Quantum Chat

QuantumChat — The world's first quantum and post-quantum messaging app.

QuantumChat is not just a messaging app. It is a complete security ecosystem designed to protect your communications against any threat, present or future.

Because privacy can no longer depend only on traditional technology. Now, your privacy is protected by quantum physics.

What makes QuantumChat unique?

QuantumChat combines the most advanced security technologies in the world:

Quantum and Post-Quantum Technology
• Quantum Random Keys (QRNG)
QuantumChat keys are not generated by conventional software. They are created using a Quantum Real Generator (QRNG), impossible to predict or manipulate.
• Key management within Hardware HSM
Your keys are protected within a military grade HSM module.
• Post-Quantum Cryptography selected by NIST
We include the most advanced standards:
• ML-KEM (formerly CRYSTALS-Kyber) for key exchange.
• ML-DSA (formerly CRYSTALS-Dilithium) for digital signatures.

Guaranteed Post-Quantum Protection

Even if someone invents a quantum supercomputer tomorrow, your messages will still be safe.
True end-to-end encryption: No one but you and your contact can read your messages. Neither us, nor governments, nor hackers.

Active protection with Artificial Intelligence in real time

QuantumChat integrates active defense using advanced AI, capable of detecting and blocking:
• Malware
• Unknown threats
• Malicious SMS
• Phishing
• Invisible attacks
• Zero-Click Attacks (the most dangerous in the world)

What is a Zero-Click attack?

It is an attack that does not require the victim to do anything. No click, no open, no download.
Just by receiving a message, the attack is executed automatically. QuantumChat is prepared to defend you from this as well.
