Quantum computing isn't some distant science fiction problem anymore. The technology is advancing quickly enough that 2026 might be the year hardware capabilities and cryptographic threats move from academic papers into genuine operational concern. To get a clearer picture of what's actually happening beneath the hype, I spoke with Andrew Cheung, Founder and CEO of 01 Quantum Inc. (OONEF) and CTO at qLABS, about where the field is headed and what matters for investors and operators paying attention.
Stop Counting Qubits the Wrong Way
Here's the problem with most quantum computing headlines: they obsess over raw qubit counts. Andrew Cheung thinks this metric is becoming increasingly meaningless, and he's got a point. Physical qubits are inherently noisy. Error rates pile up fast, which severely limits how much useful computation you can actually extract from them.
What really matters is the number of error-corrected logical qubits. These are different beasts entirely. Logical qubits combine multiple physical qubits with active error correction protocols to create stable computing units that can run longer, more complex algorithms without falling apart.
The key milestone for 2026 isn't how many physical qubits someone can cram onto a chip. It's progress in logical qubit reliability. Investors should be looking for published benchmarks that demonstrate sustained error suppression and credible roadmaps toward modular fault-tolerant systems. That's where the real breakthroughs will show up.
Error Correction Is the Unlock
Trying to brute-force scale noisy qubits hits diminishing returns pretty quickly. But improvements in error correction compound their value and push usable computing power forward much faster.
Cheung believes error correction represents the most viable path toward practical cryptographic impact. If vendors can demonstrate meaningful progress in logical qubit stability this year, it could accelerate both capital allocation and commercial timelines across the entire quantum ecosystem. This isn't incremental progress; it's the difference between interesting research and something that actually works.
Your Data Is Already Under Attack (Sort Of)
One of the more unsettling security dynamics is something called harvest now, decrypt later. The concept is straightforward and disturbing: adversaries collect encrypted data today, knowing they can't crack it yet, and simply store it until quantum computers become powerful enough to break the encryption.
This threat is particularly acute for long-lived sensitive data like identity records, enterprise archives, and regulated communications. Public blockchains face additional exposure because public keys often remain visible on-chain, creating convenient targets for future cryptanalytic attacks.
As Cheung frames it, the effective risk timeline is already compressed for any assets or data that need to remain secure over long horizons. If your encrypted information needs to stay private for the next decade, you're already in the danger zone.
Standards Are Getting Real
Post-quantum cryptography is transitioning from theory into operational adoption. NIST has finalized its initial standards, and additional guidance is expected to follow throughout 2026.
This year, enterprises should expect more validation programs, procurement requirements, and platform-level integration of quantum-safe algorithms. These shifts matter for investors because standards adoption drives actual spending and vendor selection. It's the difference between everyone talking about quantum security and companies actually cutting checks for it.
Crypto Has a Coordination Problem
Cryptocurrency ecosystems remain slower to adopt quantum protection, and the reasons are structural. Upgrading base layer protocols impacts wallets, custody systems, and transaction formats across entire decentralized networks. Governance and coordination challenges make these transitions messy.
Even when consensus exists around what needs to happen, major upgrades can take years to execute without disrupting users or breaking compatibility. Near-term protection is more likely to emerge through layered approaches like hybrid wallets or opt-in security mechanisms rather than wholesale base layer migrations. It's not ideal, but it's pragmatic given the constraints.
Five Signals Worth Tracking This Year
So what should you actually be watching in 2026? Cheung's framework boils down to five key signals:
1. Demonstrated improvements in logical qubit stability and error suppression from major hardware vendors.
2. Expansion of post-quantum standards into compliance and procurement frameworks at the enterprise and government level.
3. Default post-quantum cryptography support rolling out across cloud platforms and operating systems.
4. Crypto infrastructure launching practical quantum protection without degrading user experience.
5. Increased government guidance and enforcement activity tied to cryptographic risk management.
Quantum risk isn't theoretical anymore. As Cheung's perspective makes clear, progress in logical qubits and adoption of post-quantum cryptography will shape both technology investment and security strategy this year. The organizations that prepare now, before timelines compress even further, will be the ones that come out ahead.
