QBronze is QWorld’s Bronze workshop series (three-day or two-day long) on the basics of quantum computing and quantum programming. Bronze is the name of our workshop material, a collection of Jupyter notebooks using Python as the programming language and Qiskit library for writing quantum programs.

We hit 30 QBronze (18 different cities in 13 countries and 561 handed out diplomas) on March 8, 2020. You can see the list at the end of this page.

The outline of a typical QBronze

A typical name of our workshop is “Introduction to Quantum Programming”. Our workshop material Bronze can be downloaded from our QKitchen:


Bronze is composed by main, auxiliary, and reference notebooks. The auxiliary notebooks are prepared to be used before the workshops. They are for testing the system, reviewing the basics of python, and explaining vectors, matrices, and basic operations on them. The main notebooks are prepared to be used during the workshops.

Before the workshop

Each participant should do certain installations and then test her system by following the instruction in “installation.txt”.

There are two sets of notebooks for reviewing the basics of python and for explaining vectors, matrices, and basic operations on them. The participant is expected to check them before the workshop if she needs.

The first day

  • 09:30 – 10:00: Opening
  • 10:00 – 13:00: Probabilistic bits, coin-flipping, biased coins, probabilistic states, and probabilistic operators, Quantum programs as circuits: registers, gates, measurements, execution, and reading the outcomes
  • 13:00 – 14:00: Lunch break
  • 14:00 – 17:00: Classical correlation, Quantum coin-flipping (Hadamard) and quantum bits (qubits), Quantum states and operators, superposition and measurement, and visualization of a qubit

The second day

  • 10:00 – 13:00: Quantum tomography, controlled-not operation, and phase kick-back
  • 13:00 – 14:00: Lunch break
  • 14:00 – 17:00: Entanglement, superdense coding, and quantum teleportation

The third day

  • 10:00 – 13:00: Rotations, reflections, and multiple controlled operations
  • 13:00 – 14:00: Lunch break
  • 14:00 – 16:30: Grover’s quantum search algorithm and its implementation
  • 16:30 – 17:00: Diploma ceremony and closing remarks


There is no special coffee breaks. There will be short breaks between the notebooks. It is preferable that the tea and coffee are accessible at any moment. If the lunch is in the same venue, then the lunch time can be shorten (45 minutes).

The outline for a prospective QHost

Each host must agree to accept our code of ethics and code of conduct and then respect and follow the codes, rules, and regulations.

We and QHost schedule the dates together.

A. Preparation

  1. QHost determines the number of the participants. We suggest that it should be between 20 and 30.
  2. The workshop must be free of charge for all participants.
  3. QHost arranges a venue for the workshop, which has a projector and a board. While participants are expected to bring their own laptops with them, we would appreciate it indeed if there were at least five computers available on the spot.
  4. It is optional for QHost to provide lunch for the participants. If the lunch is not offered, we expect that there are some eating places close by so that participant would not spend extra time on lunch breaks.
  5. QHost offers tea/coffee and perhaps some cookies during the whole workshop.
  6. QHost provides free WI-FI during the workshop.

B. Application

  1. QHost prepares an application form such as Google forms and shares the responses with us. We will share some templates with QHost to facilitate that.
  2. QHost announces and advertises the event. The logos that we will provide should be on the announcements; we will also share some templates for the poster.
  3. We expect that QHost will especially encourage applications from women and people coming disadvantaged or underrepresented groups.
  4. QHost selects the participants and shares the list with us. QHost may select additional five to ten people among women and disadvantaged or underrepresented groups to make the pool of participants more diverse.

C. Workshop

  1. QHost provides us with local information regarding the event and its venue before and during the workshop.
  2. QHost represents itself during the whole workshop and makes every attempt to ensure that the workshop runs smoothly.

D. Diploma

Traditionally, we award a diploma to every participant who has completed the workshop.

  1. We design a diploma, preferably in color, together with QHost.
  2. QHost prints diplomas, preferably in color, on A4-size thick paper.
  3. The name of each participant is written on a diploma, which is signed by QHost and us.
  4. QHost and we issue diplomas at the end of the workshop.
