Are Proof of Work Blockchains like Bitcoin Cryptographically Safe Against Light-Based or Quantum Hardware?

Basically, I found on another thread here that leaked research from the Skynet project that is developing some type of Light-based hardware for blockchains aside from their blockchain chips and IoT blockchain network. Didn't see very good responses about any Photonic-based cryptography so wanted to try asking again.My questions:People usually talk about Quantum Proof but the Field of Photonics seems to be possibly more advanced than quantum processors. Since Light-Based hardware is millions of times faster than conventional hardware, would Photonic ASICs be good at breaking public-key cryptography?Is Ethereum or Bitcoin resistant to Photonic Proof of Work or Quantum Proof of Work given their current consensus models?If so, what would be the ways to prevent it from happening?Paper: https://ift.tt/2N0afRs Reference: http://skynet.co/"One of the possible research areas and implementations of Skynet is a single-node photonic RC design with the Inception core. This would enable the Skynet Core to use minimal power while processing millions of times faster than conventional hardware. One of the major problems in today’s computer science is the development of new hardware that could accelerate machine learning techniques. That hardware should be inherently fast, energy-efficient, and address information exchange bottlenecks present in now ubiquitous Von Neumann architecture. We will focus specifically on the so-called single-node photonic RC, which promises additional benefit of high-speed information processing and a solution to the high-degree network connectivity problem, based on complex nonlinear delay dynamics."Although it's really tempting please don't shill projects. There's got to be a couple cryptographers in this subreddit.
