The fastest quantum chip!!

As of May 2025, the fastest quantum chip publicly known is Google's Willow processor. Revealed in December 2024, Willow is a 105-qubit superconducting quantum chip that achieved a significant milestone in quantum computing. In benchmark tests, it completed a computation in under five minutes that would take today's fastest supercomputers approximately 10 septillion years (10²⁵ years) to solve, showcasing a insane leap in speed…

So how does it work?

The Willow quantum chip by Google works using super conducting Qubits .

Wht is a qubit?

• A qubit is the basic unit of quantum information.

• Unlike a regular bit (which is 0 or 1), a qubit can be in 0, 1, or both at the same time!!! (called superposition).

• Qubits can also become entangled, which meaning their states are linked even over distance.

Now what is a super conducting qubit?

• These are super tiny loops of superconducting wire cooled near absolute zero (~15 millikelvin).

• When they are this cold they have quantum behavior and can maintain superposition and entanglement.

• The willor is Controlled using microwave pulses that flip or rotate the qubits to perform quantum logic opeations (like quantum gates).

Although there is a con with quantum computers and that is quantum error….

• A big problem in quantum computers is noise – small errors due to instability.

• Willow uses advanced error-correcting codes: instead of storing one piece of data in one qubit, it stores it across a ton , detecting and correcting errors as they occur.

• Willow demonstrated exponential error suppression, meaning that more qubits lead to less error per computation.This means we can add more qubits and also decrease the error rate.
