SH2381 Quantum Information 7.5 credits

Physical and information theoretic principles of quantum intoformation technology.
Quantum mechanical measurements, time development for open quantum systems, density matrices.
Qubits, quantum gates and quantum circuits. Universal quantum gates.
Quantum mechanical entanglement and teleportation and quantum cryptography.
Examples of important quantum algorithms. Quantum superiority.
Interference, decoherence, bit errors and error correction.

After completion of the course, you should be able to:

• describe the principles of qubits, different types of quantum gates and quantum circuits
• analyze the properties of simpler quantum algorithms
• perform calculations of simpler quantum information processes
• describe the principles of quantum teleportation and quantum cryptography
• explain the mechanisms behind bit errors and quantum error correction
• perform and report on laboratory work related to quantum information

Completed course in quantum mechanics, corresponding to the content of course SI2380.

If the course is discontinued, students may request to be examined during the following two academic years.

• INL1 - Homework problems, 6.0 credits, grading scale: A, B, C, D, E, FX, F
• LAB1 - Laborations, 1.5 credits, grading scale: P, F

Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.

The examiner may apply another examination format when re-examining individual students.
