Hi, I’m Henry Sheehy, a theoretical physicist.
I research quantum computing and help people find their way into it.
Quantum Researcher at Qubitera
I work on quantum algorithms, moving between papers, mathematics, code, and the search for genuinely useful quantum capabilities.
Teaching from first principles
I teach difficult ideas from first principles and build the courses, software, and scientific platforms I wish had existed when I began.
Research
Superconductivity and quantum matter
My doctoral thesis proposed microscopic theories of time-reversal symmetry-breaking in superconductors.
Quantum computing
I study quantum algorithms and quantum information, moving between mathematical proposals, physical systems, code, and tests.
Publications and software
The work appears as papers, thesis chapters, technical notes, and software for modelling crystals, superconductors, and quantum systems.
Platforms
TutorLumin — foundations
School mathematics becomes mechanics, waves, probability, and the habits needed for advanced science. TutorLumin offers rigorous teaching and a community for ambitious students beginning that route.
QuantaLumin — mastery and participation
Courses lead into research tools, publishing, workspaces, software, projects, and discussion: a place to study quantum computing seriously and begin contributing.
TechnoAntiques — science through design
Objects, diagrams, interfaces, architecture, and visual culture reveal how scientific ideas take form and how new technology enters everyday life.
Learn
Build the foundations
Strengthen the mathematics, physics, and scientific habits that quantum computing depends on.
Master quantum computing
Begin with states, amplitudes, measurement, and circuits; then connect the mathematics to algorithms, physical systems, and research.
Learn in public
Follow explanations, notes, seminars, videos, and mentoring as ideas move from first encounter to working understanding.
Notes
A theoretical physicist’s notes on building an independent life
Writing on science, books, learning, nutrition, exercise, work, technology, and the systems that support a capable and self-directed life.
Learning and work
How I study difficult subjects, organise long projects, use AI and software, and protect time for serious thought.
Health and movement
Experiments with food, strength, mobility, recovery, and the physical routines that make sustained intellectual work possible.
About
