Unlike consumer apps, QVerse offers enterprise-grade admin controls (remote wipe, DLP, audit), quantum-safe encryption, and India-based SaaS deployment with local and global compliance.

Is it available on Android, iOS, web?

Yes—full-featured native apps on mobile and any modern browser, fullysynced. 

What happens if a device is lost?

Admin can erase all app data remotely andrevoke access instantly.

Can users be restricted by file type and size?

Yes. Admin sets granular file/media sharing rules via policies.

Can it be white-labelled or self-hosted?

Yes. Private cloud/on‑premises options are available, especially fordefence or regulated sectors.

Are calls supported?

Currently text and file collaboration; voice/video calling is in the roadmap.

Is data stored outside India?

No—fully compliant with data residency, hosted within India unless privatecloud deployed.

What is lattice-based cryptography?

Lattice-based cryptography is a branch of post-quantum cryptography built on the complexity of mathematical puzzles called lattice problems, like Short Integer Solution (SIS) and Learning With Errors (LWE). These problems are considered so tough that not even quantum computers can crack them. First introduced by Ajtai in 1996 and later developed further by Regev in 2005, this approach now underpins advanced post-quantum algorithms like NTRU and CRYSTALS-Kyber.

Why is lattice-based cryptography considered quantum-safe?

Traditional encryption methods such as RSA and ECC are vulnerable to quantum attacks—specifically from Shor’s algorithm, which can break them with ease. In contrast, lattice-based problems like SIS and LWE stay hard even in the face of quantum computing. That’s why many experts consider these systems genuinely quantum-safe and future-proof.

What is some common lattice-based cryptographic schemes?

Among the most widely adopted lattice-based schemes are NTRU and CRYSTALS-Kyber. NTRU is based on polynomial rings and the SIS problem, while Kyber is a key encapsulation mechanism (KEM) that’s part of NIST’s post-quantum cryptography standardization push. Both are designed to be secure even against quantum adversaries.

Is WhatsApp quantum-safe?

WhatsApp is NOT quantum safe. WhatsApp uses Curve25519 elliptic curve cryptography (ECC), which—while strong by today’s standards—is breakable by quantum computers using Shor’s algorithm. It hasn't yet integrated any lattice-based cryptography or hybrid post-quantum encryption.

Is Signal quantum-safe?

Signal uses X25519 (another ECC method) and uses its own PQDXH protocol to support post-quantum cryptography and this is at the level 2 security level, whereas other players, such as Apple iMessage use level 3 security (still susceptible to break by quantum computes) and QNu Labs’ QVerse (unhackable by quantum computers) uses 100% NIST compliance PQC algorithms with future advanced end-to-end quantum-security. This means that once large-scale quantum computers are viable, Signal’s encryption protocol would be at risk.

Are Telegram, Slack, Skype, or Microsoft Teams quantum-safe?

No, these messaging and collaboration apps still depend on classical ECC and standard TLS protocols. None of them currently implement quantum-safe encryption methods like lattice-based schemes or hybrid models.
‍Slack's Current Encryption in Details (Source: Slack Security) 
‍Data in transit: Slack uses TLS 1.2 protocols to encrypt data transmitted between users and the Slack servers. 
‍Data at rest: Slack encrypts stored data using AES-256 encryption. 
‍No end-to-end encryption: This means that Slack, as a service provider, can access and potentially decrypt user messages, unlike end-to-end encrypted messaging apps where only the sender and receiver can decrypt the message

Is Apple’s iMessage protected against quantum threats?

To some extent. iMessage relies on ECC encryption and hasn’t adopted lattice-based KEMs. Apple uses PQ3 (Level 3 Security) to be compliant with PQC to some extent with PQC key establishment, and ongoing PQC rekeying. Unless Apple makes a shift, it won’t be secure in the quantum computing world.

What about third-party apps like GB Messenger?

