Google's superconducting quantum computer chip Willow has logical qubits which, for the first time in history, operate below the critical Quantum Error Correction threshold

The dawn of a new era in Cryptography.

I can smell the bs something’s raising flags …. I bet Google is highlighting one specific task where quantum speed is optimal and classical shortcuts don’t apply. Clever marketing. Also what they don’t tell you is Logical qubits! That’s the Achilles’ heel. Logical qubits rely on physical qubits, and physical qubits are fragile. If most qubits are used to stabilize the system, how many are left for actual computation? Maybe out of Willow’s 105 qubits, only a handful—let’s say 10–15 logical qubits—are doing meaningful work. They majority are mostly spinning its wheels fixing itself , its errors . Willow is inefficient, Most of Willow’s qubits are busy correcting errors, not solving problems and also a single burst of errors or environmental disturbance could collapse the computation. This thing is a proof of concept, but it’s far from being a practical quantum computer.

i'm so excited to see quantum come up and meet up with AI. that's when we'll have universe creating intelligence.

still my favorite X acct

While exciting, this is most likely a research breakthrough only. It definitely doesn't mean we have a fully functional, error-free quantum computer yet, it's a promising advancement that could accelerate quantum computing development.

Can someone please explain what he said in simpler language? 👀

Oh snap

Quantum computing stocks have started to really heat up too. Could be the next big technology boom in the public markets.
