When Will Quantum Computers Break Encryption? An Honest Answer
When will quantum computers break encryption? The honest answer is that nobody knows the date. Quantum computing timelines are uncertain due to the immense technical challenges involved. Today's quantum processors, like IBM's Condor with 1,121 physical qubits, are noisy and far from the millions of qubits needed to break cryptography like Bitcoin's ECDSA. NIST finalised post-quantum standards in 2024 to prepare for the eventual risk, but the 'harvest now, decrypt later' threat means the timeline is partly irrelevant.
Part of the BMIC quantum series. For the full background — the threat, the NIST standards and the buying checklist — start with the quantum crypto presale guide.
5 signals to watch instead of guessing a date
- Understand the uncertaintyExpert estimates vary widely on when quantum computers will break encryption, as today's hardware is far from cryptographically relevant.
- Recognise the 'harvest now' riskAdversaries can record encrypted data and exposed public keys today, decrypting them once quantum hardware matures.
- Check your crypto's signature schemeBitcoin and Ethereum use ECDSA, Solana uses Ed25519, and XRP supports both — none are post-quantum secure.
- Look for NIST-standard post-quantum cryptographyNIST finalised standards like FIPS-203 (CRYSTALS-Kyber for key encapsulation) and FIPS-204 (CRYSTALS-Dilithium for signatures) in 2024.
- Consider quantum-resistant walletsQuantum-resistant wallets like BMIC use NIST-standard post-quantum cryptography to protect against future threats.

Why the timeline is uncertain
The timeline for quantum computers breaking encryption is uncertain because today's hardware is far from cryptographically relevant. IBM's Condor processor reached 1,121 physical qubits in 2023, but a 2022 University of Sussex study estimated roughly 13 million physical qubits are needed to break Bitcoin's ECDSA within a day, and 300 million within an hour. These machines must also be fault-tolerant, a significant technical challenge. Grover's algorithm, which halves symmetric/hash security, is less of a threat — SHA-256 retains ~128-bit strength. However, the 'harvest now, decrypt later' risk means adversaries can record encrypted data today and attack it once quantum hardware matures.
How to prepare for quantum threats
Preparing for quantum threats starts with understanding your crypto's signature scheme. Bitcoin and Ethereum use ECDSA, Solana uses Ed25519, and XRP supports both — none are post-quantum secure. NIST finalised post-quantum standards in 2024, including FIPS-203 (CRYSTALS-Kyber for key encapsulation) and FIPS-204 (CRYSTALS-Dilithium for signatures). Quantum-resistant wallets like BMIC adopt these standards to protect against future threats. BMIC's wallet uses CRYSTALS-Kyber class key encapsulation, aligning with NIST's recommendations. Its presale includes a working wallet for free, offering immediate protection against 'harvest now, decrypt later' attacks.

Frequently asked questions
Can quantum computers break encryption today?
No, today's quantum computers are far from cryptographically relevant.
IBM's Condor processor reached 1,121 physical qubits in 2023, but millions are needed to break encryption like Bitcoin's ECDSA.
What is 'harvest now, decrypt later'?
It means adversaries can record encrypted data today and decrypt it once quantum hardware matures.
This makes the timeline for quantum threats partly irrelevant, as the risk begins before any 'Q-Day'.
Is Bitcoin quantum-resistant?
No, Bitcoin uses ECDSA signatures, which are vulnerable to quantum attacks.
A 2022 University of Sussex study estimated roughly 13 million physical qubits are needed to break Bitcoin's ECDSA within a day.
What is BMIC's quantum-resistant solution?
BMIC uses NIST-standard post-quantum cryptography, specifically CRYSTALS-Kyber class key encapsulation.
Its wallet is a working product, audited and free with a presale purchase, offering immediate protection against quantum threats.
