If this unit does not have an online alternative, then students who are presently unable to enter Western Australia and whose studies would be delayed by an inability to complete this unit, should contact the unit coordinator (details given on this page) to ascertain, on an individual case-by-case basis, if alternate arrangements can be made to support their study in this unit.

Semester 2UWA (Perth)Face to face Predominantly face-to-face. On campus attendance required to complete this unit. May have accompanying resources online.

  • Level 3 core unit in the Frontier Physics major sequence
Quantum Field Theory provides the best known description of the natural world on subatomic length scales that has been tested to amazing precision, and it underpins the current development of quantum technology and its applications at the frontiers of physics.

In this unit, students will learn about (1) introduction to quantum field theory — Lagrangians and actions, the simple harmonic oscillator, creation and annihilation operators, Heisenberg and Schrödinger pictures, coherent states, Klein Gordon equation, Fock space, path integrals, propagators and interactions, Dirac equation; (2) introduction to quantum technology, which may include topics such as quantum control, quantum sensors, quantum imaging, quantum information processing, quantum communication, quantum cryptography, precision measurement and metrology. The content is explored with reference to a range of applications and physical contexts, and developed and applied through a series of laboratory tasks. Skills in problem identification and mathematical solution are fostered through assignment sheets and tutorial activities.
Students are able to (1) analyse the concepts and physical principles involved in quantum field theory and quantum technologies; (2) communicate ideas, both orally and written, relating to quantum field theory and quantum technologies; (3) solve problems in a range of realistic physical situations; (4) execute an advanced experiment relevant to the frontiers of physics; and (5) evaluate the results of an advanced experiment relevant to the frontiers of physics.
Indicative assessments in this unit are as follows: (1) laboratories; (2) assignments; and (3) in-semester tests and final examination. Further information is available in the unit outline.

To pass this unit, a student must: (a) achieve an overall mark of 50 per cent or higher for the unit; and (b) achieve the requisite requirements(s) or a mark of 50 per cent or greater, whichever is higher and specified in the unit outline, for the laboratories component.

Supplementary assessment is available in this unit for those students who obtain a mark of at least 45 overall provided they have also obtained a mark of at least 45 in a specified component of the unit.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Unit readings, including any essential textbooks, are listed in the unit outline for each unit, one week prior the commencement of study. The unit outline will be available via the LMS and the UWA Handbook one week prior the commencement of study. Reading lists and essential textbooks are subject to change each semester. Information on essential textbooks will also be made available on the Essential Textbooks. This website is updated regularly in the lead up to semester so content may change. It is recommended that students purchase essential textbooks for convenience due to the frequency with which they will be required during the unit. A limited number of textbooks will be made available from the Library in print and will also be made available online wherever possible. Essential textbooks can be purchased from the commercial vendors to secure the best deal. The Student Guild can provide assistance on where to purchase books if required. Books can be purchased second hand at the Guild Secondhand bookshop (second floor, Guild Village), which is located on campus.
