Wall Street is suddenly treating quantum computing as more than a science‑fiction footnote in the Bitcoin story. A high‑profile strategist has just walked away from a major Bitcoin position, arguing ...

BTQ’s Bitcoin-like quantum testnet explores post-quantum signatures, exposed public keys and why “old BTC risk” is an ...

A warning from a senior Coinbase executive has reignited concerns about how quantum computing could one day reshape Bitcoin’s security, with new estimates suggesting that roughly a third of the ...

"Our quantum error-correcting code has a greater than 1/2 code rate, targeting hundreds of thousands of logical qubits," explains Kasai. "Moreover, its decoding complexity is proportional to the ...

A multinational team has cracked a long-standing barrier to reliable quantum computing by inventing an algorithm that lets ordinary computers faithfully mimic a fault-tolerant quantum circuit built on ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

Two-dimensional projection of a quantum spherical code composed of two copies (black and red) of the four complex dimensional Witting polytope. This code can correct up to five photon losses of any ...
