Quantum Doom for Crypto? It’s all FUD and here’s why

From Steemit, Rafael Duval (@cryptoeagle), shares his quantum vision with his last original article:

Today I want to share with you a very interesting article that I found while reading about cryptography and its supposed archenemy, Quantum Computing.

How many times have we seen fear, uncertainty, and doubt (FUD) spread on social networks about how quantum computing would break Bitcoin encryption and turn it, and most cryptographic currencies, into obsolete ones? With a market price of 400 billion dollars, the greatest reward of a hacker ever, why did not it happen? Could you ask?

Well, here’s the answer: there are physical limitations that make quantum supremacy, the point at which quantum computers beat classic computers, impossible to achieve. It’s about noise, a fundamental barrier that can not be broken no matter how much money is stolen by IBM, Google or Amazon to make super expensive chandeliers.

They are all FUD types, fake news designed to make you sell your coins at a low price. Make HODL and get your candlesticks in a thrift store for $ 5;)

The mathematician Gil Kalai believes that quantum computers can not work, even in principle

Hace 16 años, en un frío día de febrero en la Universidad de Yale, un póster llamó la atención de Gil Kalai. Publicó una serie de conferencias de Michel Devoret , un conocido experto en esfuerzos experimentales en computación cuántica. Las conversaciones prometieron explorar la pregunta “Computadora cuántica: ¿milagro o espejismo?” Kalai esperaba una discusión vigorosa de los pros y los contras de la computación cuántica. En cambio, recordó, “la dirección escéptica fue un poco descuidada”. Se propuso explorar ese punto de vista escéptico.

Hoy, Kalai , un matemático de la Universidad Hebrea de Jerusalén, es uno de los más prominentes de un grupo de matemáticos, físicos e informáticos que argumentan que la computación cuántica, a pesar de su promesa teórica, es algo así como un espejismo. Algunos argumentan que existen buenas razones teóricas por las que las entrañas de una computadora cuántica, los “qubits”, nunca podrán realizar consistentemente la compleja coreografía que se les pide. Otros dicen que las máquinas nunca funcionarán en la práctica, o que si se construyen, sus ventajas no serán suficientes para compensar el gasto.

Sixteen years ago, on a cold February day at Yale University, a poster caught Gil Kalai’s attention. He published a series of lectures by Michel Devoret, a well-known expert in experimental efforts in quantum computing. The talks promised to explore the question “Quantum computer: miracle or mirage?” Kalai expected a vigorous discussion of the pros and cons of quantum computing. Instead, he recalled, “the skeptical leadership was a bit neglected.” He set out to explore that skeptical point of view.

Today, Kalai, a mathematician at the Hebrew University of Jerusalem, is one of the most prominent of a group of mathematicians, physicists and computer scientists who argue that quantum computing, despite its theoretical promise, is something of a mirage. Some argue that there are good theoretical reasons why the entrails of a quantum computer, the “qubits”, can never consistently perform the complex choreography that is asked of them. Others say that machines will never work in practice, or that if they are built, their advantages will not be enough to offset the expense.

Even if Quantum Computing’s noise problem could ever be resolved. Bitcoin could just upgrade its encryption and make it Quantum proof. Here’s Andreas Antonopoulos to explain this:
