Google Willow Quantum Processor Now Open to Researchers — How to Apply for Access

Google has opened the Google Willow quantum processor to external researchers through Google Cloud Quantum AI, marking the first time commercial access to a state-of-the-art quantum system with 105 qubits and real-time error correction is available outside of Google’s own research teams.

What Is Google Willow?

Willow is Google’s most advanced quantum processor, announced in late 2024 and now available to researchers. Its key achievement is exponential error reduction as qubit count increases — a fundamental breakthrough that makes practical quantum computing more achievable.

Technical Specifications

• Qubits: 105 physical qubits
• Error rate: Sub-threshold error correction demonstrated
• Benchmark: Solved RCS problem in 5 minutes (would take 10 septillion years classically)
• Connectivity: 2D grid topology with nearest-neighbor connectivity
• Gate fidelity: 99.85% two-qubit gate fidelity

How to Apply for Access

Google offers research access through two programs:

• Google Quantum AI Research Program: For academic institutions and national labs — applications at quantumai.google/research
• Google Cloud Quantum Computing Service: Commercial API access via Google Cloud (waitlist)

Getting Started with Quantum Programming

# Install Cirq (Google's quantum programming framework)
pip install cirq

# Create a simple quantum circuit
import cirq

# Create qubits
q0, q1 = cirq.LineQubit.range(2)

# Create Bell state (quantum entanglement)
circuit = cirq.Circuit([
    cirq.H(q0),           # Hadamard gate — creates superposition
    cirq.CNOT(q0, q1),    # Entangle q0 and q1
    cirq.measure(q0, q1, key='result')
])

print(circuit)

# Simulate locally
simulator = cirq.Simulator()
result = simulator.run(circuit, repetitions=1000)
print(result.histogram(key='result'))

# Submit to real Willow hardware (requires access)
# from cirq_google import Engine
# engine = Engine(project_id='your-project')
# result = engine.run(circuit, processor_id='willow', repetitions=1000)

Implications for Cybersecurity

Willow’s advancement brings the threat to classical encryption closer to reality:

• RSA-2048 could theoretically be broken with ~4,000 error-corrected logical qubits
• Willow has 105 physical qubits — still far from the millions needed for cryptographic attacks
• NIST post-quantum cryptography standards (ML-KEM, ML-DSA) are now finalized
• Organizations should begin migrating to post-quantum algorithms now

Migrating to Post-Quantum Cryptography

# Install OpenSSL with PQC support
sudo apt install openssl libssl-dev

# Generate ML-KEM (formerly CRYSTALS-Kyber) keypair
openssl genpkey -algorithm ML-KEM-768 -out pq-private.pem
openssl pkey -in pq-private.pem -pubout -out pq-public.pem

# Python with PQC library
pip install pqcrypto
from pqcrypto.kem.kyber768 import generate_keypair, encrypt, decrypt
public_key, secret_key = generate_keypair()

The SudoFlare Takeaway

Willow is impressive but not yet a threat to encryption — we are still 10-15 years from cryptographically relevant quantum computers. However, “harvest now, decrypt later” attacks are real: adversaries are collecting encrypted traffic today to decrypt once quantum computers mature. Start planning your post-quantum migration now, especially for data with a long secrecy lifetime.
