Quantum Decryption of RSA Is Much Closer Than Expected

The Advanced Quantum Technologies Institute (AQTI) announced a breakthrough algorithm, JVG, on March 2, 2026, claiming it drastically reduces quantum computing resources needed to crack RSA and ECC encryption. JVG allegedly requires 1,000 times fewer qubits and quantum gates than prior methods, with projections suggesting under 5,000 qubits could break widely used encryption standards. This challenges previous timelines for quantum decryption, which assumed such attacks would require millions of qubits and remain decades away, raising urgent concerns about cybersecurity infrastructure. Skeptics question whether JVG introduces hidden trade-offs, such as extreme error correction demands or impractical runtime, which often undermine similar claims in quantum algorithm research. If validated, the algorithm could accelerate the need for post-quantum cryptography adoption, forcing governments and enterprises to expedite migration from vulnerable encryption systems.