GB Messenger, being a modified version of WhatsApp, uses the same Curve25519 ECC encryption. Since it hasn't introduced any post-quantum cryptography, it faces the same vulnerabilities as its parent app when quantum threats arrive.

What is the pricing model for QVerse?

QVerse follows a tiered subscription model tailored to enterprise needs, offering per-user or per-group pricing. Volume licensing and regulatory bundle options are available for BFSI, legal, defense, PSU, and other clients. Custom integrations or audit/reporting modules may carry a one-time setup fee. Contact us for a demo and quote based on your deployment scale.

I don’t understand the value of Qverse. How is it different from other secure messengers?

Qverse isn’t just another encrypted chat tool—it’s designed for sensitive environments like defense, BFSI, pharma, and government. Here’s what sets it apart:

‍Post-quantum encryption: Traditional apps use ECC; Qverse uses hybrid cryptography, combining AES-256 with quantum-safe key encapsulation (Kyber/NTRU).
Message Vault & No-Screenshot Policy: High-value data (e.g., passwords, OTPs, trade secrets) is secured in an access-controlled vault—can't be screenshotted or forwarded.
Audit Trails & Remote Wipe: Admins can monitor sessions, manage access, and even remotely delete data on lost devices.

Other apps secure messages in transit. QVerse locks them before, during, and after communication—and enforces it with granular admin controls.

Why should I invest in QVerse right now?

Because your existing encryption has an expiry date. ECC and RSA, used by 90% of messaging tools, are vulnerable to quantum decryption. Nation-state and APT actors are already harvesting encrypted data today to break it later (Y2Q risk).

Across industries, breaches show secure-looking 1:1 or group messages are often intercepted:
QVerse protects your people and teams from interception, data exfiltration, and improper access—even from internal or external adversaries.

What’s at stake across sectors:‍

Government, BFSI, Telco: The TeleMessage breach exposed metadata and message logs of over 60 US officials moldstud.com
BFSI: Internal messages from client advisors stolen via desktop sync folders.
Corporate & Legal: Slack, Discord, Microsoft services had major leaks of messages/files affecting millions techepages.com
Telecom: MITM hacking of voice/text records (Salt Typhoon) shows encryption at rest/transit is vulnerable people.com+1nypost.com+1
Cross-Platform Messaging: Push notification leaks via Firebase expose metadata/content arxiv.org
Legal & Pharma: Screenshots of case details shared via Signal/Slack.
Aviation: Group comms leaked during supply chain handoffs.

QVerse gives youtrue E2E quantum encryption using NIST-standardized algorithms (e.g., Kyber, NTRU, Lattice). Its differentiators are:

Consent based message sharing, forward secrecy/ Control based data sharing
Control who gets access to your confidential documents
Containerized security, timed deletion, vaulting, screen restriction, and server + device-level access controls
No geo-location tracking | Provides maximum document and IPR security
Unbreakable security without relying on a third party; data stays on the premise

Given Regulatory compliance with upcoming legislation demanding post quantum readiness, QVerse is a must for every organization. It’s future-proof, zero-trust by design, and enterprise-ready.

Why does encryption have an expiry date?

Algorithms like RSA-2048 and ECC-256 are mathematically breakable by Shor’s algorithm on a large enough quantum computer. Even before that, side-channel attacks and hardware-based key theft were growing. Data that’s encrypted today could be decrypted tomorrow—unless your encryption remains resistant even under quantum conditions, like with Kyber or LWE-based lattice cryptography.

What is Y2Q Risk (Quantum Apocalypse) and why is it significant?

Y2Q Risk stands for "Years to Quantum" risk — the projected point in time when quantum computers become powerful enough to break the encryption systems that currently safeguard our digital world. Unlike classical computers, quantum machines can solve certain problems exponentially faster, including factoring large prime numbers, which threaten widely used cryptographic protocols like RSA and ECC (Elliptic Curve Cryptography).

