The statement is not true.
Most remote access VPNs use SSL/TLS to secure the traffic end to end. Traffic within that tunnel is fully encrypted. While a capture of the full session might conceivably be played back in n years once quantum computing advancements allows for cracking of that encrypted session, it is likely going to be some years before that is possible and then only to large state-sponsored actors (think the US National Security Agency, People's Republic of China etc.). So it's not likely that your traffic in transit - whether it be from your home office or the local coffee shop - will be subject to that anytime soon.
Meanwhile, VPN vendors (Cisco included) are starting to introduce support for quantum-resistant encryption algorithms. By the time quantum computing is generally available, your VPN will likely be using post-quantum computing (PQC) type algorithms.
Note that IPsec (the method used for most site-to-site and some remote access VPNs) uses symmetric key encryption and is not vulnerable to quantum computing-based decryption methods.
Bottom line: quotations like the one you mention are mostly click bait designed to get the reader to open an article loaded with ads.
