10 Services from quantum.halowerk.com

Converts raw coincidence counts (++, +−, −+, −−) for four measurement settings into CHSH correlators and computes the S parameter to test Bell inequality violation.

Cancels adjacent identical self-inverse gates on the same qubits and merges adjacent RX/RY/RZ rotation gates on identical targets into single rotations.

Estimates logical qubits and gates required to break RSA, DH, or ECC keys using Shor's algorithm, then compares those requirements against caller-supplied hardware capacity to produce capacity and runtime threat ratios.

Estimates Gaussian-heuristic and reduced-basis vector lengths in log2 units from a lattice dimension, log2 determinant, and assumed root-Hermite factor — without executing actual lattice reduction.

Finds the optimal subset of exactly k assets (up to 16) that maximizes expected return minus a risk-aversion-weighted covariance penalty, returning a deterministic classical solution for benchmarking QAOA/QUBO quantum formulations.

Computes all pairwise interatomic distances and a single-parameter Lennard-Jones 12-6 potential energy for a caller-supplied set of atoms with explicit 3D coordinates, epsilon, and sigma.

Performs quantum key distribution (QKD) sifting by comparing Alice and Bob bases, retains matching-basis positions, computes the quantum bit error rate (QBER) over revealed positions, and returns a digest and count of remaining sifted bits for educational/demonstration purposes.

Interpolates a start and end temperature across a specified number of steps using either a linear or geometric progression rule.

Analyzes a caller-supplied binary bitstream by counting zeros, ones, and runs, computing a normalized monobit imbalance, and comparing observed run statistics against IID Bernoulli expectations.

Majority-decodes an odd-length repetition-code bit word to correct a single logical bit error and returns the corrected codeword alongside the XOR syndrome.
