This has not led to good outcomes, my vision is starting to decline; I will soon have to turn to Meklon. I think it's time to systematically summarize the main parameters of a quantum computer. There are several: Number of qubits, Coherence time (decoherence time), Error rate, Processor architecture […]

Additional functionality (for example, the ability to switch to stronger settings without knowing the password) out of the box. Utilization of cryptographic primitives approved by NIST. The possibility remains [...]
