Quantikz: Essential Tool Elevating Quantum Circuit Visualization
Helpful tools lift the entire field. I’ve relied heavily on Quantikz by Alastair Kay to draw hundreds of quantum circuit diagrams over the years. It’s been my go-to for clean, publication-quality circuits in papers and lectures.

Tight Inapproximability Bounds for Max‑LINSAT Impact Quantum Interferometry
Tight inapproximability of max-LINSAT and implications for decoded quantum interferometry https://t.co/RzBXqS1r1k We establish tight inapproximability bounds for max-LINSAT, the problem of maximizing the number of satisfied linear constraints over the finite field 𝔽_q, where each constraint accepts r values...

Quantum Computing Redefines Problem Solving with Qubits
🚨 Quantum Computers Don’t Think Like Normal Computers 🚨 Quantum Computers Don’t Think Like Normal Computers Your laptop solves problems step by step using bits: 0 or 1. Quantum computers change the rules. Instead of bits, they use qubits — which can be 0 and...

Quantum Threat: Q-Day Could Cripple Global Financial Security
Quantum computers are coming — and in the next decade, could break widely used public-key encryption (RSA, ECC) that secures everything from bank transactions to crypto. Citigroup’s latest report on quantum calls it a trillion-dollar security threat, and they are not...

Certifying Quantum Magic Proven Super‑Exponential Hard
The unbearable hardness of deciding about magic Identifying the boundary between classical and quantum computation is a central challenge in quantum information. In multi-qubit systems, entanglement and magic are the key resources underlying genuinely quantum behaviour. While entanglement is well understood,...

Ethereum's Quantum Roadmap: Replace BLS with Hash Signatures
Now, the quantum resistance roadmap. Today, four things in Ethereum are quantum-vulnerable: * consensus-layer BLS signatures * data availability (KZG commitments+proofs) * EOA signatures (ECDSA) * Application-layer ZK proofs (KZG or groth16) We can tackle these step by step: ## Consensus-layer signatures Lean consensus includes fully replacing BLS...

Understanding What Logical Qubit Count Really Means
One of the trickiest numbers in quantum computing is “logical qubit count.” We often hear phrases such as “This algorithm requires 1,000 logical qubits,” but what is this number actually telling us?
