Need Threads on Grapevine: Here's what I did with Quantum Computing

Created a Quantum Circuit that implements Bernstein Vazirani algorithm to find a secret binary substring faster than a classical computer. Essentially, if there is a secret substring S then it will take |S| tries for a classical computer to guess it. But using Bernstein Vazirani Algorithm does it in a single try. So, for a secret substring 1001, on a 4 qubit quantum computer, we can do a single shot computation and arrive at the string which was not seen by the circuit. Bernstein Vazirani algorithm gets the secret substring exactly as 1001 in ~636 out of every 1000 times. The erroneous values in the histogram for other possible combinations, our original secret substring was 1001, but we can also see that 0000, 0001 …. 1111 were also computed in a few cases, this error seen in the histogram is due to the quantum computing error.

Google's Willow Chip: Quantum Breakthrough

- Google unveils Willow, a 100-qubit quantum chip, achieving exponential error reduction and solving a 30-year challenge in quantum error correction. - Willow performed a standard computation in under 5 minutes, which would take a supercomputer 10 septillion years, marking a significant leap in quantum computing. - Reactions vary on Willow's impact on Bitcoin security, with experts suggesting quantum-resistant algorithms as a future safeguard.

This changes everything [HOLY F]

I've been doomscrolling through Google's latest quantum flex and I'm actually shaking rn. They just dropped the most insane quantum results since Shor decided prime numbers were cringe and developed the way to crack prime integers in polynomial time. Willow just achieved below the error correction threshold abilities. For the normies: imagine if every time you made your computer bigger it got TWICE as accurate instead of turning into a hot mess. That's literally what they did. Some highlights that are living rent-free in my head: 1. Each time they went from 3x3 -> 5x5 -> 7x7 qubits, errors dropped by 2.14x 2. Their logical qubit lives 2x longer than their best physical qubit (this is actually insane) 3. They ran 10 BILLION cycles without errors on their repetition code test The real ones know this means we're entering god-tier quantum territory. Every small improvement in the hardware gets amplified EXPONENTIALLY.
