&gt; The first group to get a working qbit based computer will be able to break all current encryption.<p>All you have to do is increase the key-size faster than quantum can break it.  Also there are many new algorithms being studied that quantum doesn&#x27;t work on.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Post-quantum_cryptography" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Post-quantum_cryptography</a>
