Learning Outcomes

Knowledge and Understanding

Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:

• Understand quantum teleportation and quantum cryptography
• Understand what is entanglement for pure and mixed states
• Understand the principles of quantum metrology and what is quantum Fisher information
• Learn how to store, process, and read information using two-level quantum systems (qubits)
• Learn how to store, process and read information using continuous variables (position and momentum). Learn how to use the covariance matrix formalism.
• Understand basic quantum algorithms

Lecture

Summative

This is how we’ll formally assess what you have learned in this module.

Referral

This is how we’ll assess you if you don’t meet the criteria to pass this module.

Repeat

An internal repeat is where you take all of your modules again, including any you passed. An external repeat is where you only re-take the modules you failed.
