Is a quantum computer more powerful than a supercomputer?
But what is a quantum computer? In 2019, Google’s quantum computer did a calculation in less than four minutes that would take the world’s most powerful computer 10,000 years to do. This makes Google’s quantum computer about 158 million times faster than the world’s fastest supercomputer.
How many qubits does Honeywell have?
10
Honeywell managed to achieve its real-time error correction by yoking together seven of the 10 physical qubits—the parts of a quantum computer that perform calculations—to form a single calculating unit, known as a “logical qubit.”
How many qubits does it take to build a quantum computer?
In 2015, researchers estimated that a quantum computer would need a billion qubits to do the job reliably. That’s significantly more than the 70 qubits in today’s state-of-the-art quantum computers.
Are quantum computers powerful enough to break codes?
But quantum computers change this thinking. These machines are far more powerful than classical computers and should be able to break these codes with ease. That raises an important question—when will quantum computers be powerful enough to do this?
Will quantum computers ever outperform classical ones?
In 2012, physicists used a four-qubit quantum computer to factor 143. Then in 2014 they used a similar device to factor 56,153. It’s easy to imagine that at this rate of progress, quantum computers should soon be able to outperform the best classical ones.
Are quantum computers the future of encryption?
Modern encryption methods are specifically designed so that decoding them would take so long they are practically unbreakable. But quantum computers change this thinking. These machines are far more powerful than classical computers and should be able to break these codes with ease.
