That would be fun to watch, but to be overly pedantic about it, it will take a computer with hundreds of qubits to break current public key encryption.
It will take hundreds of fault tolerant qubits. That means it will take potentially millions of physical qubits of relatively high quality. There is a long road ahead from 72 relatively medium quality to millions of relatively high quality qubits.
As a layman, I've never heard of qubit quality. What is it exactly? How do you determine it? And why does it affect computation?
Qubit quality is defined by the quantum volume [0]. Errors that occur when gates are applied to qubits need to be below a certain threshold to perform error correction.
