POPA ReconIs Bitcoin in trouble after Google's latest quantum computing breakthrough?
Is Bitcoin in trouble after Google's latest quantum computing breakthrough? Short answer: not today. But the gap is getting smaller. Google's new result makes one of the hardest parts of a quantum computer cheaper to build. That part is called "magic states." Breaking Bitcoin's math needs a very large quantum computer, and these magic states are a big part of what makes it so large. Google says the method still has to be shown at a larger scale. In March, Google estimated the attack would need fewer than 500,000 physical qubits. Earlier estimates were in the millions. A physical qubit ma…