Why is Y2Q Risk So Significant?

The significance of Y2Q risk lies in its potential to cripple global cybersecurity. Most of today’s digital infrastructure—banking systems, government databases, internet communications, cloud platforms, and even defense operations—rely on encryption that quantum computers could eventually dismantle.

Here’s why it demands immediate attention:

Harvest Now, Decrypt Later (HNDL): Adversaries can already capture encrypted data today and wait for quantum capabilities to decrypt it in the future. Sensitive data like state secrets, medical records, or trade secrets may still hold value even years down the line.
Long-Term Digital Assets at Risk: Data with long shelf life—patents, intellectual property, legal records—are especially vulnerable. Once quantum decryption becomes viable, historical data that was thought to be secure may be instantly compromised.
Zero-Day for Encryption: The day Y2Q arrives could act like a "zero-day event" for global encryption. Organizations not prepared with quantum-safe measures might face catastrophic breaches overnight.
Global Digital Trust at Stake: Encryption is the backbone of digital trust. A quantum attack could lead to financial fraud, misinformation spread, identity theft, and massive reputational damage, undermining confidence in digital ecosystems.
Enable vault, timer messages, remote wipe, and other modules based on department needs.

Preparing for the Inevitable

While Y2Q isn’t here yet, estimates range from 7 to 15 years before large-scale quantum computers emerge. That may sound like a distant future, but considering the time it takes to upgrade cryptographic infrastructure at scale, the clock is already ticking.

Governments, enterprises, and cybersecurity leaders are now investing in quantum-safe cryptography—algorithms designed to resist attacks from quantum computers. This proactive shift is called crypto-agility, and it’s essential for resilience in a post-quantum world.

Final Thought

Y2Q risk is not science fiction—it's a real and growing threat. Just like Y2K forced a global software update, Y2Q demands a global encryption upgrade. The sooner organizations assess their cryptographic posture and begin transitioning to quantum-resistant technologies, the better prepared they will be for the quantum future.

What is the Quantum Apocalypse of Q-Day?

The Quantum Apocalypse is a term used to describe a future scenario where quantum computers become so powerful that they can break the encryption standards that currently secure the internet, banking systems, defense communications, and nearly every digital transaction we rely on today.

It’s not science fiction—it’s a looming cybersecurity crisis that experts warn could arrive within the next 10 to 15 years, or possibly sooner. The threat is serious enough that governments, defense agencies, and Fortune 500 companies are already taking preventive action.

What is Q-Day?

Q-Day refers to the future date when a quantum computer becomes powerful enough to break current public-key encryption systems like RSA, ECC (Elliptic Curve Cryptography), and DH (Diffie-Hellman). On this day, the digital security infrastructure that protects our internet, banking, government, healthcare, and defense communications could be rendered obsolete.

Why Is It Called an Apocalypse?

The word “apocalypse” isn’t just dramatic—it reflects the sweeping, global impact of such a quantum breakthrough:

RSA and ECC Encryption Would Collapse: These are the encryption standards that protect everything from WhatsApp messages to government secrets. Quantum computers could crack them in hours or minutes.
Massive Data Breaches: Everything encrypted today could be decrypted later by quantum attackers—this is known as Harvest Now, Decrypt Later (HNDL). Sensitive health records, trade secrets, and classified documents stored securely today could be exposed tomorrow.
Digital Trust Breakdown: Trust in digital platforms would erode overnight. Financial fraud, identity theft, manipulation of communications, and national security breaches could become rampant.

What Causes the Quantum Apocalypse?

The key culprit is Shor’s Algorithm, a quantum algorithm that can factor large numbers exponentially faster than classical algorithms. This ability strikes at the heart of RSA and other public-key cryptosystems, which rely on the difficulty of factoring to remain secure.

Once a sufficiently powerful quantum computer is built—often estimated at needing thousands of stable qubits—the doors open for this kind of catastrophic decryption.
