⚠ Migrate Now
Classical Assumption
RSA / ECC — Security Through Hard Maths
X.509 certificates, TLS handshakes, and mTLS between services all rely on integer factorisation and discrete logarithm problems that classical computers cannot solve in feasible time. Your Vault PKI, cert-manager issuers, and Istio mTLS chains depend entirely on this assumption holding — indefinitely, for the full lifetime of every secret you encrypt today.
Quantum Reality
Shor's Algorithm + Harvest Now, Decrypt Later
A sufficiently large quantum computer solves RSA and ECC in polynomial time using Shor's algorithm. The "harvest now, decrypt later" threat is active today — adversaries record your encrypted traffic now to decrypt it when hardware matures. The Global Risk Institute estimates an 11–31% probability RSA is broken by 2030. For pharmaceutical clients, regulatory data lifetime extends that exposure window significantly.

etcd — Control Plane Store
Source of Truth · k8s v1.33+ PQC architectural gap · Go version skew risk
⚠ Known Gap
Classical Assumption
Persistent, Copyable, Snapshotable State
etcd assumes all cluster state survives indefinitely, is readable on demand, and can be snapshotted, backed up, and restored at will. Every Kubernetes control loop — from the scheduler to kubelet reconciliation — depends entirely on these classical storage guarantees. The core assumption: you can read state without affecting it. This has never been questioned because it has always been physically true.
Quantum Reality
The PQC Gap Nobody Is Writing About
Kubernetes 1.33+ ships hybrid PQC (X25519MLKEM768) on the API server, kubelet, scheduler, and controller-manager via Go 1.24. But etcd deliberately runs an older Go version for stability. Your most critical data store — every secret, configmap, and pod spec — remains classically encrypted. This is an architectural gap, not a configuration error.
⚠ Run: etcd --version | grep -i go — if Go < 1.24, your secrets store is classically encrypted regardless of what PQC your API server is doing. These are two independently encrypted channels.

✓ Partially Fixed
Classical Assumption
Classical Key Exchange — X25519 / ECDHE
All control plane communication — kubectl, kubelets, controllers — has historically been secured by elliptic curve key exchange alone. Every cluster running Go <1.24 remains fully in this mode. Managed clusters (AKS, EKS, GKE) manage their own Go toolchain and upgrade cadences independently of upstream Kubernetes — you cannot assume PQC just because your k8s version is current.
Quantum Reality
Hybrid PQC Lands in v1.33+ — Watch for Silent Downgrade
Kubernetes 1.33+ on Go 1.24 enables X25519MLKEM768 hybrid key exchange by default on the API server. OpenShift 4.20 applies it across the full control plane. Critical caveat: if your cluster runs Go 1.23 but you access it with kubectl built on Go 1.24, the connection silently downgrades to classical X25519 — no error, no warning, no log entry. Your PQC protection disappears during version skew windows.
✓ Verify now: kubectl version -o json | jq '.serverVersion.goVersion' — must show go1.24+ on both client and server. Managed clusters vary — check before assuming PQC is active on your AKS/EKS/GKE control plane.

Container Runtime
containerd · runc · CRI · Pod lifecycle · Liveness/Readiness probes · Checkpointing
~ Model Breaks
Classical Assumption
Persistent, Restartable, Deterministic Process
A running container holds state in memory, can be paused and checkpointed, responds to health probes with deterministic healthy/unhealthy answers, and has reproducible restart behaviour. The pod lifecycle model assumes classical OS process semantics at every layer — start, run, observe, probe, terminate. Running the same container twice produces the same observable output under the same input conditions.
Quantum Reality
State Collapses on Measurement — Pod Model Fundamentally Breaks
A quantum circuit cannot be paused, checkpointed, or restarted — measuring it collapses its superposition. Liveness probes have no quantum equivalent: the same circuit run twice returns different results by design. The Qubernetes project (arXiv:2408.01436, Osaka/Fujitsu, Jul 2024) maps quantum circuits to Kubernetes CRDs as a parallel model — not an extension of pods. Key research finding: "a quantum service cannot be deployed permanently — the circuit must be compiled and sent to the quantum device fresh at runtime."

Scheduler / HPA
kube-scheduler · HPA · VPA · KEDA · Bin-packing · Replica scaling
~ Two Breaks
Classical Assumption
CPU / Memory Bin-Packing + Infinite Pod Lifetime
kube-scheduler assigns pods based on resource requests, limits, affinity, and taints — optimising against a resource budget. HPA scales by replicating identical stateless instances horizontally. The no-cloning assumption is implicit throughout this model: of course you can copy a container image and start another replica. Time is unlimited — a pod runs until you decide to terminate it.
Quantum Reality
Coherence Windows + No-Cloning: Two Completely Independent Breaks
Quantum circuits must complete within microsecond-to-millisecond decoherence windows — the scheduler races against physics, not a CPU quota. Separately, HPA is fundamentally broken for quantum state: the no-cloning theorem prohibits copying arbitrary quantum state, so spinning up another "replica" is physically impossible. IBM Kookaburra (2026, 1,386 qubits) will begin testing hybrid scheduling at commercial scale.

Observability
Prometheus · Grafana · Loki · OpenTelemetry · Jaeger · CNCF observability stack
~ Research Horizon
Classical Assumption
Passive, Non-Destructive, Continuous Instrumentation
Every operation emits a log line, metric increment, or trace span. Observing the system at any point does not affect its state. Prometheus can scrape a target indefinitely — nothing changes in the workload because you looked at it. This foundational assumption underlies every single tool in the CNCF observability landscape. It has never had to be questioned because it has always been physically true.
Quantum Reality
Measurement Destroys State — No Prometheus Equivalent Exists
Observing a quantum system collapses its superposition — the act of measurement changes the result. Classical observability is fundamentally passive; quantum observability is fundamentally interventional. Quantum workloads require entirely new primitives: fidelity metrics, shot-count statistical sampling, decoherence rate tracking, and per-gate error rates. As of 2026 this remains an open research problem — no production quantum observability toolchain exists anywhere. The QCaaS market growing at 34–43% CAGR means it will eventually need to be solved commercially.
