Vitalik unveils Lean Ethereum for post-quantum protection

Ethereum developers have revealed a ‘Lean Ethereum‘ roadmap that seeks to simplify the blockchain’s base layer while preparing it for post-quantum security. The proposal was discussed by co-founder Vitalik Buterin and researcher Justin Drake during a Berlin conference session.

The plan prioritises three core goals: enhanced security through post-quantum signatures, reduced complexity in Ethereum’s structure, and improved efficiency to lower latency and costs.

Developers are already exploring four research tracks, including a three-step-finality protocol, quantum-resistant signatures, zero-knowledge virtual machines, and improved data layering through erasure coding.

Under the broader ‘lean’ concept, Ethereum may soon adopt lean staking, verifiability for low-power devices, and simplified cryptographic design. Modular logic and formal checks are part of the plan, aligned with zkEVM pilots and inclusion list development.

Although the roadmap doesn’t suggest an immediate upgrade, the Ethereum Foundation described it as a cohesive strategy that ties current innovation to long-term resilience. Core teams will prototype components and assess trade-offs in ongoing working group discussions.

IBM sets 2029 target for quantum breakthrough

IBM has set out a detailed roadmap to deliver a practical quantum computer by 2029, marking a major milestone in its long-term strategy.

The company plans to build its ‘Starling’ quantum system at a new data centre in Poughkeepsie, New York, targeting around 200 logical qubits—enough to begin outperforming classical computers in specific tasks instead of lagging due to error correction limitations.

Quantum computers rely on qubits to perform complex calculations, but high error rates have held back their potential. IBM shifted its approach in 2019, designing error-correction algorithms based on real, manufacturable chips instead of theoretical models.

The change, as the company says, will significantly reduce the qubits needed to fix errors.

With confidence in its new method, IBM will build a series of quantum systems until 2027, each advancing toward a larger, more capable machine.

Vice President Jay Gambetta stated the key scientific questions have already been resolved, meaning what remains is primarily an engineering challenge instead of a scientific one.

Oxford physicists push qubit precision to new heights

Oxford University physicists have achieved a world-first in quantum computing by setting a new record for single-qubit operation accuracy.

Using a trapped calcium ion as the qubit, the researchers controlled its state using electronic microwave signals instead of lasers.

Their experiment produced an error rate of just 0.000015 percent, or one mistake in 6.7 million operations, nearly ten times better than the previous benchmark set by the same team. The breakthrough brings quantum computers a step closer to becoming viable tools.

This more stable and cost-effective approach was conducted at room temperature and without magnetic shielding, simplifying future hardware requirements.

The precision reduces the number of qubits needed for error correction, making future quantum machines potentially smaller and faster.

Despite the milestone, the researchers emphasised the need to improve two-qubit gate fidelity, where error rates remain significantly higher.

The project is part of the UK Quantum Computing and Simulation Hub, with wider support from the National Quantum Technologies Programme.

Quantum light beats AI at its own game in surprise photonic experiment

A small-scale quantum device developed by researchers at the University of Vienna has outperformed advanced classical machine learning algorithms—including some used in today’s leading AI systems—using just two photons and a glass chip.

The experiment suggests that useful quantum advantage could arrive far sooner than previously thought, not in massive future machines but in today’s modest photonic setups.

The team’s six-mode processor doesn’t rely on raw speed to beat traditional systems. Instead, it harnesses a uniquely quantum property: the way identical particles interfere. This interference naturally computes mathematical structures known as permanents, which are computationally expensive for classical systems.

By embedding these quantum calculations into a pattern-recognition task, the researchers consistently achieved higher classification accuracy across multiple datasets.

Crucially, the device operates with extreme energy efficiency, offering a promising route to sustainable AI. Co-author Iris Agresti highlighted the growing energy costs of modern machine learning and pointed to photonic quantum systems as a potential solution.

These early results could pave the way for new applications in areas where training data is limited and classical methods fall short—redefining the future of AI and quantum computing alike.
