The Quantum Security Gap

Most quantum toolchains ignore verification, reproducibility, and security. QVM fills this critical gap.

Traditional Simulators

No input validation - crash on malformed data
Random each run - impossible to reproduce
No audit trail - can't prove execution
Unlimited resources - DoS vulnerable
Run anything - no policy enforcement

QVM Approach

Mandatory verification - fail closed, always
Deterministic execution - same seed = same result
Hash-chained transcripts - cryptographic proof
Pre-flight resource checks - bounded execution
Gate whitelist & policy - explicit control

Enterprise Architecture

Defense in depth. Every layer validates. No bypass possible.

Input

QIR Bytecode / QASM / Python

Decode

Magic bytes, version, structure

Verify

Limits, whitelist, policy

Execute

Seeded PRNG, dispatch

Transcript

SHA-256 hash chain

Uncompromising Features

Every feature designed for security, reproducibility, and enterprise deployment

Mandatory Verification

Every program verified against policy before execution. Gate whitelists, qubit limits, instruction caps. No exceptions. No bypass.

Deterministic Results

Same seed = identical output. Every time. ChaCha20 seeded PRNG ensures perfect reproducibility across runs and machines.

Hash-Chained Transcripts

SHA-256 chained audit logs. Every measurement cryptographically linked. Tamper-evident. Court-admissible proof of execution.

Resource Limits

Pre-flight checks prevent runaway execution. Qubit caps, instruction limits, circuit depth bounds. DoS-resistant by design.

Multiple Backends

State-vector, Stabilizer (Clifford), and MPS tensor network simulators. Choose optimal backend for your workload.

Python & Rust APIs

Native PyO3 bindings for Python. Pure Rust core with zero external dependencies. OpenQASM 2.0 parser included.

Simple API, powerful guarantees

bell_state.py

import qvm

# Build a Bell state circuit
program = qvm.Program.builder() \
    .name("bell") \
    .qubits(2) \
    .h(0) \
    .cnot(0, 1) \
    .measure_all() \
    .build()

# Execute with deterministic seed
result = qvm.run(program, seed=42)

# Same seed = same result. ALWAYS.
result2 = qvm.run(program, seed=42)
assert result.bits == result2.bits

# Get tamper-evident transcript
print(result.transcript.final_hash())

Reproducibility You Can Prove

In quantum computing, if you can't reproduce it, you can't trust it. QVM guarantees identical results with identical seeds - a fundamental requirement for debugging, testing, and regulatory compliance.

Identical results across different machines
Cryptographic proof of execution
Policy enforcement before any execution
Zero dependencies - pure Rust core
