# Google Launches Gemini Notebook to Help Organizations Prepare for Post-Quantum Cryptography

> Google Cloud has launched a public Gemini Notebook that helps CISOs, policymakers, and developers understand post-quantum cryptography, explore Google's research, and prepare for the transition to quantum-resistant security.

Source: **Google Cloud Blog** · 15 October 2026

**G**oogle Cloud has introduced a public Gemini Notebook designed to help chief information security officers (CISOs), policymakers, developers, and other security professionals understand post-quantum cryptography (PQC) and prepare for its adoption. The resource brings Google's research, engineering blogs, and migration guidance together in an interactive learning environment.

The announcement comes as Google highlights the potential long-term risks that quantum computing could pose to widely used public-key encryption. The company warns that attackers could collect encrypted information today and attempt to decrypt it in the future when sufficiently powerful quantum computers become available.

The notebook offers source-grounded answers, audio overviews, flashcards, visual explanations, and briefing documents to help users learn about the quantum threat and plan their organization's cryptographic migration.

## 
Why Post-Quantum Cryptography Matters Now

Post-quantum cryptography refers to cryptographic algorithms designed to resist attacks from both classical computers and future quantum computers. It is intended to protect digital systems against quantum computing capabilities that could undermine some of today's widely used public-key cryptographic schemes.

Google's research estimates that breaking elliptic-curve discrete logarithm cryptography using a 256-bit key, known as [ECDLP-256](https://arxiv.org/abs/2603.28846), could require approximately 500,000 imperfect quantum computer components, or noisy qubits. Breaking [RSA-2048](https://arxiv.org/abs/2505.15917) encryption could require approximately one million noisy qubits, according to the company's estimates.

These figures are research estimates, not evidence that a quantum computer capable of breaking these schemes is currently available.

Google points to advances in its [Willow quantum chip](https://blog.google/innovation-and-ai/technology/research/google-willow-quantum-chip/) and [Quantum Echoes algorithm](https://blog.google/innovation-and-ai/technology/research/quantum-echoes-willow-verifiable-quantum-advantage/) as examples of progress in quantum computing research. It argues that organizations should not wait for a cryptographically relevant quantum computer to become available before preparing their security systems.

### 
The Risk of Store-Now, Decrypt-Later Attacks

One concern is the [store-now, decrypt-later](https://www.ietf.org/archive/id/draft-reddy-uta-pqc-app-03.html#name-timeline-for-transition) attack model. In this scenario, an attacker collects encrypted information today and stores it in the hope of decrypting it when future quantum capabilities make that possible.

This creates a long-term risk for information that must remain confidential for years, including health records, financial information, intellectual property, and government data.

Organizations may therefore need to evaluate not only whether their current encryption is secure today, but also how long their sensitive information must remain protected.

## Google's Gemini Notebook Brings PQC Research Together

Google's new public resource, [**Prepare for Post-Quantum Cryptography**](https://notebook.google.com/notebook/68849586-67c5-4165-8f72-64a61991f1dd?original_referer=https:%2F%2Fcloud.google.com%23&pli=1), is designed to make technical research more accessible to security leaders and other audiences who need to understand the issue but may not specialize in cryptography.

The notebook draws on a curated collection of Google sources covering quantum computing, research breakthroughs, industry PQC standards, Google's deployments, and migration guidance.

Users can interact with the material through several learning features:

- **Source-grounded answers:** Ask questions and receive responses based on the notebook's curated Google sources.
- **Audio overview:** Listen to a podcast-style summary of the material.
- **Flashcards:** Test understanding of PQC concepts and terminology.
- **Interactive visual diagram:** Explore a visual explanation of the quantum threat.
- **Briefing document:** Read a concise overview of the subject.

The company also provides suggested prompts for different audiences. CISOs can ask what to prioritize during the first 90 days of a PQC migration. Beginners can explore the meaning of store-now, decrypt-later attacks, while developers can ask how hybrid ML-KEM key exchange works in Chrome.

Google cautions that, like other generative AI systems, the notebook can make mistakes. Users should verify its answers against the linked source material rather than treating generated responses as authoritative security guidance.

## 
What CISOs Should Prioritize Before PQC Migration

Google recommends that security leaders begin by identifying where vulnerable cryptography exists across their organizations. This includes understanding which systems depend on cryptographic mechanisms that may need to change as PQC adoption progresses.

The company outlines several priorities for CISOs.

### 
1. Build a Cryptographic Inventory

Organizations need to understand where cryptography is used across their systems, applications, infrastructure, and data flows. Without this visibility, security teams may struggle to identify the systems that require attention or estimate the scope of a migration.

### 
2. Prioritize Sensitive Data and Critical Systems

Security teams should identify information and systems that face the greatest risk from future quantum capabilities. Data that must remain confidential for an extended period deserves particular consideration when evaluating store-now, decrypt-later exposure.

