#photonicquantum — Public Fediverse posts

The quantum industry has a credibility problem, and announcements like this one from EY make it worse. EY says it installed a quantum computer in Toronto for "optimization, fraud detection, data protection and large-scale risk management." No vendor named. No qubit count. No specifications. I reached out to EY's media contact and CTO - no response.

One journalist got them to confirm it's photonic.

Here's the problem: no photonic quantum computer on Earth can do optimization, fraud detection, or risk management. Not Xanadu's. Not ORCA's. Not anyone's. The photonic modality has the largest gap to useful computation of any quantum platform I track in my CRQC Scorecard.

Buying a quantum computer before they're useful? Actually smart. I wrote many posts defending exactly that logic. Procurement cycles are long. Talent is scarce. Institutional learning takes time.

But describing a research-grade photonic prototype as a machine for "processing highly sensitive workloads" in fraud detection and risk management? That's the kind of claim that makes tech execs roll their eyes at the entire quantum industry.

Joe Depa told Accounting Today the real focus is readiness and PQC. That's honest and a praiseworthy initiative. If that's what EY said, I'd congratulate them. The press release says something else. The gap between the two is the problem.

My full analysis, including two plausible vendors, what they can actually build, and what to watch for on August 5: https://postquantum.com/industry-news/ey-quantum-computer-toronto/
