What is Sycamor Computer?

Google's new quantum computer is called the Sycamore 2.0, and it was announced in July 2023. It has 70 operational qubits, which is a significant increase from the 53 qubits of the original Sycamore processor. This makes the Sycamore 2.0 approximately 241 million times more powerful than its predecessor.

The Sycamore 2.0 is still a prototype, but it is a significant step forward in the development of quantum computers. It is the first quantum computer to achieve quantum supremacy, which means that it can perform a calculation that would be impractical with a classical computer.

The Sycamore 2.0 is still not powerful enough for practical applications, but it is a major milestone in the development of quantum computing. As quantum computers continue to improve, they have the potential to revolutionize many different fields, including cryptography, drug discovery, and artificial intelligence.

 What is different in between Classical computers and Quantum computer?

The main difference between classical computers and quantum computers is how they store and process information. Classical computers use bits, which can be either 0 or 1. Quantum computers use qubits, which can be both 0 and 1 at the same time. This property of qubits, known as superposition, allows quantum computers to perform calculations that are impossible for classical computers.

Another difference between classical computers and quantum computers is the way they operate. Classical computers operate in a linear fashion, meaning that they perform one operation at a time. Quantum computers operate in a non-linear fashion, meaning that they can perform multiple operations at the same time. This property of quantum computers, known as entanglement, allows them to solve problems that would be intractable for classical computers.

 

A quantum computer could factor a 2,048-bit number in a few minutes, while a classical computer would take billions of years to do the same calculation. This is because quantum computers can take advantage of the properties of superposition and entanglement to perform calculations that would be impossible for classical computers.

As quantum computers continue to develop, their speed advantage is expected to grow. Eventually, quantum computers may be able to solve problems that are completely intractable for classical computers.
