All projects matching “error-correction”

Estimates logical qubits and logical gates from algorithm family and key size, applies a caller-supplied error-correction overhead, and reports capacity and runtime ratios. The formulas are coarse planning heuristics, not cryptanalytic proof or a forecast of when cryptographically relevant quantum computers will exist.

Generate a styled QR code PNG (base64 in JSON): custom foreground/background hex colours, module size, border, and error-correction level.

Generate scannable QR codes from any text, URL, or structured payload (WiFi, vCard, SMS, email, geo, crypto). Returns PNG by default with JPG, WebP, and SVG output, plus optional error-correction, sizing, color, version, and encoding controls. Simple cURL POST: send qr_data, receive an image.
