The Problem
Today’s Encryption Methods Won’t Survive Quantum Threats.
Quantum computers have the potential to break classical encryption such as RSA and ECC, exposing today's sensitive communications. Post-quantum algorithms (PQC) can only provide temporary safety, leaving critical data vulnerable as quantum technology advances.
Organizations urgently require a future-proof solution without extensive new infrastructure. zerothird’s Key-as-a-Service addresses this need directly by delivering quantum keys derived from entangled photons. When supported, these keys can be integrated into existing encryption devices and key management systems—avoiding the need for new hardware or operational complexity.

Key Benefit
Quantum-Generated Keys—Security Simplified, Zero CAPEX.
With KaaS, your organization gets quantum-safe encryption. Keys are derived from entangled photons distributed from a secure source, removing infrastructure burden and accelerating quantum readiness.
The Details
zerothird Hardware.
zerothird builds and operates the physical quantum infrastructure required for key delivery—supporting both direct-link and trusted-node deployments.
In both models, keys remain isolated from zerothird personnel and never leave the client’s secure environment. When supported, we integrate directly into your encryption systems, minimizing disruption while mitigating the need for in-house hardware expertise.
Frequently Asked Questions
How exactly does Key-as-a-Service KaaS work?
zerothird generates quantum keys using entangled photons via hardware fully owned and operated by zerothird. These keys are temporarily and securely stored in a local key vault—never forwarded to any zerothird facility or software–until retrieved by the client. Clients retrieve keys directly via standardized interfaces for real-time encryption within their own systems.
In long-distance links requiring trusted nodes, quantum keys are generated and temporarily stored at intermediate points fully owned and operated by zerothird. These trusted nodes are maintained under strict physical, IT, and operational security. Once relayed, the keys are made accessible to the client’s endpoints, where they’re pulled and used locally, without zerothird ever accessing their content. Across both models, zerothird maintains operational responsibility while ensuring clients retain control over when and how keys are applied. The KaaS model also shifts cost from CapEx to OpEx, ultimately reducing procurement delays and accelerating implementation timelines through simplified budgeting.
Does KaaS require us to replace our encryption systems?
When supported, KaaS integrates seamlessly into your current cryptographic environment. We provide quantum-safe keys directly to your endpoints, allowing existing encryption hardware and software to remain in use, significantly reducing integration complexity and cost.
What differentiates zerothird’s KaaS from standard QKD systems?
Traditional QKD systems require customers to purchase, install, and operate dedicated hardware. With KaaS, zerothird owns and operates the entangled photon source, which is typically deployed within or near the customer’s infrastructure, and delivers quantum-safe keys directly into existing encryption systems. This may reduce deployment time, operational overhead, and capital expenses while ensuring uncompromised quantum security.
Is KaaS secure enough for regulated industries?
While formal quantum cryptography standards are still evolving, KaaS is designed to meet the security expectations of highly regulated industries. Our keys are derived from entangled photons, providing information-theoretic security that aligns with the highest levels of cryptographic assurance.
How does zerothird ensure reliable key delivery under network disruptions or attacks?
Unlike live session key exchange systems, zerothird’s architecture uses buffered quantum keys, making the service resistant to denial-of-service attacks and resilient during temporary outages. This buffering allows key distribution to continue even if one side experiences maintenance or limited downtime, supporting continuous secure communication.
What does the KaaS deployment process look like?
KaaS deployments are designed to minimize operational burden for your team. While lead times vary depending on system availability and site preparation, ZeroThird handles the complexity of hardware delivery, installation, and key delivery integration—streamlining your path to quantum-secure communications.
How are encryption keys handled before I use them?
The keys are temporarily and securely stored in a local key vault—never forwarded or downloaded to any zerothird facility or software—until retrieved by the client.
