01
Simulator-First

Research & Develop Now

  • Prototype complex circuits on Blackwell clusters noise-free, today
  • CUDA-Q code runs natively on future QPUs: ion-trap, superconducting, or photonic
  • Simulations serve as ground truth to validate noisy physical quantum results

Predictable OpEx

Cost Optimization & Viability

  • FP4/FP6/FP8 precision enables massive state-vector compression on Blackwell
  • MPI parallelization lowers cost-per-experiment vs. sequential QPU access
  • Blackwell clusters dual-use: Quantum Simulation by day, AI/LLM training by night
03
Frictionless Hybrid

The Classical-Quantum Bridge

  • NVLink provides high-bandwidth Grace CPU to Blackwell GPU coherence
  • On-fabric VQE/QAOA loops converge faster, eliminating network bottlenecks
  • Hybrid CUDA-Q workflows deliver XAI transparency for regulatory compliance
02   Executive Perspective

"The competitive advantage is not in owning a quantum computer. It is in building the algorithms, workflows, and institutional knowledge before your competitors can access the hardware."

04   Simulation Modalities & Fidelity
Highest Fidelity

State Vector Simulation

The gold standard. Tracks every quantum amplitude exactly — no approximations, no noise assumptions. Computationally intensive by design; memory scales exponentially with qubit count. The only method that delivers complete, mathematically exact circuit results.

GPUs (B300) Total VRAM Max Qubits Use Case
1 GPU 288 GB ~34 Qubits Small molecule ground-state (VQE)
100 GPUs 28.8 TB ~40 Qubits Complex chemical catalysts
1,000 GPUs 288 TB ~44 Qubits Large-scale materials science
5,000 GPUs 1.44 PB ~46 Qubits Pushing the "Quantum Supremacy" boundary
Scalable Fidelity

Tensor Network Simulation

The engineering compromise that unlocks scale. By representing quantum states as contracted tensor graphs, memory requirements grow polynomially — not exponentially. Ideal for circuits with limited entanglement, enabling simulation of thousands of qubits. The method of choice for large-scale optimization and QML workloads.

GPUs (B300) Max Qubits Enterprise Use Case
100 GPUs ~1,000 Qubits Optimization (QAOA) for logistics
1,000 GPUs ~5,000 Qubits Quantum ML (QML) kernels
5,000 GPUs >10,000 Qubits Digital Twin of QPU topologies
Massive Scale · Clifford-Only

Stabilizer Circuit Simulation

The specialist for fault-tolerant quantum computing research. Restricted to Clifford-group operations, but exploits this to simulate millions of qubits efficiently — something no other method approaches. The essential tool for validating quantum error correction codes and Post-Quantum Cryptography at infrastructure scale.

GPUs (B300) Max Qubits Enterprise Use Case
100 GPUs ~1,000,000 Qubits Surface Code error correction testing
1,000+ GPUs Multi-Million Qubits Simulating full fault-tolerant quantum computers
05   Industry Applications
Pharmaceuticals

Molecular Discovery

Simulating electronic structure of metalloenzymes and protein-ligand interactions at chemical accuracy — beyond classical HPC limits, without relying on noisy QPUs.

Molecules too large for classical simulation. Too sensitive for noisy quantum. Exactly the gap Blackwell fills.

Defense

Sovereign Security

Large-scale simulation of Stabilizer Circuits and Post-Quantum Cryptography (PQC) hardening — fully air-gapped, on-premise Blackwell deployments for national infrastructure.

Complete data sovereignty. No cloud dependency. Cryptographic resilience before the threat arrives.

Big Tech

Optimization & AI

Auto-Kernel Discovery for high-dimensional image classification and supply chain logistics via CUAOA — leveraging quantum feature spaces to surface non-obvious dataset correlations.

Classical ML has plateaued. Quantum feature spaces reveal what gradient descent cannot.

06   Academic Validation
cuQuantum Foundation

The cuQuantum SDK introduces high-performance libraries — cuStateVec and cuTensorNet — capable of scaling simulation to 5,000 qubits on commodity GPU clusters.

Hybrid ML & XAI

Recent studies leverage CUDA-Q for hybrid Quantum Neural Networks with Explainable AI focus — a critical compliance requirement for regulated industries.

CUAOA Optimization

The CUAOA framework provides a novel CUDA-accelerated QAOA implementation that outperforms all standard classical simulation tools in benchmark testing.

Circuit Partitioning

Analysis of circuit partitioning versus full-circuit execution highlights the necessity of multi-node MPI configurations for enterprise-scale quantum workloads.

QuaSARQ Scaling

The QuaSARQ framework has achieved simulation of 180,000 qubits, delivering a 105× speedup over Stim — the previous industry benchmark for stabilizer simulation.

Performance Benchmarks

Qiskit Aer with cuQuantum on NVIDIA GPUs has demonstrated 14× baseline speedup, with select backends reaching 146× over NumPy-based implementations.

build before the race
