QSilver: Intermediate Quantum Computing Workshop (QWorld)

QSilver is QWorld’s intermediate-level quantum computing workshop, designed for learners who have completed QBronze or have equivalent hands-on experience with qubits, quantum gates, and basic quantum circuits. While QBronze introduces the fundamentals, QSilver goes deeper into the mathematical machinery that powers the most important quantum algorithms.

QWorld is a non-profit global organization with a network of local quantum groups called QCousins that organize regional sessions. All workshops are free of charge.

What you’ll learn

QSilver centers on the mathematical and algorithmic foundations that QBronze intentionally deferred. The core topics are:

• Complex numbers in quantum computing: why complex amplitudes are necessary and how they differ from real-valued probability amplitudes
• The quantum Fourier transform (QFT): the circuit construction, the recursive structure, and its efficiency advantage over the classical fast Fourier transform
• Period finding: how the QFT detects periodicity in a function’s output with exponentially fewer queries than any classical algorithm
• Shor’s algorithm: the full algorithm from period finding to integer factorization, including the classical number-theoretic reduction
• Quantum phase estimation: the general technique underlying many quantum algorithms beyond Shor’s

All content is implemented in Python using Qiskit or similar quantum programming frameworks, so participants practice writing real quantum programs throughout the workshop.

Course structure

QSilver runs as a one-week intensive workshop with daily mentored sessions conducted through Discord. Participants work through the QSilver tutorial notebooks at their own pace with support from mentors. Live Q&A sessions are held each day.

Workshops are offered periodically across different regions and time zones through QWorld’s global network. Check qworld.net for the next scheduled session.

Who is this for?

• Learners who have completed QBronze or an equivalent introductory quantum computing course
• Students who want a rigorous treatment of the quantum Fourier transform and Shor’s algorithm
• Quantum computing enthusiasts who learn best in a community environment with mentors
• Participants in any country, especially those without local university quantum programs

Prerequisites

Completion of QBronze or equivalent knowledge: qubits, quantum gates, superposition, and entanglement. Comfort with Python programming. Basic understanding of complex numbers is helpful but will also be covered in the workshop.

Why take this course?

The QFT and Shor’s algorithm are milestones in quantum computing education. Understanding Shor’s algorithm in full detail, rather than at a surface level, separates learners who can engage with quantum algorithm research from those who can only follow tutorials. QSilver provides that understanding in a supported, community environment at no cost.

QWorld’s global reach means workshops run across many time zones with mentors who can communicate in local languages. This makes QSilver accessible to learners who are geographically or financially excluded from university quantum programs.