### 
3. Assess System-Wide Dependencies

Cryptographic changes can affect connected systems, applications, and operational processes. Google advises organizations to anticipate the broader consequences of PQC migration instead of treating it as an isolated algorithm replacement.

### 
4. Develop Crypto-Agility

Crypto-agility is the ability to update or replace cryptographic algorithms and mechanisms without requiring extensive redesign of an entire system. Google recommends incorporating this capability into security planning and drawing lessons from previous cryptographic transitions and incidents, including Heartbleed.

## Google's PQC Migration Timeline and Policy Recommendations

Google has published a [migration timeline](https://blog.google/innovation-and-ai/technology/safety-security/cryptography-migration-timeline/) outlining its plans to transition to post-quantum cryptography by 2029. The company urges other organizations to consider similar preparation, although the appropriate timeline will depend on their own systems, dependencies, and requirements.

Google also calls on policymakers to consider the implications for critical infrastructure. Its recommendations include recognizing potentially condensed migration timelines, incorporating PQC readiness into existing risk-management plans, and coordinating internationally on standards and policy development.

The company further recommends involving technical and security experts when developing policy and regulatory requirements related to quantum safety.

These recommendations reflect Google's position that PQC preparation requires coordination across organizations, technology providers, governments, and standards bodies.

## 
How Google Is Implementing Post-Quantum Cryptography

Google says it has been deploying PQC for several years. The company highlights several areas of implementation:

- **Chrome:** [Hybrid Kyber/ML-KEM key exchange to protect browser traffic](https://blog.chromium.org/2023/08/protecting-chrome-traffic-with-hybrid.html).
- **Android:** [Post-quantum cryptography work within the Android ecosystem](https://blog.google/security/security-for-the-quantum-era-implementing-post-quantum-cryptography-in-android/).
- **Cloud Key Management Service (Cloud KMS):** [Quantum-safe digital signatures](https://cloud.google.com/blog/products/identity-security/announcing-quantum-safe-digital-signatures-in-cloud-kms).
- **Internal communications:** [PQC protections for Google's internal communications](https://cloud.google.com/blog/products/identity-security/why-google-now-uses-post-quantum-cryptography-for-internal-comms?e=48754805).
- **Wiz PQC readiness scanner:** [A tool designed to assess readiness across code, cloud, and runtime environments](https://www.wiz.io/blog/wiz-for-pqc-readiness).

Google also says it co-founded the [Post-Quantum Cryptography Alliance](https://pqca.org/) at the Linux Foundation with industry participants including Amazon Web Services, Cisco, IBM, and NVIDIA. The initiative supports open-source efforts such as [Open Quantum Safe](https://openquantumsafe.org/).

These examples provide context for Google's migration advice. They do not mean that every Google product, customer workload, or organizational system has completed a transition to PQC.

## How Organizations Can Build Their Own PQC Learning Resource

Google also explains how organizations can create an internal learning resource based on the approach used for its Gemini Notebook.

The company recommends four practices:

**Curate trusted sources.** Assemble authoritative research, standards, and technical guidance relevant to the organization's needs.

**Use neutral prompts.** Write instructions that encourage factual responses grounded in the selected sources.

**Explain the limits of AI-generated content.** Include a welcome message and clear disclaimers so readers understand the notebook's scope and the possibility of errors.

**Require human review.** Have qualified experts verify generated materials before distributing them to employees or using them in security planning.

This approach can help teams make specialized material easier to navigate while preserving the importance of expert oversight. The notebook should support learning and research, not replace technical validation or formal risk assessments.

## 
Analysis: PQC Readiness Is an Inventory and Migration Challenge

Google's announcement highlights a broader industry shift toward treating post-quantum cryptography as a long-term security planning issue rather than a future research topic.

For enterprises, the challenge extends beyond selecting new cryptographic algorithms. Organizations must first identify where existing cryptography is used, determine which information needs long-term protection, understand system dependencies, and plan how changes can be introduced safely.

AI-assisted learning tools such as the Gemini Notebook may make technical information easier to explore. However, they do not remove the need for accurate inventories, engineering assessments, migration testing, and human review.

The practical value of the notebook will depend on how organizations use its material to inform their own environments and decisions. Google's warning that generated responses can contain errors is particularly relevant when the subject involves cryptographic design and security architecture.

## 
Conclusion: Preparing for the Post-Quantum Transition

Google Cloud's new Gemini Notebook provides a public starting point for CISOs, policymakers, developers, and other professionals seeking to understand post-quantum cryptography.

The resource combines curated research with interactive learning features, while Google's wider guidance emphasizes cryptographic inventories, data prioritization, system dependencies, and crypto-agility.

For organizations, the central message is to begin assessing their cryptographic exposure before quantum capabilities create an immediate migration deadline. The notebook can help teams build foundational knowledge, but meaningful readiness will still require organization-specific planning, technical expertise, and ongoing review.
