I first learned about SPAC via Barron's and discovered it was seriously undervalued. Although it is a company that promotes quantum computing and quantum encryption, what it does is not as complicated as domestic quantum technology, so it is not a big technical problem. Normal encryption requires a public key, a string of numbers that is generated in advance by some random algorithm and distributed when needed. What Arqit does is: 1） Generate when you want to use it, so as to prevent others from intercepting it at other times, which is a speed problem; 2） with quantum equipment generation guarantee completely random. Compared with quantum computing, it has no hard technology challenges on hardware devices, and compared with Quantumctek, it has no single-photon transmission challenges of satellite or optical fiber over long distances. To put it plainly, it is completely random number plus a time difference of speed. Theoretically, it cannot completely eliminate the threat of quantum computing or other attacks, but it does reduce the risk factor greatly if the calculation is fast enough. $Arqit Quantum (ARQQ.US)$
