How to Break RSA 2048

If you want to break RSA 2048, which is our current encryption standard, you would need about 4,000 perfect, theoretically perfect qubits. With the currently available hardware that is still in this so-called noisy intermediate scale quantum era, you need to use a lot of these currently available physical qubits to build one of these perfect logical qubits. To break RSA 2048,. you would need at least four to 10 million qubits if you see where I'm going with it. Right now, we have a handful. The other challenge is or the other advantage is we have already post-quantum crypto schemes in place. So we have new ways of protecting the data using classical technologies.
