A dedicated CoastalQuant research program

Quantum Computing Research

We investigate quantum methods for environmental data and molecular research, with a clear record of what has been studied and what comes next.

How this connects to our technology

CoastalQuant HCHO Research develops formaldehyde measurement and its validation methodology. This separate computing program explores methods that may inform future work. Any transfer requires its own evidence and validation.

Does the data structure survive hardware execution?

A quantum kernel represents relationships between observations. This study examined how closely those relationships survived execution on an IBM Quantum processor compared with an ideal simulation.

Statevector-to-Hardware Reconstruction of a Four-Qubit ZZ Quantum Kernel: A Single-Backend Case Study of Three Execution Jobs

Rostyslav Sipakov · Quantum Reports 2026, 8(3), 93

DOI: 10.3390/quantum8030093 (opens in a new tab)

The experiment used a frozen subset of existing indoor-air monitoring data from duplicate sensors, with PM2.5, PM10, HCHO, and TVOC features. Three separate jobs on ibm_fez compared baseline, dynamical decoupling, and gate twirling. The gate-twirled job most closely reconstructed the ideal reference. Reconstruction fidelity did not track task-label alignment: every hardware kernel stayed at or below its random-label reference.

These are descriptive findings from single jobs on one processor. They do not establish general mitigation efficacy, quantum advantage, a superior classifier, forecasting, source attribution, or validated formaldehyde measurement.

Planned study · R04

Molecular binding on IBM Quantum.

No quantum hardware runs completed for this study.

Can a physical IBM quantum processor distinguish the binding of formaldehyde and ethanol to a model prefilter site?

The study would examine molecular interactions relevant to a prefilter that reduces interference while preserving formaldehyde for measurement. It combines classical computational chemistry with experiments on a physical IBM Quantum processor.

View R04 study & progress

The planned quantum materials study follows a separate research schedule; dates have not been set.

Computational findings would inform hypotheses for physical testing. A material or device would still require laboratory validation under its intended operating conditions.

Evaluation principles

Evidence for each next step.

A publication establishes a record of a specific study. Future use in CoastalQuant HCHO Research would require demonstrated relevance, reproducibility, and validation for the intended application. The planned sensing and measurement workflows remain classical.

01

A defined scientific question

Set the problem, comparison methods, and evaluation criteria before testing. A useful result must answer the question the study was designed to investigate.

02

A fair classical comparison

Compare methods on the same problem and account for preparation, execution, uncertainty, and computational cost. The choice of method follows the evidence.

03

A reproducible record

Publish methods, accessible code and data, and the limits of each result. Document findings that do not support the original hypothesis as well as those that do.
