interview with Criptomoedas Fácil, revealed that companies such as D-Wave are already marketing 2,000 qubits of quantum computers acquired by companies such as Google and NASA [19659004] "The launch of the Quantum Cloud Platform is planned for 2019. This way, you will only be able to pay for the processing time without having to buy a complete computer. of this technology by more companies, "said Cunha.

Cunha is direct, "yes, it is possible for a quantum computer to destroy Bitcoin." By the very nature of the accelerated processing of the quantum computer, it can imperil not only the BTC, but all encryption system, "he said. Ulisses Mello, director of the IBM research laboratory in Brazil, also shares the view that "any transactional system using current cryptographic systems, such as blockchain or crypto-corners, could easily be broken by a quantum computer," he said. he declared.

The debate over the vulnerability of current crypto-parts to the computational power that can be implemented with quantum computing is not new. Bitcoin uses the SHA-256 hashing algorithm, RIPEMD160, and the Elliptic Curve Digital Signature of the Encryption Algorithm (ECDSA). Many believe that a quantum computer attack could compromise the ECDSA protocol, while the SHA-256 and RIPEMD160 protocols would remain immune.

On the other hand, Bitcoin and Ethereum developers point out that quantum computing poses no risk to crypto-corners and argues that Bitcoin already has integrated quantum resistance, after all, if you use them. Bitcoin addresses only once, which has always been the best practice, your ECDSA public key has only been revealed when you are spending your Bitcoins. for each address. A quantum computer would need to break its key in the short time between the moment its transaction is sent for the first time and its entry into a block, and even quantum computing is not fast enough for such a task. Currently, Bitcoin experts tend to favor a cryptographic system based on Lamport signatures. Cryptotomes such as IOTA also claim to have resistance to quantum computation.
